The 5" and 7" Raspberry Pi 720x1280 Display 2 MCU is a bit more
complex than the original Display 1 ATTINY88 and the binding is
also a bit more demanding. Split the binding into separate file
and fill in required gpio-controller, #gpio-cells and #pwm-cells
which must be present for the V2 MCU. Include mention of the 5"
panel in the description of Display 2, as the 5" panel uses the
same MCU.

The RaspberryPi 5" and 7" display 2 has an MCU-based regulator, PWM
|
|
backlight and GPIO controller on the PCB, which is used to turn the
|
|
display unit on/off and control the backlight.
