Browse source 
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.
