[PATCH v2 0/6] Backlight support for the Armadillo 800 EVA board

[PATCH v2 0/6] Backlight support for the Armadillo 800 EVA board

[Laurent Pinchart]

Hi everybody,

Here's the second version of the Armadillo 800 EVA board backlight support
patches. The backlight is driven by a PWM signal generated by the TPU, so
the bulk of the patch set consists of a TPU PWM driver. The last two patches
remove the LED-specific leds-renesas-tpu driver and make the Kota2 board use
the new rmob-tpu-pwm driver with leds-pwm.

The patches have been tested with the Armadillo EVA 800 board. The Kota2
patches have only been compile-tested.

Changes since v1:

- Add an RMOB_TPU_PWM_ID macro to compute PWM IDs based on the number of
  channels per TPU.

Laurent Pinchart (6):
  ARM: mach-shmobile: clock-r8a7740: add TPU PWM support
  misc: Add Renesas Mobile TPU PWM driver
  ARM: mach-shmobile: armadillo800eva: Add backlight support
  pwm_backlight: Add deferred probe support
  ARM: mach-shmobile: Kota2: Use leds-pwm + rmob-tpu-pwm
  leds: Remove leds-renesas-tpu driver

FWIW, having tested the first version of this series on an Armadillo board
I have no objections to v2 of this series.
