Subject: [PATCH 00/16] move at91 and avr32 to the PWM framework, remove obsolete drivers

Hi,

This patch set swtiches the at91 and avr32 SoCs and board to the generic PWM
framework. This allows to remove the obsolete leds-atmel-pwm, atmel-pwm-bl and
atmel_pwm drivers.

The first 6 patches take care of the AT91 boards and removes a useless function
in the process.

Patch 7 makes pwm-ateml buildable for AVR32

Patch 8 allows setting the pwm polarity for pwm_bl when using platform data.
This is required afterwards for the favr-32

Patches 9-13 take care of the AVR32 boards. This has only been compile tested as
I don't own any of those boards.

And the last 3 patches are removing the now obsolete drivers.

As a note, the atmel_pwm driver has two features not yet available through
pwm-atmel:
 - it is possible to pass an IRQ handler that will get called each time one of
   the channel period has been acheived.
 - it was possible to set clka and clkb, two clock that divided mck before
   feeding the pwm controller.

Those features are not used by anything in the mainline. I'm not sure we can
implement the first one. We'll get back the second one once all the boards have
swtiched to the common clock framework.
