Uwe Kleine-König	b7783c6258	pwm: raspberrypi-poe: Simplify using devm_pwmchip_add() ... This allows to drop the platform_driver's remove function.

Nicolas Saenz Julienne	79caa362ea	pwm: Add Raspberry Pi Firmware based PWM bus ... Adds support to control the PWM bus available in official Raspberry Pi PoE HAT. Only RPi's co-processor has access to it, so commands have to be sent through RPi's firmware mailbox interface.
