for HiFive Unleashed board. The patches are mostly based on
Wesley's patch.

Wesley W. Terpstra (4):
  pwm: sifive: Add DT documentation for SiFive PWM Controller.
  pwm: sifive: Add a driver for SiFive SoC PWM
  gpio: sifive: Add DT documentation for SiFive GPIO.
  gpio: sifive: Add GPIO driver for SiFive SoCs
