Merge tag 'at91-drivers' of git://github.com/at91linux/linux-at91 into next/drivers

Merge "at91: drivers for 3.17 #1" from Nicolas Ferre:

"This update delayed to 3.17, is about replacing the existing calls to the
older, non-standard drivers by the use of the newer "pwm-atmel" which takes
advantage of the PWM framework.
All concerned maintainer gave their acknowledgement to the relevant patches.
At the end, it removes three obsolete drivers and the diffstat looks pretty
nice as well."

Atmel PWM driver update for 3.17
- move to the new PWM driver which uses PWM framework
- remove 3 obsolete drivers (atmel-pwm-bl.c, leds-atmel-pwm.c and atmel_pwm.c)

* tag 'at91-drivers' of git://github.com/at91linux/linux-at91:
  misc: atmel_pwm: remove obsolete driver
  leds: atmel-pwm: remove obsolete driver
  backlight: atmel-pwm-bl: remove obsolete driver
  avr32: update defconfig to use the generic PWM framework
  avr32: favr-32: use generic pwm_bl driver
  avr32: merisc: use generic leds_pwm driver
  avr32: MRMT: use generic leds_pwm driver
  avr32/at32ap: switch to the generic PWM framework
  PWM: atmel: allow building for AVR32
  ARM: at91: remove useless at91_pwm_leds()
  ARM: at91: at91sam9rl: switch to generic PWM framework
  ARM: at91: sam9263ek: use generic leds_pwm driver
  ARM: at91: at91sam9263: switch to generic PWM framework
  ARM: at91: sam9m10g45ek: use generic leds_pwm driver
  ARM: at91: at91sam9g45: switch to generic PWM framework

-/**
- * struct pwm_channel - driver handle to a PWM channel
- * @regs: base of this channel's registers
- * @index: number of this channel (0..31)
- * @mck: base clock rate, which can be prescaled and maybe subdivided
- *
- * Drivers initialize a pwm_channel structure using pwm_channel_alloc().
- * Then they configure its clock rate (derived from MCK), alignment,
- * polarity, and duty cycle by writing directly to the channel registers,
- * before enabling the channel by calling pwm_channel_enable().
- *
- * After emitting a PWM signal for the desired length of time, drivers
- * may then pwm_channel_disable() or pwm_channel_free().  Both of these
- * disable the channel, but when it's freed the IRQ is deconfigured and
- * the channel must later be re-allocated and reconfigured.
- *
- * Note that if the period or duty cycle need to be changed while the
- * PWM channel is operating, drivers must use the PWM_CUPD double buffer
- * mechanism, either polling until they change or getting implicitly
- * notified through a once-per-period interrupt handler.
