2024-03-12drivers/gpio/nomadik: move dummy nmk_gpio_dbg_show_one() to headerMax Kellermann
When `CONFIG_DEBUG_FS` is disabled, nmk_gpio_dbg_show_one() is an empty dummy function; this however triggers a `-Wmissing-prototypes` warning and later a linker error because the function is also used by drivers/pinctrl/nomadik/pinctrl-nomadik.c, therefore it needs to be non-static. To allow both sources to access this dummy function, this patch moves it to the header, adding the `#ifdef CONFIG_DEBUG_FS` there as well.

2024-03-12platform/x86/intel/pmc: Improve PKGC residency counters debugKane Chen
The current code only prints PKGC-10 residency when the PKGC-10 is not reached in previous 'freeze' attempt. To debug PKGC-10 issues, we also need to know other PKGC residency counters to better triage issues. Ex: 1. When system is stuck in PC2, it can be caused short LTR from device. 2. When system is stuck in PC8, it can be caused by display engine. To better triage issues, all PKGC residency are needed when issues happen. Example log: CPU did not enter Package C10!!! (Package C10 cnt=0x0) Prev Package C2 cnt = 0x2191a325de, Current Package C2 cnt = 0x21aba30724 Prev Package C3 cnt = 0x0, Current Package C3 cnt = 0x0 Prev Package C6 cnt = 0x0, Current Package C6 cnt = 0x0 Prev Package C7 cnt = 0x0, Current Package C7 cnt = 0x0 Prev Package C8 cnt = 0x0, Current Package C8 cnt = 0x0 Prev Package C9 cnt = 0x0, Current Package C9 cnt = 0x0 Prev Package C10 cnt = 0x0, Current Package C10 cnt = 0x0 With this log, we can know whether it's a stuck PC2 issue, and we can check whether the short LTR from device causes the issue.

AAEON PICO-TGU4 board doesn't have any LED but there are bogus LED controls under /sys/class/leds: $ ls /sys/class/leds asus::kbd_backlight asus::lightbar platform::micmute The reason is that the ~0 read from asus_wmi_get_devstate() is treated as a valid state, in truth it means the device is absent.

2024-03-12i2c: nomadik: support Mobileye EyeQ5 I2C controllerThéo Lebrun
Add compatible for the integration of the same DB8500 IP block into the Mobileye EyeQ5 platform. Two quirks are present: - The memory bus only supports 32-bit accesses. Avoid writeb() and readb() by introducing helper functions that fallback to writel() and readl(). - A register must be configured for the I2C speed mode; it is located in a shared register region called OLB. We access that memory region using a syscon & regmap that gets passed as a phandle (mobileye,olb). A two-bit enum per controller is written into the register; that requires us to know the global index of the I2C controller (cell arg to the mobileye,olb phandle). We add #include <linux/mfd/syscon.h> and <linux/regmap.h>.

2024-03-12i2c: nomadik: support short xfer timeouts using waitqueue & hrtimerThéo Lebrun
Replace the completion by a waitqueue for synchronization from IRQ handler to task. For short timeouts, use hrtimers, else use timers. Usecase: avoid blocking the I2C bus for too long when an issue occurs. The threshold picked is one jiffy: if timeout is below that, use hrtimers. This threshold is NOT configurable. Implement behavior but do NOT change fetching of timeout. This means the timeout is unchanged (200ms) and the hrtimer case will never trigger. A waitqueue is used because it supports both desired timeout approaches. See wait_event_timeout() and wait_event_hrtimeout(). An atomic boolean serves as synchronization condition.

2024-03-12platform/x86: pmc_atom: Check state of PMC managed devices on s2idleJohannes Stezenbach
For the Bay Trail or Cherry Trail SoC to enter the S0i3 power-level at s2idle suspend requires most of the hw-blocks / devices in the SoC to be in D3 when entering s2idle suspend. If some devices are not in D3 then the SoC will stay in a higher power state, consuming much more power from the battery then in S0i3. Use the new acpi_s2idle_dev_ops and acpi_register_lps0_dev() functionality to register a new s2idle check function which checks that all hardware blocks in the South complex (controlled by the PMC) are in a state that allows the SoC to enter S0i3 and prints an error message for any device in D0. Some blocks are not used on lower-featured versions of the SoC and these blocks will always report being in D0 on SoCs were they are not used. A false-positive mask is used to identify these blocks and for blocks in this mask the error is turned into a debug message to avoid false-positive error messages. Note the pmc_atom code is enabled by CONFIG_X86_INTEL_LPSS which already depends on ACPI.

2024-03-12platform/x86: ISST: Allow reading core-power state on HWP disabled systemsSrinivas Pandruvada
When HWP (Hardware P-states) is disabled, dynamic SST features are disabled. But user should still be able to read the current core-power state, with legacy P-states. This will allow users to read current configuration with static SST enabled from BIOS. To address this, do not call disable_dynamic_sst_features() when the request is for reading the state.

The whitelist-based approach for preventing older WMI drivers from being instantiated multiple times has many drawbacks: - uses cannot see all available WMI devices (if not whitelisted) - whitelisting a WMI driver requires changes in the WMI driver core - maintenance burden for driver and subsystem developers Since the WMI driver core already takes care that older WMI drivers are not being instantiated multiple times, remove the now redundant whitelist.

2024-03-12platform/x86: wmi: Do not instantiate older WMI drivers multiple timesArmin Wolf
Many older WMI drivers cannot be instantiated multiple times for two reasons: - they are using the legacy GUID-based WMI API - they are singletons (with global state) Prevent such WMI drivers from binding to WMI devices with a duplicated GUID, as this would mean that the WMI driver will be instantiated at least two times (one for the original GUID and one for the duplicated GUID). WMI drivers which can be instantiated multiple times can signal this by setting a flag inside struct wmi_driver. Tested on a ASUS Prime B650-Plus.

git://git.kernel.org/pub/scm/linux/kernel/git/andi.shyti/linux into i2c/for-mergewindow The i801 and designware drivers received most of the changes, including refactorings and some additions. Recovery changes for the iMX and iMX-LPI2C are now utilizing the generic i2c support. The Cadence driver now supports system suspend and resume. The hisi, mpc, sh_mobile, and npcm drivers have undergone some cleanups and improvements. Meanwhile, Uwe continues his work on converting the "remove" callback to become a void function. The pca954x mux driver now supports additional configurations, such as isolating faulty channels and flushing stuck buses, among others. Support has been added for Renesas r8a779h0, i.MX95 LPI2C, and Microchip sam9x7. Meanwhile, Geert lays the groundwork for the upcoming R-Car Gen4.
2024-03-12hv: vmbus: Convert to platform remove callback returning voidUwe Kleine-König
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.
