arm64: soc: ZynqMP SoC fixes for v5.7
- Fix firmware driver dependency

Compile-testing the driver can result in a link failure
when CONFIG_SOC_BUS is disabled:
x86_64-linux-ld: drivers/soc/imx/soc-imx8m.o: in function `imx8_soc_init':
soc-imx8m.c:(.init.text+0x28d): undefined reference to `soc_device_register'
Select it from Kconfig, as we do from the other SoC drivers.

A 1024 byte variable on the stack will warn on any 32-bit architecture
during compile-testing, and is generally a bad idea anyway:
fsl/dpio/dpio-service.c: In function 'dpaa2_io_service_enqueue_multiple_desc_fq':
fsl/dpio/dpio-service.c:495:1: error: the frame size of 1032 bytes is larger than 1024 bytes [-Werror=frame-larger-than=]
There are currently no callers of this function, so I cannot tell whether
dynamic memory allocation is allowed once callers are added. Change
it to kcalloc for now, if anyone gets a warning about calling this in
atomic context after they start using it, they can fix it later.

Building dpio for 32 bit shows a new compiler warning from converting
a pointer to a u64:
drivers/soc/fsl/dpio/qbman-portal.c: In function 'qbman_swp_enqueue_multiple_desc_direct':
drivers/soc/fsl/dpio/qbman-portal.c:870:14: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
870 | addr_cena = (uint64_t)s->addr_cena;
The variable is not used anywhere, so removing the assignment seems
to be the correct workaround. After spotting what seemed to be
some confusion about address spaces, I ran the file through sparse,
which showed more warnings:
drivers/soc/fsl/dpio/qbman-portal.c:756:42: warning: incorrect type in argument 1 (different address spaces)
drivers/soc/fsl/dpio/qbman-portal.c:756:42: expected void const volatile [noderef] <asn:2> *addr
drivers/soc/fsl/dpio/qbman-portal.c:756:42: got unsigned int [usertype] *[assigned] p
drivers/soc/fsl/dpio/qbman-portal.c:902:42: warning: incorrect type in argument 1 (different address spaces)
drivers/soc/fsl/dpio/qbman-portal.c:902:42: expected void const volatile [noderef] <asn:2> *addr
drivers/soc/fsl/dpio/qbman-portal.c:902:42: got unsigned int [usertype] *[assigned] p
Here, the problem is passing a token from memremap() into __raw_readl(),
which is only defined to work on MMIO addresses but not RAM. Turning
this into a simple pointer dereference avoids this warning as well.

The firmware driver is optional, but the power driver depends on it,
which needs to be reflected in Kconfig to avoid link errors:
aarch64-linux-ld: drivers/soc/xilinx/zynqmp_power.o: in function `zynqmp_pm_isr':
zynqmp_power.c:(.text+0x284): undefined reference to `zynqmp_pm_invoke_fn'
The firmware driver can probably be allowed for compile-testing as
well, so it's best to drop the dependency on the ZYNQ platform
here and allow building as long as the firmware code is built-in.

Pull RISC-V updates from Palmer Dabbelt:
"This contains a handful of new features:
- Partial support for the Kendryte K210.
There are still a few outstanding issues that I have patches for,
but I don't actually have a board to test them so they're not
included yet.
- SBI v0.2 support.
- Fixes to support for building with LLVM-based toolchains. The
resulting images are known not to boot yet.
I don't anticipate a part two, but I'll probably have something early
in the RCs to finish up the K210 support"

Add support for the Kendryte K210 RISC-V SoC. For now, this support
only provides a simple sysctl driver allowing to setup the CPU and
uart clock. This support is enabled through the new Kconfig option
SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL
to enable the K210 SoC sysctl driver compilation.
The sysctl driver also registers an early SoC initialization function
allowing enabling the general purpose use of the 2MB of SRAM normally
reserved for the SoC AI engine. This initialization function is
automatically called before the dt early initialization using the flat
dt root node compatible property matching the value "kendryte,k210".

Qualcomm SoCs (starting with MSM8998) allow for multiple protection domains
to run on the same Q6 sub-system. This allows for services like ATH10K WLAN
FW to have their own separate address space and crash/recover without
disrupting the modem and other PDs running on the same sub-system. The PDR
helpers introduces an abstraction that allows for tracking/controlling the
life cycle of protection domains running on various Q6 sub-systems.

Tegra PMC has blink control to output 32 kHz clock out to Tegra blink
pin. Blink pad DPD state and enable controls are part of Tegra PMC
register space.
Currently Tegra clock driver registers blink control by passing PMC
address and register offset to clk_register_gate which performs direct
PMC access during clk_ops and with this when PMC is in secure mode, any
access from non-secure world does not go through.
This patch adds blink control registration to the Tegra PMC driver using
PMC specific clock gate operations that use tegra_pmc_readl() and
tegra_pmc_writel() to support both secure mode and non-secure
mode PMC register access.

Tegra PMC has clk_out_1, clk_out_2, and clk_out_3 clocks and currently
these PMC clocks are registered by Tegra clock driver with each clock as
separate mux and gate clocks using clk_register_mux and clk_register_gate
by passing PMC base address and register offsets and PMC programming for
these clocks happens through direct PMC access by the clock driver.
With this, when PMC is in secure mode any direct PMC access from the
non-secure world does not go through and these clocks will not be
functional.
This patch adds these PMC clocks registration to pmc driver with PMC as
a clock provider and registers each clock as single clock.
clk_ops callback implementations for these clocks uses tegra_pmc_readl and
tegra_pmc_writel which supports PMC programming in both secure mode and
non-secure mode.

When MESON_SECURE_PM_DOMAINS & !MESON_SM, there will be compile failure:
.../meson-secure-pwrc.o: In function `meson_secure_pwrc_on':
.../meson-secure-pwrc.c:76: undefined reference to `meson_sm_call'
Fix this by adding depends on MESON_SM for MESON_SECURE_PM_DOMAINS.

Some cpuidle C-states supported on am335x and am437x, like C1 on am335x,
require the use of the wkup_m3_ipc driver, and all C-states beyond C0 on
both platforms require the use of the SRAM sleep code.
Pass am33xx_do_sram_idle as the idle function to the platform pm core to
be used by the cpuidle-arm driver when entering cpuidle states.
am33xx_do_sram_idle will detect when the wkup_m3 is needed and ping it
if necessary before calling the final cpu_suspend op which will execute
the SRAM code to put the cpu into idle.
Finally, use the begin_suspend and finish_suspend platform ops to be
called at the beginning and end of suspend path to allow use of
cpu_idle_poll_ctrl.
This prevents races between cpuidle and suspend paths trying to
communicate with the wkup_m3, as during suspend we only want it
configured for entry to suspend.

In order for am335x and am437x to properly enter deeper c-states in
cpuidle they must always call into the sleep33/43xx suspend code and
also sometimes invoke the wkup_m3_ipc driver. These are both controlled
by the pm33xx module so we must provide a method for the platform code
to call back into the module when it is available as the core cpuidle
ops that are invoked by the cpuidle-arm driver must remain as built in.
Extend the init platform op to take an idle function as an argument so
that we can use this to call into the pm33xx module for c-states that
need it. Also add a deinit op so we can unregister this idle function
from the PM core when the pm33xx module gets unloaded.

git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into arm/fixes
i.MX fixes for 5.6:
- Build v7_cpu_resume() unconditionally to fix system hang in case that
suspend is disabled but cpuidle support is enabled.
- Drop unexisting Ethernet PHY device from imx8qxp-mek board.
- Fix SRAM compatible strings on imx6dl-colibri-eval-v3 board.
- Fix imx-scu driver to make sure that all messages words are written
sequentially.
- A series from Leonard Crestez to fix i.MX SC API users, having all
messages aligned on 4 bytes.
- Fix eMMC supply for phycore-som board.
- Drop bogus frequency setting from imx7-colibri SD/MMC device, so that
HS200 mode starts working and delivers better performance.
- Fix opp-supported-hw for i.MX7D to get consumer and industrial parts
work with correct frequency settings.
- Restore MDIO compatible to the correct one for LS1021A SoC.

The imx SC api strongly assumes that messages are composed out of
4-bytes words but some of our message structs have odd sizeofs.
This produces many oopses with CONFIG_KASAN=y.
Fix by marking with __aligned(4).
