2023-12-20pwm: Make it possible to apply PWM changes in atomic contextSean Young1-0/+9
Some PWM devices require sleeping, for example if the pwm device is connected over I2C. However, many PWM devices could be used from atomic context, e.g. memory mapped PWM. This is useful for, for example, the pwm-ir-tx driver which requires precise timing. Sleeping causes havoc with the generated IR signal. Since not all PWM devices can support atomic context, we also add a pwm_might_sleep() function to check if is not supported.

2023-11-23arch/*/io.h: remove ioremap_uc in some architecturesBaoquan He1-4/+5
ioremap_uc() is only meaningful on old x86-32 systems with the PAT extension, and on ia64 with its slightly unconventional ioremap() behavior. So remove the ioremap_uc() definition in architecutures other than x86 and ia64. These architectures all have asm-generic/io.h included and will have the default ioremap_uc() definition which returns NULL. This changes the existing behaviour, while no need to worry about any breakage because in the only callsite of ioremap_uc(), code has been adjusted to eliminate the impact. Please see atyfb_setup_generic() of drivers/video/fbdev/aty/atyfb_base.c. If any new invocation of ioremap_uc() need be added, please consider using ioremap() intead or adding a ARCH specific version if necessary.

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "We don't have any new drivers. The loongson driver is getting extended with support for new models. There's a big refactor of gpio-pca953x and many small improvements to others. The GPIO code in the kernel has acquired a lot of cruft over the years as well as many abusers of the API across the kernel tree. This release cycle we have started a major cleanup and improvement effort that will most likely span several releases. We have started by converting external users of struct gpio_chip to accessing the wrapper around it - struct gpio_device. This is because the latter is reference counted while the former is removed when the provider is unbound. We also removed several instances of drivers accessing private GPIOLIB structures and including the private header from drivers/gpio/. To that end you'll see several commits aimed at different subsystems (acked by relevant maintainers) as well as two merges from the x86/platform tree. We'll then rework the locking in GPIOLIB which currently uses a big spinlock for many different things and could use becoming more fine-grained, especially as it doesn't even get the locking right. We'll also use SRCU for protecting the gpio_chip pointer against in-kernel hot-unplug crashes similar to what we saw triggered from user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB is still vulnerable to these use-cases. I'm just mentioning the plans here, this is not part of this PR. You'll see some new instances of using __free(). We've added a gpio_device_put cleanup helper similar to the put_device one introduced by Peter Zijlstra and used it according to the preferred pattern except where it didn't make sense. GPIOLIB core: - provide interfaces allowing users to retrieve, manage and query the reference counted GPIO device instead of accessing the private gpio_chip structure - replace gpiochip_find() with gpio_device_find() - remove unused acpi_get_and_request_gpiod() - improve the ignore_interrupt functionality in GPIO ACPI - correct notifier return codes in gpiolib-of - unexport gpiod_set_transitory() as it's unused outside of core GPIO code - while there are still external users accessing struct gpio_chip, let's make gpiochip_get_desc() public so that they at least use the preferred helper - improve locking for lookup tables - annotate struct linereq with __counted_by - improve GPIOLIB docs - add an OF quirk for LED trigger sources Driver improvements: - convert all GPIO drivers with .remove() callbacks to using the new variant returning void instead of int - stop accessing the GPIOLIB private structures in gpio-mockup, i2c-mux-gpio, hte-tegra194, gpio-sim - use the recommended pattern for autofree variables in gpio-sim - add support for more models to gpio-loongson - use a notifier chain to notify other blocks about interrupts in gpio-eic-sprd instead of looking up GPIO devices on every interrupt - convert gpio-pca953x and gpio-fx6408 to using the maple tree regmap cache - don't include GPIOLIB internal headers in drivers which don't need them - move the ingenic NAND quirk into gpiolib-of - add an ignore interrupt quirk for Peaq C1010 - drop static GPIO base from gpio-omap, gpio-f7188x - use the preferred device_get_match_data() function in drivers that still don't - refactor gpio-pca953x: switch to using DEFINE_SIMPLE_DEV_PM_OPS(), use cleanup helpers, use dev_err_probe() where it makes sense, fully convert to using devres and some other minor tweaks DT bindings: - add support for a new model to gpio-vf610 and update existing properties - add support for more loongson models - add missing support for imx models that are used but undocumented - convert bindings for Intel IXP4xx to schema Minor stuff: - deprecate gpio-mockup in favor of gpio-sim - include missing headers here and there - stop using gpiochip_find() in OMAP1 board files - minor tweaks in gpio-vf610, gpio-hisi - remove unneeded 'extern' specifiers from headers" * tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (108 commits) hte: tegra194: add GPIOLIB dependency hte: tegra194: don't access struct gpio_chip gpiolib: provide gpio_device_get_base() i2c: mux: gpio: don't fiddle with GPIOLIB internals gpiolib: provide gpiod_to_gpio_device() gpiolib: provide gpio_device_to_device() gpio: hisi: Fix format specifier gpiolib: provide gpio_device_find_by_fwnode() gpio: acpi: remove acpi_get_and_request_gpiod() gpio: Use device_get_match_data() gpio: vf610: update comment for i.MX8ULP and i.MX93 legacy compatibles platform/x86: int3472: Switch to devm_get_gpiod() platform/x86: int3472: Stop using gpiod_toggle_active_low() platform/x86: int3472: Add new skl_int3472_gpiod_get_from_temp_lookup() helper platform/x86: int3472: Add new skl_int3472_fill_gpiod_lookup() helper gpio: vf610: simplify code by dropping data check gpio: vf610: add i.MX8ULP of_device_id entry dt-bindings: gpio: vf610: add i.MX95 compatible dt-bindings: gpio: vf610: correct i.MX8ULP and i.MX93 dt-bindings: gpio: vf610: update gpio-ranges ...

make htmldocs warns: Documentation/driver-api/80211/mac80211:109: ./include/net/mac80211.h:5170: WARNING: Duplicate C declaration, also defined at mac80211:1117. Declaration is '.. c:function:: void ieee80211_tx_status (struct ieee80211_hw *hw, struct sk_buff *skb)'. This is because there's a function named ieee80211_tx_status() and a struct named ieee80211_tx_status. This has been discussed previously but no solution found: https://lore.kernel.org/all/20220521114629.6ee9fc06@coco.lan/ There's also a bug open for three years with no solution in sight: https://github.com/sphinx-doc/sphinx/pull/8313 So I guess we have no other solution than to a workaround this in the code, for example to rename the function to ieee80211_tx_status_skb() to avoid the name conflict. I got the idea for the name from ieee80211_tx_status_noskb() in which the skb is not provided as an argument, instead with ieee80211_tx_status_skb() the skb is provided. Compile tested only.

2023-10-12thermal: int340x: processor_thermal: Support power floor notificationsSrinivas Pandruvada1-0/+10
When the hardware reduces the power to the minimum possible, the power floor is notified via an interrupt. This can happen when user space requests a power limit via powercap RAPL interface, which forces the system to enter to the lowest power. This power floor indication can be used as a hint to resort to other methods of reducing power than via RAPL power limit. Before power floor status can be read or the firmware can trigger notifications regarding it, it needs to be configured via a mailbox command. The actual power floor status is read via bit 39 of MMIO offset 0x5B18 of the processor thermal PCI device. To show the current power floor status and get notification on a sysfs attribute, add 2 new attributes to /sys/bus/pci/devices/0000\:00\:04.0/power_limits/ power_floor_enable : This attribute is present when power floor notifications are supported. This attribute allows to enable/disable power floor notifications. power_floor_status : This attribute is present when power floor notifications are supported. When enabled via power_floor_enable, this attribute shows the current power floor status. The power floor implementation provides interfaces which are called from the sysfs callbacks to enable/disable and read power floor status. It also provides two additional interfaces to check if the current processor thermal device interrupt is for power floor status and to send notifications to user space.

Camera sensor drivers are highly subject to cargo cult programming, with back practices being copied from old to new drivers. In particular, many drivers implement system and runtime PM incorrectly. As a first step towards fixing this situation, refactor and expand the power management documentation to detail correct usage of system and runtime PM.
