The A13 Q8 tablet, following the A13 reference tablet design, has the system's fixed 3.3V rail feed the VCC supply of the LCD panel. Additional voltage rails used by the panel are generated using a regulator fed from the unregulated IPSOUT output of the PMIC. The latter is unrepresentable in the device tree. Both are controlled with MOSFETs by the enable GPIO added in the previous patch. The actual enable or reset pin for the panel is tied directly to LCD-VCC after the MOSFET.
