drivers/staging/greybus/pwm.c uses the old style PWM callbacks, new drivers
should stick to the atomic API instead.

 * Convert all uses of the old GPIO API from <linux/gpio.h> to the
   GPIO descriptor API in <linux/gpio/consumer.h> and look up GPIO
   lines from device tree or ACPI.
+* Make pwm.c use the struct pwm_ops::apply instead of ::config, ::set_polarity,
+  ::enable and ::disable.
