This series aims to add a led-backlight driver, similar to pwm-backlight, but using a LED class device underneath. LED framework has no support for DT or getting a LED class driver from another kernel driver, so I added minimal functionality to led-class to get led-backlight working. Changes to v2: - power supply is now optional - cosmetic changes - no-op function for led_put() when !CONFIG_LEDS_CLASS Changes to v1: - Split LED OF parts into separate .h and .c files - Check for CONFIG_OF and CONFIG_LEDS_CLASS where relevant to leave unused code out. - Improved error prints and comments a bit - Added put_device() into led_put(), as the device was gotten from class_find_device() which requires a put_device() call.
