Add support for ASIC hotplug device events for the all system types. The ASIC hotplug event is sent in cases ASIC reaches the good health state or dropped to the bad health state. The health state is used to change, when device is reset or in case of some system failures. In such cases hwmon uevent notification will be sent. Signed-off-by:

Simplify the logic of ASIC health discovery. ASIC device can indicate its health state as a good, booting or dormant. During ASIC reset the device is dropped to dormant state and should get to the stable good health state through the intermediate booting state. The sequence for getting to the steady state health after reset is: (dormant -> booting -> good)+. Initial implementation assumes that ?good? within this sequence is always repeated twice and device is getting steady state only after the second ?good?. This patch removes this dependency, since the second ?good? is received because of the noise on line and can be ignored. Device reaches steady state after the first ?good? is received. Signed-off-by:

Add mlxreg-fan platform driver activation. FAN driver uses the same regmap infrastructure as others Mellanox platform drivers. Specific registers description for default FAN platform data configuration are added to mlx-platform. There are the registers for tachometers reading, PWM control and FAN ownership control. The last one has a default value, which is set at initialization time through the regmap infrastructure, which is necessary for moving FAN control ownership from hardware to software. Signed-off-by:

Fix return code check for "max brightness" ACPI call. The Dell laptop ACPI video brightness control is not present on dell laptops anymore, but was present in older kernel versions. The code that checks the return value is incorrect since the SMM refactoring. The old code was: if (buffer->output[0] == 0) Which was changed to: ret = dell_send_request(...) if (ret) However, dell_send_request() will return 0 if buffer->output[0] == 0, so we must change the check to: if (ret == 0) This issue was found on a Dell M4800 laptop, and the fix tested on it as well.

The Dell laptop I have has an ACPI that sends 0xCB and 0xCC on entering tablet mode. On exiting tablet mode it sends 0xCA and 0xCD. Based on: http://www.traby.de/medion/DSDT/dsdt.dsl https://gist.github.com/jprvita/5737de3cbb670e80973b7d4e51c38ab6 https://osdn.net/projects/android-x86/scm/git/kernel/commits/ 7cbe5a330687b851f32dd9f1048a6ce182d0ff44 It appears that 0xCA and 0xCB are about dock mode, which for my convertible laptop seems questionably tied to whether I've put the laptop in tablet or laptop mode. I previously proposed no-oping 0xCA and 0xCB but this revised change attempts to add support for detecting dock mode--this detection will essentially be broken for my laptop (the main workaround would be for 0xCA and 0xCB to be used to provoke a query of the VGBS method that reports the current dock & tablet mode [which is accurately reported on my laptop but based on the prior workarounds in the driver it apparently can't be trusted for all systems]).

In some of the recent platforms, it is possible that stand alone methods for HEBC() or other methods used in this driver may not exist. In this case intel-hid driver will fail to load and power button will not be functional. It is also possible that some quirks in this driver added for some platforms may have same issue in loading intel-hid driver. There is an update to the ACPI details for the HID event filter driver. In the updated specification a _DSM is added, which has separate function indexes for each of the previous stand alone methods. This change brings in support for the _DSM and allows usage of function index for corresponding stand alone methods. Details of Device Specific Method: Intel HID Event Filter Driver _DSM UUID: eeec56b3-4442-408f-a792-4edd4d758054 • Function index 0: Returns a buffer with a bit-field representing the supported function IDs. Function Index ASL Object -------------------------------- 1 BTNL 2 HDMM 3 HDSM 4 HDEM 5 BTNS 6 BTNE 7 HEBC 8 VGBS 9 HEBC One significant change is to query the supported methods implemented on the platform. So the previous HEBC() has two variants. HEBC v1 and HEBC v2. The v2 version allowed further define which of the 5-button are actually defined by the platform. HEBC v2 support is only available via new DSM. v1 Button details: Bits [0] - Rotation Lock, Num Lock, Home, End, Page Up, Page Down Bits [1] - Wireless Radio Control Bits [2] - System Power Down Bits [3] - System Hibernate Bits [4] - System Sleep/ System Wake Bits [5] - Scan Next Track Bits [6] - Scan Previous Track Bits [7] - Stop Bits [8] - Play/Pause Bits [9] - Mute Bits [10] - Volume Increment Bits [11] - Volume Decrement Bits [12] - Display Brightness Increment Bits [13] - Display Brightness Decrement Bits [14] - Lock Tablet Bits [15] - Release Tablet Bits [16] - Toggle Bezel Bits [17] - 5 button array Bits [18-31] - reserved v2 Buttom details: Bits [0-16] - Same as v1 version Bits [17] - 5 button array Bits [18] – Power Button Bits [19] - W Home Button Bits [20] - Volume Up Button Bits [21] - Volume Down Button Bits [22] – Rotation Lock Button Bits [23-31] – reserved Signed-off-by:

Some ASUS laptops like UX550GE has hotkey (Fn+F7) for keyboard backlight toggle which would emit the scan code 0xc7 each keypress. On the UX550GE, the max keyboard brightness level is 3 so the toggle would not be simply on/off the led but need to be cyclic. Per ASUS spec, it should increment the brightness for each keypress, then toggle(off) the LED when it already reached the max level. Signed-off-by:

Make asus-wmi notify on hotkey kbd brightness changes, listen for brightness events and update the brightness directly in the driver. Create new do_kbd_led_set function for in-driver update, and leave kbd_led_set for original led_classdev call path. Update the brightness by led_classdev_notify_brightness_hw_changed. This will allow userspace to monitor (poll) for brightness changes on the LED without reporting via input keymapping. Signed-off-by:

Adds debugfs access to registers in the Cannon Point PCH PMC that are useful for debugging #SLP_S0 signal assertion and other low power relate activities. Device pm states are latched in these registers whenever the package enters C10 and can be read from slp_s0_debug_status. The pm states may also be latched by writing 1 to slp_s0_dbg_latch which will immediately capture the current state on the next read of slp_s0_debug_status. Signed-off-by:

Not only silead touchscreens need some extra info not available in the ACPI tables to work properly. X86 devices with a Chipone ICN8505 chip also need some DMI based extra configuration. There is no reason to have separate dmi config code per touchscreen controller vendor. This commit renames silead_dmi to a more generic touchscreen_dmi name (and Kconfig option) in preparation of adding info for tablets with an ICN8505 based touchscreen. Note there are no functional changes all code changes are limited to removing references to silead where these are no longer applicable. Acked-by:

Second generation keyboard backlight (type 2) laptops can switch on the keyboard LED on their own via hardware/firmware, but the LED subsystem is unaware of such change since the LED interface was only being created on first generation keyboard backlight (type 1) laptops. This patch creates the LED interface for second gen keyboards and calls the *_hw_changed API whenever userspace changes the state of the keyboard backlight LED. While we are at it, remove an unneeded asignment to the acpi_dev struct under *_kbd_bl_work, and also update the kbd_event_generated variable in the main toshiba struct instead of the global struct.
