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

2020-04-17T14:12:05Z

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()

2020-04-13T11:16:39Z

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

2020-04-02T13:09:52Z

commit 95b31e35239e5e1689e3d965d692a313c71bd8ab upstream. The Lex 2I385SW board has two Intel I211 ethernet controllers. Without this patch, only the first port is usable. The second port fails to start with the following message: igb: probe of 0000:02:00.0 failed with error -2 Fixes: 648e921888ad ("clk: x86: Stop marking clocks as CLK_IS_CRITICAL") Tested-by: Georg Müller Signed-off-by: Georg Müller Reviewed-by: Hans de Goede Signed-off-by: Andy Shevchenko Signed-off-by: Greg Kroah-Hartman

platform/x86: intel_mid_powerbtn: Take a copy of ddata

2020-02-14T21:53:01Z

commit 5e0c94d3aeeecc68c573033f08d9678fecf253bd upstream. The driver gets driver_data from memory that is marked as const (which is probably put to read-only memory) and it then modifies it. This likely causes some sort of fault to happen. Fix this by taking a copy of the structure.

platform/x86: intel_scu_ipc: Fix interrupt support

2020-02-11T12:36:45Z

commit e48b72a568bbd641c91dad354138d3c17d03ee6f upstream. Currently the driver has disabled interrupt support for Tangier but actually interrupt works just fine if the command is not written twice in a row. Also we need to ack the interrupt in the handler.

platform/x86: asus-wmi: Fix keyboard brightness cannot be set to 0

2020-01-13T09:50:59Z

Some of ASUS laptops like UX431FL keyboard backlight cannot be set to brightness 0. According to ASUS' information, the brightness should be 0x80 ~ 0x83. This patch fixes it by following the logic.

platform/x86: GPD pocket fan: Allow somewhat lower/higher temperature limits

2020-01-13T09:37:50Z

Allow the user to configure the fan to turn on / speed-up at lower thresholds then before (20 degrees Celcius as minimum instead of 40) and likewise also allow the user to delay the fan speeding-up till the temperature hits 90 degrees Celcius (was 70).

platform/x86: GPD pocket fan: Use default values when wrong modparams are given

2020-01-13T09:37:50Z

Use our default values when wrong module-parameters are given, instead of refusing to load. Refusing to load leaves the fan at the BIOS default setting, which is "Off". The CPU's thermal throttling should protect the system from damage, but not-loading is really not the best fallback in this case. This commit fixes this by re-setting module-parameter values to their defaults if they are out of range, instead of failing the probe with -EINVAL.
