The patches have been tested on i.MX6, i.MX53 and with the ti-ehrpwm.c driver. Changes wrt. v2: - make the use of '#pwm-cells = <3>' optional, so that the change does not break existing DT blobs as suggested by Arnd Bergmann and Sascha Hauer. Changes wrt. v3: - implemented the approach suggested by Sascha Hauer - don't modify struct pwm_ops in the imx_pwm probe function
