platform/x86: sony-laptop: Make resuming thermal profile safer

2020-06-17T14:42:08+00:00

commit 476d60b1b4c8a2b14a53ef9b772058f35e604661 upstream.

The thermal handle object may fail initialization when the module is
loaded in the first place. Avoid attempting to use it on resume then.

platform/x86: sony-laptop: SNC calls should handle BUFFER types

2020-06-17T14:42:08+00:00

commit 47828d22539f76c8c9dcf2a55f18ea3a8039d8ef upstream.

After commit 6d232b29cfce ("ACPICA: Dispatcher: always generate buffer
objects for ASL create_field() operator") ACPICA creates buffers even
when new fields are small enough to fit into an integer.
Many SNC calls counted on the old behaviour.
Since sony-laptop already handles the INTEGER/BUFFER case in
sony_nc_buffer_call, switch sony_nc_int_call to use its more generic
function instead.

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

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

proc: convert everything to "struct proc_ops"

2020-02-04T03:05:26+00:00

The most notable change is DEFINE_SHOW_ATTRIBUTE macro split in
seq_file.h.

Conversion rule is:

	llseek		=> proc_lseek
	unlocked_ioctl	=> proc_ioctl

	xxx		=> proc_xxx

	delete ".owner = THIS_MODULE" line

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.
