Pull pwm fix from Uwe Kleine-König:
 "Fix period setting in imx-tpm driver and a maintainer update

  Erik Schumacher found and fixed a problem in the calculation of the
  PWM period setting yielding too long periods. Trevor Gamblin - who
  already cared about mainlining the pwm-axi-pwmgen driver - stepped
  forward as an additional reviewer.

  Thanks to Erik and Trevor"
