[PATCH v3 0/5] Renesas TPU PWM support

[Laurent Pinchart]

This is the third version of the Renesas TPU PWM unit support patches. The
patch series deprecates and removes the leds-renesas-tpu driver in favor of a
combination of leds-pwm and pwm-renesas-tpu. As an added bonus patch 4/5
removes function GPIOs support from the sh73a0 platform. mach-shmobile is now
free of function GPIOs. We still need volunteer(s) to migrate arch/sh.

I believe I've addressed most comments received in response to v2, with the
exception of channel allocation at .request() time for which I haven't received
any answer to my questions. That will hopefully not be a showstopper.

I've tested the code on Armadillo only as I don't have access to a kota2
board. This is why I've added backlight support to Armadillo as part of this
set.

The patches are based on Simon's renesas-next-20130611v2 tag. I've pushed them
to

        git://linuxtv.org/pinchartl/fbdev.git pinmux/3.10/tpu

Given the risk of conflicts on arch/arm/mach-shmobile it would probably be
easier to merge the set through Simon's tree. Thierry, would you be fine with
that ?

Changes since v2:

- Dropped SH Mobile arch patches that have already been merged
- Replaced active_low pdata field with pwm_polarity
- Replaced TPU_PWM_ID with pwm_lookup's
- Set the platform_driver .owner field
- Replaced devm_ioremap_nocache() with devm_ioremap_resource()
- Added a .set_polarity() implementation
- Use kernel block comment style
- Don't enable/disable the clock around clk_get_rate()
- Removed duplicate sanity checks in the .config() operation

Changes since v1:

- Renamed the pwm-rmob driver to pwm-renesas-tpu, as TPU units are found in
  Renesas SH-Mobile, R-Mobile and R-Car SoCs.
- Added TPU clock and pin groups for r8a7790.
