2023-03-07platform/x86: amd: pmc: Convert to platform remove callback returning voidUwe Kleine-König1-3/+2
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 (mostly) ignored 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. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

models only When support for instantiating an i2c-client for the fuel-gauge was added for the Windows based Yoga Book YB1-X91F/L models, the assumption was made that this would apply to the Android based YB1-X90F/L models too.

2023-03-07platform/x86: x86-android-tablets: Add backlight ctrl for Lenovo Yoga Tab 3 ↵Hans de Goede1-0/+23
Pro YT3-X90F The YT3 uses an TI LP8557 LED backlight controller, the LP8557's PWM input is connected to a PWM output coming from the LCD panel's controller. The Android kernel has a hack in the i915 driver to write the non-standard DSI reg 0x51 with the desired level to set the duty-cycle of the LCD's PWM. To avoid having to have a similar hack in the mainline kernel program instantiate an i2c-client for the LP8557 with platform-data to have the LP8557 to directly set the level (ignoring its PWM input), this allows backlight brightness control through a backlight device registered by the lp855x_bl driver.

2023-03-07platform/x86: x86-android-tablets: Add support for the Dolby button on Peaq ↵Hans de Goede6-136/+37
C1010 The Peaq C1010 tablet has a special "Dolby" button. This button has a WMI interface, but this is broken in several ways: 1. It only supports polling 2. The value read on polling goes from 0 -> 1 for one poll on both edges of the button, with no way to tell which edge causes the poll to return 1. 3. It uses a non unique GUID (it uses the Microsoft docs WMI example GUID). There currently is a WMI driver for this, but it uses several kludges to work around these issues and is not entirely reliable due to 2. Replace the unreliable WMI driver by using the x86-android-tablets code to instantiate a gpio_keys device for this.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull thermal control updates from Rafael Wysocki: "The majority of changes here are related to the general switch-over to using arrays of generic trip point structures registered along with a thermal zone instead of trip point callbacks (this has been done mostly by Daniel Lezcano with some help from yours truly on the Intel drivers front). Apart from that and the related reorganization of code, there are some enhancements of the existing driver and a new Mediatek Low Voltage Thermal Sensor (LVTS) driver. The Intel powerclamp undergoes a major rework so it will use the generic idle_inject facility for CPU idle time injection going forward and it will take additional module parameters for specifying the subset of CPUs to be affected by it (work done by Srinivas Pandruvada). Also included are assorted fixes and a whole bunch of cleanups.

2023-02-18platform/x86: nvidia-wmi-ec-backlight: Add force module parameterHans de Goede1-1/+5
On some Lenovo Legion models, the backlight might be driven by either one of nvidia_wmi_ec_backlight or amdgpu_bl0 at different times. When the Nvidia WMI EC backlight interface reports the backlight is controlled by the EC, the current backlight handling only registers nvidia_wmi_ec_backlight (and registers no other backlight interfaces). This hides (never registers) the amdgpu_bl0 interface, where as prior to 6.1.4 users would have both nvidia_wmi_ec_backlight and amdgpu_bl0 and could work around things in userspace. Add a force module parameter which can be used with acpi_backlight=native to restore the old behavior as a workound (for now) by passing: "acpi_backlight=native nvidia-wmi-ec-backlight.force=1" Fixes: 8d0ca287fd8c ("platform/x86: nvidia-wmi-ec-backlight: Use acpi_video_get_backlight_type()") Link: https://bugzilla.kernel.org/show_bug.cgi?id=217026 Cc: [email protected] Signed-off-by: Hans de Goede <[email protected]> Reviewed-by: Daniel Dadap <[email protected]> Link: https://lore.kernel.org/r/[email protected]

Thanks to bugreport 216655 on bugzilla triggered by the dell-smm-hwmon driver, the contents of the sensor buffers could be almost completely decoded. Add an hwmon interface for exposing the fan and thermal sensor values. Since the WMI interface can be quite slow on some machines, the sensor buffers are cached for 1 second to lessen the performance impact. The debugfs interface remains in place to aid in reverse-engineering of unknown sensor types and the thermal buffer.

configuration Currently hotplug configuration in logic device assumes that all items are provided with no holes. Thus, any group of hotplug events, associated with the specific status/event/mask registers is configured in those registers successively from bit zero to bit #n (#n < 8). This logic is changed int order to allow non-successive definition to support configuration with the skipped bits – for example bits 3, 5, 7 in status/event/mask registers can be associated with hotplug events, while others can be skipped.

2023-02-13platform: mellanox: Split logic in init and exit flowVadim Pasternak1-109/+204
Split logic in mlxplat_init()/mlxplat_exit() routines. Separate initialization of I2C infrastructure and others platform drivers. Motivation is to provide synchronization between I2C bus and mux drivers and other drivers using this infrastructure. I2C main bus and MUX busses are implemented in FPGA logic. On some new systems the numbers allocated for these busses could be variable depending on order of initialization of I2C native busses. Since bus numbers are passed to some other platform drivers during initialization flow, it is necessary to synchronize completion of I2C infrastructure drivers and activation of rest of drivers. Thus initialization flow will be performed in synchronized order.
