thermal: int340x: Add keep alive response method

2020-10-12T10:08:36+00:00

When firmware requests keep alive response, send an event to user space
to confirm by using imok sysfs entry.

Create a new sysf entry called "imok". User space can write an integer,
which results in execution of IMOK ACPI method of INT3400 thermal zone
device. This results in sending response to firmware request for keep
alive.

thermal: int340x: Provide notification for OEM variable change

2020-10-12T10:08:35+00:00

When we receive ACPI notification for OEM variable change pass the
notification to user space handler. This will avoid polling for
OEM variable change from user space.

Merge tag 'sched-fifo-2020-08-04' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2020-08-06T18:55:43+00:00

Pull sched/fifo updates from Ingo Molnar:
 "This adds the sched_set_fifo*() encapsulation APIs to remove static
  priority level knowledge from non-scheduler code.

  The three APIs for non-scheduler code to set SCHED_FIFO are:

   - sched_set_fifo()
   - sched_set_fifo_low()
   - sched_set_normal()

  These are two FIFO priority levels: default (high), and a 'low'
  priority level, plus sched_set_normal() to set the policy back to
  non-SCHED_FIFO.

  Since the changes affect a lot of non-scheduler code, we kept this in
  a separate tree"

thermal/int340x_thermal: Prevent page fault on .set_mode() op

2020-07-14T14:46:44+00:00

Starting from commit "thermal/int340x_thermal: Don't require IDSP to
exist", priv->current_uuid_index is initialized to -1. This value may
be passed to int3400_thermal_run_osc() from int3400_thermal_set_mode,
contributing to page fault when accessing int3400_thermal_uuids array
at index -1.

This commit adds a check on uuid value to int3400_thermal_run_osc.

thermal: Rename set_mode() to change_mode()

2020-06-29T18:26:39+00:00

set_mode() is only called when tzd's mode is about to change. Actual
setting is performed in thermal_core, in thermal_zone_device_set_mode().
The meaning of set_mode() callback is actually to notify the driver about
the mode being changed and giving the driver a chance to oppose such
change.

To better reflect the purpose of the method rename it to change_mode()

thermal: Simplify or eliminate unnecessary set_mode() methods

2020-06-29T18:26:39+00:00

Setting polling_delay is now done at thermal_core level (by not polling
DISABLED devices), so no need to repeat this code.

int340x: Checking for an impossible enum value is unnecessary.
acpi/thermal: It only prints debug messages.
