Since commit 241d2fb56a18 ("of: Make OF framebuffer device names unique"),
as spotted by Frédéric Bonnard, the historical "of-display" device is
gone: the updated logic creates "of-display.0" instead, then as many
"of-display.N" as required.
This means that offb no longer finds the expected device, which prevents
the Debian Installer from setting up its interface, at least on ppc64el.
Fix this by keeping "of-display" for the first device and "of-display.N"
for subsequent devices.

treewide: Fix probing of devices in DT overlays
dt-bindings: interrupt-controller: loongarch: Fix mismatched compatible
|
|
When loading a DT overlay that creates a device, the device is not
probed, unless the DT overlay is unloaded and reloaded again.
After the recent refactoring to improve fw_devlink, it no longer depends
on the "compatible" property to identify which device tree nodes will
become struct devices. fw_devlink now picks up dangling consumers
(consumers pointing to descendent device tree nodes of a device that
aren't converted to child devices) when a device is successfully bound
to a driver. See __fw_devlink_pickup_dangling_consumers().
However, during DT overlay, a device's device tree node can have
sub-nodes added/removed without unbinding/rebinding the driver. This
difference in behavior between the normal device instantiation and
probing flow vs. the DT overlay flow has a bunch of implications that
are pointed out elsewhere[1]. One of them is that the fw_devlink logic
to pick up dangling consumers is never exercised.
This patch solves the fw_devlink issue by marking all DT nodes added by
DT overlays with FWNODE_FLAG_NOT_DEVICE (fwnode that won't become
device), and by clearing the flag when a struct device is actually
created for the DT node. This way, fw_devlink knows not to have
consumers waiting on these newly added DT nodes, and to propagate the
dependency to an ancestor DT node that has the corresponding struct
device.
Based on a patch by Saravana Kannan, which covered only platform and spi
devices.

Since Linux 5.19 this error is observed:
sysfs: cannot create duplicate filename '/devices/platform/of-display'
This is because multiple devices with the same name 'of-display' are
created on the same bus. Update the code to create numbered device names
for the displays.
Also, fix a node refcounting issue when exiting the boot display loop.

Create a platform device for each OF-declared framebuffer and have
offb bind to these devices. Allows for real hot-unplugging and other
drivers besides offb.
Originally, offb created framebuffer devices while initializing its
module by parsing the OF device tree. No actual Linux device was set
up. This tied OF framebuffers to offb and makes writing other drivers
for the OF framebuffers complicated. The absence of a Linux device
further prevented real hot-unplugging. Adding a distinct platform
device for each OF framebuffer solves both problems. Specifically, a
DRM driver can now provide graphics output for modern userspace.
Some of the offb init code is now located in the OF initialization.
There's now also an implementation of of_platform_default_populate_init(),
which was missing before. The OF side creates different devices for
either OF display nodes or BootX displays as they require different
handling by the driver. The offb drivers picks up each type of device
and runs the appropriate fbdev initialization.
Tested with OF display nodes on qemu's ppc64le target.

Now that all the DT drivers have switched to platform_get_irq() we can now
safely drop the static setup of IRQ resource from DT core code.
With the above change hierarchical setup of irq domains is no longer
bypassed and thus allowing hierarchical interrupt domains to describe
interrupts using "interrupts" DT property.

Open Profile for DICE is an open protocol for measured boot compatible
with the Trusted Computing Group's Device Identifier Composition
Engine (DICE) specification. The generated Compound Device Identifier
(CDI) certificates represent the hardware/software combination measured
by DICE, and can be used for remote attestation and sealing.
Add a driver that exposes reserved memory regions populated by firmware
with DICE CDIs and exposes them to userspace via a character device.
Userspace obtains the memory region's size from read() and calls mmap()
to create a mapping of the memory region in its address space. The
mapping is not allowed to be write+shared, giving userspace a guarantee
that the data were not overwritten by another process.
Userspace can also call write(), which triggers a wipe of the DICE data
by the driver. Because both the kernel and userspace mappings use
write-combine semantics, all clients observe the memory as zeroed after
the syscall has returned.

Commit 25b892b583cc ("ARM: dts: arm: Update register-bit-led nodes
'reg' and node names") added a 'reg' property to nodes. This change has
the side effect of changing how the kernel generates the device name.
The assumption was a translatable 'reg' address is unique. However, in
the case of the register-bit-led binding (and a few others) that is not
the case. The 'mask' property must also be used in this case to make a
unique device name.

Pull ARM SoC driver updates from Arnd Bergmann:
"These are all the driver updates for SoC specific drivers. There are a
couple of subsystems with individual maintainers picking up their
patches here:
- The reset controller subsystem add support for a few new SoC
variants to existing drivers, along with other minor improvements
- The OP-TEE subsystem gets a driver for the ARM FF-A transport
- The memory controller subsystem has improvements for Tegra,
Mediatek, Renesas, Freescale and Broadcom specific drivers.
- The tegra cpuidle driver changes get merged through this tree this
time. There are only minor changes, but they depend on other tegra
driver updates here.
- The ep93xx platform finally moves to using the drivers/clk/
subsystem, moving the code out of arch/arm in the process. This
depends on a small sound driver change that is included here as
well.
- There are some minor updates for Qualcomm and Tegra specific
firmware drivers.
The other driver updates are mainly for drivers/soc, which contains a
mixture of vendor specific drivers that don't really fit elsewhere:
- Mediatek drivers gain more support for MT8192, with new support for
hw-mutex and mmsys routing, plus support for reset lines in the
mmsys driver.
- Qualcomm gains a new "sleep stats" driver, and support for the
"Generic Packet Router" in the APR driver.
- There is a new user interface for routing the UARTS on ASpeed BMCs,
something that apparently nobody else has needed so far.
- More drivers can now be built as loadable modules, in particular
for Broadcom and Samsung platforms.
- Lots of improvements to the TI sysc driver for better
suspend/resume support"
Finally, there are lots of minor cleanups and new device IDs for
amlogic, renesas, tegra, qualcomm, mediateka, samsung, imx,
layerscape, allwinner, broadcom, and omap"

of_amba_device_create() uses irq_of_parse_and_map() to translate
a DT interrupt specification into a Linux virtual interrupt number.
But it doesn't properly handle the case where the interrupt controller
is not yet available, eg, when pl011 interrupt is connected to MBIGEN
interrupt controller, because the mbigen initialization is too late,
which will lead to no IRQ due to no IRQ domain found, log is shown below,
"irq: no irq domain found for uart0 !"
use of_irq_get() to return -EPROBE_DEFER as above, and in the function
amba_device_try_add()/amba_device_add(), it will properly handle in such
case, also return 0 in other fail cases to be consistent as before.

Practically all modern Qualcomm platforms has a single reserved-memory
region for SMEM. So rather than having to describe SMEM in the form of a
node with a reference to a reserved-memory node, allow the SMEM device
to be instantiated directly from the reserved-memory node.
The current means of falling back to dereferencing the "memory-region"
is kept as a fallback, if it's determined that the SMEM node is a
reserved-memory node.
The "qcom,smem" compatible is added to the reserved_mem_matches list, to
allow the reserved-memory device to be probed.
In order to retain the readability of the code, the resolution of
resources is split from the actual ioremapping.

Firmware/co-processors might use reserved memory areas in order to pass
data stemming from an nvmem device otherwise non accessible to Linux.
For example an EEPROM memory only physically accessible to firmware, or
data only accessible early at boot time.
In order to expose this data to other drivers and user-space, the driver
models the reserved memory area as an nvmem device.

Iterate over child devices in reverse when unpopulating a platform
device to make this step symmetrical with the population step. This
fixes an issue in the Tegra DRM driver where upon module unload the
DPAUX controller tries to unregister an I2C controller but will end
up waiting indefinitely because one of the SOR devices is keeping a
reference to it. Since the SOR devices are instantiated after the
DPAUX devices, they would only be removed (and hence release their
reference to the I2C controller) after the DPAUX devices have been
removed.
While destroying the child devices in reverse order helps in this
situation, it isn't fully safe to do so either. An even better way
would be for the child devices to be reordered to match the probe
order, which would work irrespective of the instantiation order.
However, reordering by probe order would be fairly complicated and
doesn't fix any known issues, so we'll go with the simpler fix for
now.

The fw_devlink_pause() and fw_devlink_resume() APIs allow batching the

tree nodes in a system.

Commit 5e6669387e22 ("of/platform: Pause/resume sync state during init
and of_platform_populate()") paused/resumed sync state during init only
if Linux had parsed and populated a devicetree.
However, the check for that (of_have_populated_dt()) can change after
of_platform_default_populate_init() executes. One example of this is
when devicetree unittests are enabled. This causes an unmatched
pause/resume of sync state. To avoid this, just unconditionally
pause/resume sync state during init.

When all the top level devices are populated from DT during kernel
init, the supplier devices could be added and probed before the
consumer devices are added and linked to the suppliers. To avoid the
sync_state() callback from being called prematurely, pause the
sync_state() callbacks before populating the devices and resume them
at late_initcall_sync().
Similarly, when children devices are populated from a module using
of_platform_populate(), there could be supplier-consumer dependencies
between the children devices that are populated. To avoid the same
problem with sync_state() being called prematurely, pause and resume
sync_state() callbacks across of_platform_populate().

There is an arbitrary difference between the prototypes of
bus_find_device() and class_find_device() preventing their callers
from passing the same pair of data and match() arguments to both of
them, which is the const qualifier used in the prototype of
class_find_device(). If that qualifier is also used in the
bus_find_device() prototype, it will be possible to pass the same
match() callback function to both bus_find_device() and
class_find_device(), which will allow some optimizations to be made in
order to avoid code duplication going forward. Also with that, constify
the "data" parameter as it is passed as a const to the match function.
For this reason, change the prototype of bus_find_device() to match
the prototype of class_find_device() and adjust its callers to use the
const qualifier in accordance with the new prototype of it.

Summary:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4
- Work to get rid of direct accesses to struct device_node name and
type pointers in preparation for removing them. New helpers for
parsing DT cpu nodes and conversions to use the helpers. printk
conversions to %pOFn for printing DT node names. Most went thru
subystem trees, so this is the remainder.
- Fixes to DT child node lookups to actually be restricted to child
nodes instead of treewide.
- Refactoring of dtb targets out of arch code. This makes the support
more uniform and enables building all dtbs on c6x, microblaze, and
powerpc.
- Various DT binding updates for Renesas r8a7744 SoC
- Vendor prefixes for Facebook, OLPC

This addresses a v4.19-rc1 regression in the PL111 DRM driver in
drivers/gpu/pl111/*
The driver uses the CMA KMS helpers and will thus at some point call
down to dma_alloc_attrs() to allocate a chunk of contigous DMA memory
for the framebuffer.
It appears that in v4.18, it was OK that this (and other DMA mastering
AMBA devices) left dev->coherent_dma_mask blank (zero).
In v4.19-rc1 the WARN_ON_ONCE(dev && !dev->coherent_dma_mask) in
dma_alloc_attrs() in include/linux/dma-mapping.h is triggered. The
allocation later fails when get_coherent_dma_mask() is called from
__dma_alloc() and __dma_alloc() returns NULL:
drm-clcd-pl111 dev:20: coherent DMA mask is unset
drm-clcd-pl111 dev:20: [drm:drm_fb_helper_fbdev_setup] *ERROR*
Failed to set fbdev configuration
It turns out that in commit 4d8bde883bfb ("OF: Don't set default
coherent DMA mask") the OF core stops setting the default DMA mask on
new devices, especially those lines of the patch:
- if (!dev->coherent_dma_mask)
- dev->coherent_dma_mask = DMA_BIT_MASK(32);
Robin Murphy solved a similar problem in a5516219b102 ("of/platform:
Initialise default DMA masks") by simply assigning dev.coherent_dma_mask
and the dev.dma_mask to point to the same when creating devices from the
device tree, and introducing the same code into the code path creating
AMBA/PrimeCell devices solved my problem, graphics now come up.
The code simply assumes that the device can access all of the system
memory by setting the coherent DMA mask to 0xffffffff when creating a
device from the device tree, which is crude, but seems to be what kernel
v4.18 assumed.
The AMBA PrimeCells do not differ between coherent and streaming DMA so
we can just assign the same to any DMA mask.
Possibly drivers should augment their coherent DMA mask in accordance
with "dma-ranges" from the device tree if more finegranular masking is
needed.

When of_dma_configure() was first born in 591c1ee465ce ("of: configure
the platform device dma parameters"), everything DMA-related was
factored out of of_platform_device_create_pdata() as seemed appropriate
at the time. However, now that of_dma_configure() has grown into the
generic handler for processing DMA-related properties from DT for all
kinds of devices, it is no longer an appropriate place to be doing
OF-platform-specific business. Since there are still plenty of platform
drivers not setting their own masks and depending on the bus default,
let's reinstate that inialisation in the OF-platform code itself, and
restore the long-standing status quo from 0589342c2794 ("of: set
dma_mask to point to coherent_dma_mask")

Pull more overflow updates from Kees Cook:
"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of
manual whitespace updates in the patches as well.
Summary:
- Error path bug fix for overflow tests (Dan)
- Additional struct_size() conversions (Matthew, Kees)
- Explicitly reported overflow fixes (Silvio, Kees)
- Add missing kvcalloc() function (Kees)
- Treewide conversions of allocators to use either 2-factor argument
variant when available, or array_size() and array3_size() as needed
(Kees)"

The kzalloc() function has a 2-factor argument form, kcalloc(). This
patch replaces cases of:
kzalloc(a * b, gfp)
with:
kcalloc(a * b, gfp)
as well as handling cases of:
kzalloc(a * b * c, gfp)
with:
kzalloc(array3_size(a, b, c), gfp)
as it's slightly less ugly than:
kzalloc_array(array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
kzalloc(4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

Immediately after the platform_device_unregister() the device will be
cleaned up. Accessing the freed pointer immediately after that will
crash the system.
Found this bug when kernel is built with CONFIG_PAGE_POISONING and testing
loading/unloading audio drivers in a loop on Qcom platforms.
Fix this by moving of_node_clear_flag() just before the unregister calls.

provides information regarding shared resources. Some shared resources
in the SoC have properties that are probed dynamically at boot by the
remote processor. The information pertaining to the SoC and the platform
are made available in the shared memory. Drivers can query this

The OPP tables are present as separate nodes, whose phandle is used in
the "operating-points-v2" property of devices. Currently the OF core
creates a device for the OPP table unconditionally, which is not used by
any kernel code.
This patch creates another OF device_id table for the nodes which must
be skipped while creating devices and OPP is the only user of it for now.
