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

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

[Laurent Pinchart]

Hi everybody,

Here are four patches that implement backlight support for the Armadillo 800
EVA board. 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.

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

I have tested the above 4 patches, they look good.

This also looks good, but I do not have access
to a Kota2 board to test these changes.

I would be happy to test them if I I had the hardware.

Otherwise, I suggest a review from Magnus.

This also looks good but it probably wants to
be reviewed by Magnus.

That's why I've CC'ed him. Magnus, it looks like you're the only one to have 
access to a Kota2 board. Sorry for giving you more work :-)
