platform/x86: asus-nb-wmi: Do not load on Asus T100TA and T200TA

2020-05-27T15:48:11+00:00

[ Upstream commit 3bd12da7f50b8bc191fcb3bab1f55c582234df59 ] asus-nb-wmi does not add any extra functionality on these Asus Transformer books. They have detachable keyboards, so the hotkeys are send through a HID device (and handled by the hid-asus driver) and also the rfkill functionality is not used on these devices. Besides not adding any extra functionality, initializing the WMI interface on these devices actually has a negative side-effect. For some reason the \_SB.ATKD.INIT() function which asus_wmi_platform_init() calls drives GPO2 (INT33FC:02) pin 8, which is connected to the front facing webcam LED, high and there is no (WMI or other) interface to drive this low again causing the LED to be permanently on, even during suspend. This commit adds a blacklist of DMI system_ids on which not to load the asus-nb-wmi and adds these Transformer books to this list. This fixes the webcam LED being permanently on under Linux.

platform/x86: GPD pocket fan: Fix error message when temp-limits are out of range

2020-05-10T08:32:52+00:00

commit 1d6f8c5bac93cceb2d4ac8e6331050652004d802 upstream. Commit 1f27dbd8265d ("platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits") changed the module-param sanity check to accept temperature limits between 20 and 90 degrees celcius. But the error message printed when the module params are outside this range was not updated. This commit updates the error message to match the new min and max value for the temp-limits.

platform/x86: intel-hid: fix: Update Tiger Lake ACPI device ID

2020-04-23T08:38:12+00:00

[ Upstream commit d5764dc597467664a1a70ab66a2314a011aeccd4 ] Tiger Lake's new unique ACPI device IDs for intel-hid driver is not valid because of missing 'C' in the ID. Fix the ID by updating it. After the update, the new ID should now look like INT1051 --> INTC1051 Fixes: bdd11b654035 ("platform/x86: intel-hid: Add Tiger Lake ACPI device ID") Suggested-by: Srinivas Pandruvada Signed-off-by: Gayatri Kammela Reviewed-by: Andy Shevchenko Signed-off-by: Rafael J.

platform/x86: asus-wmi: Support laptops where the first battery is named BATT

2020-04-17T14:13:32+00:00

commit 6b3586d45bba14f6912f37488090c37a3710e7b4 upstream. The WMI method to set the charge threshold does not provide a way to specific a battery, so we assume it is the first/primary battery (by checking if the name is BAT0). On some newer ASUS laptops (Zenbook UM431DA) though, the primary/first battery isn't named BAT0 but BATT, so we need to support that case.

platform/x86: intel_int0002_vgpio: Use acpi_register_wakeup_handler()

2020-04-13T11:17:58+00:00

commit 767191db8220db29f78c031f4d27375173c336d5 upstream. The Power Management Events (PMEs) the INT0002 driver listens for get signalled by the Power Management Controller (PMC) using the same IRQ as used for the ACPI SCI. Since commit fdde0ff8590b ("ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system") the SCI triggering, without there being a wakeup cause recognized by the ACPI sleep code, will no longer wakeup the system. This breaks PMEs / wakeups signalled to the INT0002 driver, the system never leaves the s2idle_loop() now. Use acpi_register_wakeup_handler() to register a function which checks the GPE0a_STS register for a PME and trigger a wakeup when a PME has been signalled.

platform/x86: pmc_atom: Add Lex 2I385SW to critclk_systems DMI table

commit 95b31e35239e5e1689e3d965d692a313c71bd8ab upstream. The Lex 2I385SW board has two Intel I211 ethernet controllers. Without this patch, only the first port is usable.

platform/x86: intel_menlow: switch to use helpers

2020-01-31T18:30:40+00:00

This switches the intel_menlow driver to use deci_kelvin_to_celsius() and celsius_to_deci_kelvin() in instead of helpers in . This is preparation for centralizing the kelvin to/from Celsius conversion helpers in . This also removes a trailing space, while we're at it.

platform/x86: asus-wmi: switch to use helpers

2020-01-31T18:30:40+00:00

The asus-wmi driver doesn't implement the thermal device functionality directly, so including just for DECI_KELVIN_TO_CELSIUS() is a bit odd. This switches the asus-wmi driver to use deci_kelvin_to_millicelsius() in . The format string is changed from %d to %ld due to function returned type.
