Hans de Goede 421c98d7d2 sunxi: display: Use PWM to drive backlight where applicable ... When the backlight's pwm input is connected to a pwm output of the SoC, actually use pwm to drive the backlight. The mean reason for doing this is to fix the backlight turning off for aprox. 1 second while the kernel is booting. This is caused by the kernel actually using pwm to drive the backlight, so that it can dim the backlight. First the pwm driver loads and switches the pinmux for the pin driving the backlight's pwm input to the pwm controller. Then about 1s later the actual backlight driver loads and tells the pwm driver to actually update the pwm settings, which have a power-on-reset value of "off". An additional advantage is that this allows us to initatiate the backlight at 80%, which is the kernel default, avoiding a brightness change while the kernel loads.
