thermal: core: Fix TZ_GET_TRIP NULL pointer dereference

2022-03-01T15:11:38+00:00

Do not call get_trip_hyst() from thermal_genl_cmd_tz_get_trip() if
the thermal zone does not define one.

thermal: int340x: fix memory leak in int3400_notify()

Pull thermal control updates from Rafael Wysocki:
 "These add a new driver for Renesas RZ/G2L TSU, update a few existing
  thermal control drivers and clean up the tmon utility.

  Specifics:

   - Add new TSU driver and DT bindings for the Renesas RZ/G2L platform
     (Biju Das).

   - Fix missing check when calling reset_control_deassert() in the
     rz2gl thermal driver (Biju Das).

   - In preparation for FORTIFY_SOURCE performing compile-time and
     run-time field bounds checking for memcpy(), avoid intentionally
     writing across neighboring fields in the int340x thermal control
     driver (Kees Cook).

   - Fix RFIM mailbox write commands handling in the int340x thermal
     control driver (Sumeet Pawnikar).

   - Fix PM issue occurring in the iMX thermal control driver during
     suspend/resume by implementing PM runtime support in it (Oleksij
     Rempel).

   - Add 'const' annotation to thermal_cooling_ops in the Intel
     powerclamp driver (Rikard Falkeborn).

   - Fix missing ADC bit set in the iMX8MP thermal driver to enable the
     sensor (Paul Gerber).

   - Drop unused local variable definition from tmon (ran jianping)"

thermal/drivers/int340x: Fix RFIM mailbox write commands

2021-12-30T15:42:53+00:00

The existing mail mechanism only supports writing of workload types.

However, mailbox command for RFIM (cmd = 0x08) also requires write
operation which is ignored. This results in failing to store RFI
restriction.

Fixint this requires enhancing mailbox writes for non workload
commands too, so remove the check for MBOX_CMD_WORKLOAD_TYPE_WRITE
in mailbox write to allow this other write commands to be supoorted.

At the same time, however, we have to make sure that there is no
impact on read commands, by avoiding to write anything into the
mailbox data register.

To properly implement that, add two separate functions for mbox read
and write commands for the processor thermal workload command type.
This helps to distinguish the read and write workload command types
from each other while sending mbox commands.
