[PATCH 0/8 v2] enable to use thermal-zone on r8a7790/1

[PATCH 0/8 v2] enable to use thermal-zone on r8a7790/1

[Kuninori Morimoto]

Hi

These are v2 of thermal-zone support for r8a7790/r8a7791.
Mainly, it cares return value of get_temp()

I think 8) is needed on of-thermal (?)

Kuninori Morimoto (8):
      1) thermal: rcar: move rcar_thermal_dt_ids to upside
      2) thermal: rcar: check every rcar_thermal_update_temp() return value
      3) thermal: rcar: check irq possibility in rcar_thermal_irq_xxx()
      4) thermal: rcar: retern error rcar_thermal_get_temp() if no ctemp update
      5) thermal: rcar: enable to use thermal-zone on DT
      6) ARM: shmobile: r8a7790: enable to use thermal-zone
      7) ARM: shmobile: r8a7791: enable to use thermal-zone
      8) thermal: of-thermal: of_thermal_set_trip_temp() call thermal_zone_device_update()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rcar thermal driver sometimes checks irq possibility when it
calls rcar_thermal_irq_enable/disable(), but sometimes not.
This patch checks it inside rcar_thermal_irq_enable/disable().

[PATCH 4/8 v2] thermal: rcar: retern error rcar_thermal_get_temp() if no ctemp update

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

Current rcar_thermal_get_temp() returns latest temperature, but it might
not be updated if some HW issue happend. This means user might get
wrong temperature. This patch solved this issue.

[PATCH 6/8 v2] ARM: shmobile: r8a7790: enable to use thermal-zone

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

This patch enables to use thermal-zone on r8a7790.
This thermal sensor can measure temperature from -40000 to 125000,
but over 117000 can be critical on this chip.
Thus, default critical temperature is now set as 115000 (this driver
is using 5000 steps) (Current critical temperature is using it as
90000, but there is no big reason about it)

And it doesn't check thermal zone periodically (same as current
behavior). You can exchange it by modifing polling-delay[-passive]
property.

You can set trip temp if your kernel has CONFIG_THERMAL_WRITABLE_TRIPS,
but you need to take care to use it, since it will call
orderly_poweroff() it it reached to the value.

[PATCH 8/8 v2] thermal: of-thermal: of_thermal_set_trip_temp() call thermal_zone_device_update()

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com>

of_thermal_set_trip_temp() updates trip temperature. It should call
thermal_zone_device_update() immediately.
