2023-08-18mfd: tps65086: Read DEVICE ID register 1 from deviceAndre Werner
This commit prepares a following commit for the regulator part of the MFD. The driver should support different device chips that differ in their register definitions, for instance to control LDOA1 and SWB2. So it is necessary to use a dedicated regulator description for a specific device variant. Thus, the content from DEVICEID Register 1 is used to choose a dedicated configuration between the different device variants.

The CS42L43 is an audio CODEC with integrated MIPI SoundWire interface (Version 1.2.1 compliant), I2C, SPI, and I2S/TDM interfaces designed for portable applications. It provides a high dynamic range, stereo DAC for headphone output, two integrated Class D amplifiers for loudspeakers, and two ADCs for wired headset microphone input or stereo line input. PDM inputs are provided for digital microphones. The MFD component registers and initialises the device and provides PM/system power management.

2023-06-15mfd: wm831x: Use maple tree register cacheMark Brown
regmap has introduced a maple tree based register cache which makes use of this more advanced data structure which has been added to the kernel recently. Maple trees are much flatter than rbtrees, meaning that they do not grow to such depths when the register map is sparse which makes access a bit more efficient. The maple tree cache type is still a bit of a work in progress but should be effective for some devices already. The wm831x devices have a pretty sparse register map and being always on devices never do cache syncs so don't hit the major current disadvantage so they should be good candiates for using the maple tree cache. Update to do so, there should be little if any visible difference at runtime.

2023-06-15mfd: intel-m10-bmc: Manage access to MAX 10 fw handshake registersIlpo Järvinen
On some MAX 10 cards, the BMC firmware is not available to service handshake registers during secure update erase and write phases at normal speeds. This problem affects at least hwmon driver. When the MAX 10 hwmon driver tries to read the sensor values during a secure update, the reads are slowed down (e.g., reading all D5005 sensors takes ~24s which is magnitudes worse than the normal <0.02s). Manage access to the handshake registers using a rw semaphore and a FW state variable to prevent accesses during those secure update phases and return -EBUSY instead. If handshake_sys_reg_nranges == 0, don't update bwcfw_state as it is not used. This avoids the locking cost.

2023-06-07TI TPS6594 PMIC support (RTC, pinctrl, regulators)Mark Brown
Merge series from Esteban Blanc <eblanc@baylibre.com>: TPS6594 is a Power Management IC which provides regulators and others features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC can communicate through the I2C or SPI interfaces. TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives. This series adds support to TI TPS6594 PMIC and its derivatives.
2023-06-06regulator: Add X-Powers AXP15060/AXP313a PMICMark Brown
Merge series from Andre Przywara <andre.przywara@arm.com>: This patch series adds support for the X-Powers AXP15060 and AXP313a PMIC, which are general purpose PMICs as seen on different boards with different SOCs, mostly from Allwinner. This is mostly a repost of the previous patches, combining both the AXP313a and AXP15060 series, rebased on top of v6.4-rc3, and omitting the patches that already got merged. The first two patches are the successors of the AXP313a v10 post, the third patch is based on Shengyu's AXP15060 v3 post. There were no code changes, just some tiny context differences due to the rebase, plus I added the newly gained tags. As the DT bindings and the AXP15060 MFD part are already in the tree, this is just completing support with the MFD part for the AXP313a, and the regulator support for both PMICs.

The AXP313a is a PMIC chip produced by X-Powers, it can be connected via an I2C bus. The name AXP1530 seems to appear as well, and this is what is used in the BSP driver. From all we know it's the same chip, just a different name. However we have only seen AXP313a chips in the wild, so go with this name. Compared to the other AXP PMICs it's a rather simple affair: just three DCDC converters, three LDOs, and no battery charging support. Describe the regmap and the MFD bits, along with the registers exposed via I2C. Aside from the various regulators, also describe the power key interrupts, and adjust the shutdown handler routine to use a different register than the other PMICs. Eventually advertise the device using the new compatible string.

2023-05-24ARM/mfd/gpio: Fixup TPS65010 regression on OMAP1 OSK1Linus Walleij
Aaro reports problems on the OSK1 board after we altered the dynamic base for GPIO allocations. It appears this happens because the OMAP driver now allocates GPIO numbers dynamically, so all that is references by number is a bit up in the air. Let's bite the bullet and try to just move the gpio_chip in the tps65010 MFD driver over to using dynamic allocations. Alter everything in the OSK1 board file to use a GPIO descriptor table and lookups. Utilize the NULL device to define some board-specific GPIO lookups and use these to immediately look up the same GPIOs, convert to IRQ numbers and pass as resources to the devices. This is ugly but should work. The .setup() callback for tps65010 was used for some GPIO hogging, but since the OSK1 is the only user in the entire kernel we can alter the signatures to something that is helpful and make a clean transition.

git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux Pull module updates from Luis Chamberlain: "The summary of the changes for this pull requests is: - Song Liu's new struct module_memory replacement - Nick Alcock's MODULE_LICENSE() removal for non-modules - My cleanups and enhancements to reduce the areas where we vmalloc module memory for duplicates, and the respective debug code which proves the remaining vmalloc pressure comes from userspace. Most of the changes have been in linux-next for quite some time except the minor fixes I made to check if a module was already loaded prior to allocating the final module memory with vmalloc and the respective debug code it introduces to help clarify the issue. Although the functional change is small it is rather safe as it can only *help* reduce vmalloc space for duplicates and is confirmed to fix a bootup issue with over 400 CPUs with KASAN enabled. I don't expect stable kernels to pick up that fix as the cleanups would have also had to have been picked up. Folks on larger CPU systems with modules will want to just upgrade if vmalloc space has been an issue on bootup. Given the size of this request, here's some more elaborate details: The functional change change in this pull request is the very first patch from Song Liu which replaces the 'struct module_layout' with a new 'struct module_memory'. The old data structure tried to put together all types of supported module memory types in one data structure, the new one abstracts the differences in memory types in a module to allow each one to provide their own set of details. This paves the way in the future so we can deal with them in a cleaner way. If you look at changes they also provide a nice cleanup of how we handle these different memory areas in a module. This change has been in linux-next since before the merge window opened for v6.3 so to provide more than a full kernel cycle of testing. It's a good thing as quite a bit of fixes have been found for it. Jason Baron then made dynamic debug a first class citizen module user by using module notifier callbacks to allocate / remove module specific dynamic debug information. Nick Alcock has done quite a bit of work cross-tree to remove module license tags from things which cannot possibly be module at my request so to: a) help him with his longer term tooling goals which require a deterministic evaluation if a piece a symbol code could ever be part of a module or not. But quite recently it is has been made clear that tooling is not the only one that would benefit. Disambiguating symbols also helps efforts such as live patching, kprobes and BPF, but for other reasons and R&D on this area is active with no clear solution in sight. b) help us inch closer to the now generally accepted long term goal of automating all the MODULE_LICENSE() tags from SPDX license tags In so far as a) is concerned, although module license tags are a no-op for non-modules, tools which would want create a mapping of possible modules can only rely on the module license tag after the commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"). Nick has been working on this *for years* and AFAICT I was the only one to suggest two alternatives to this approach for tooling. The complexity in one of my suggested approaches lies in that we'd need a possible-obj-m and a could-be-module which would check if the object being built is part of any kconfig build which could ever lead to it being part of a module, and if so define a new define -DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've suggested would be to have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as well but that means getting kconfig symbol names mapping to modules always, and I don't think that's the case today. I am not aware of Nick or anyone exploring either of these options. Quite recently Josh Poimboeuf has pointed out that live patching, kprobes and BPF would benefit from resolving some part of the disambiguation as well but for other reasons. The function granularity KASLR (fgkaslr) patches were mentioned but Joe Lawrence has clarified this effort has been dropped with no clear solution in sight [1]. In the meantime removing module license tags from code which could never be modules is welcomed for both objectives mentioned above. Some developers have also welcomed these changes as it has helped clarify when a module was never possible and they forgot to clean this up, and so you'll see quite a bit of Nick's patches in other pull requests for this merge window. I just picked up the stragglers after rc3. LWN has good coverage on the motivation behind this work [2] and the typical cross-tree issues he ran into along the way. The only concrete blocker issue he ran into was that we should not remove the MODULE_LICENSE() tags from files which have no SPDX tags yet, even if they can never be modules. Nick ended up giving up on his efforts due to having to do this vetting and backlash he ran into from folks who really did *not understand* the core of the issue nor were providing any alternative / guidance. I've gone through his changes and dropped the patches which dropped the module license tags where an SPDX license tag was missing, it only consisted of 11 drivers. To see if a pull request deals with a file which lacks SPDX tags you can just use: ./scripts/spdxcheck.py -f \ $(git diff --name-only commid-id | xargs echo) You'll see a core module file in this pull request for the above, but that's not related to his changes. WE just need to add the SPDX license tag for the kernel/module/kmod.c file in the future but it demonstrates the effectiveness of the script. Most of Nick's changes were spread out through different trees, and I just picked up the slack after rc3 for the last kernel was out. Those changes have been in linux-next for over two weeks. The cleanups, debug code I added and final fix I added for modules were motivated by David Hildenbrand's report of boot failing on a systems with over 400 CPUs when KASAN was enabled due to running out of virtual memory space. Although the functional change only consists of 3 lines in the patch "module: avoid allocation if module is already present and ready", proving that this was the best we can do on the modules side took quite a bit of effort and new debug code. The initial cleanups I did on the modules side of things has been in linux-next since around rc3 of the last kernel, the actual final fix for and debug code however have only been in linux-next for about a week or so but I think it is worth getting that code in for this merge window as it does help fix / prove / evaluate the issues reported with larger number of CPUs. Userspace is not yet fixed as it is taking a bit of time for folks to understand the crux of the issue and find a proper resolution. Worst come to worst, I have a kludge-of-concept [3] of how to make kernel_read*() calls for modules unique / converge them, but I'm currently inclined to just see if userspace can fix this instead" Link: https://lore.kernel.org/all/Y/kXDqW+7d71C4wz@bombadil.infradead.org/ [0] Link: https://lkml.kernel.org/r/025f2151-ce7c-5630-9b90-98742c97ac65@redhat.com [1] Link: https://lwn.net/Articles/927569/ [2] Link: https://lkml.kernel.org/r/20230414052840.1994456-3-mcgrof@kernel.org [3] * tag 'modules-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: (121 commits) module: add debugging auto-load duplicate module support module: stats: fix invalid_mod_bytes typo module: remove use of uninitialized variable len module: fix building stats for 32-bit targets module: stats: include uapi/linux/module.h module: avoid allocation if module is already present and ready module: add debug stats to help identify memory pressure module: extract patient module check into helper modules/kmod: replace implementation with a semaphore Change DEFINE_SEMAPHORE() to take a number argument module: fix kmemleak annotations for non init ELF sections module: Ignore L0 and rename is_arm_mapping_symbol() module: Move is_arm_mapping_symbol() to module_symbol.h module: Sync code of is_arm_mapping_symbol() scripts/gdb: use mem instead of core_layout to get the module address interconnect: remove module-related code interconnect: remove MODULE_LICENSE in non-modules zswap: remove MODULE_LICENSE in non-modules zpool: remove MODULE_LICENSE in non-modules x86/mm/dump_pagetables: remove MODULE_LICENSE in non-modules ...
