23 - Power:
24 - Vdd: Power supply for display module
25 Called power-supply in this binding.
26 - Vddi: Logic level supply for interface signals
27 Called io-supply in this binding.
28 - Interface:
29 - CSx: Chip select
30 - SCL: Serial clock
31 - Dout: Serial out
32 - Din: Serial in
33 - SDA: Bidrectional in/out
34 - D/CX: Data/command selection, high=data, low=command
35 Called dc-gpios in this binding.
36 - RESX: Reset when low
37 Called reset-gpios in this binding.
41 - Option 1: 9-bit mode and D/CX as the 9th bit
45 - Option 2: 16-bit mode and D/CX as a 9th bit
49 - Option 3: 8-bit mode and D/CX as a separate interface line
53 The panel resolution is specified using the panel-timing node properties
54 hactive (width) and vactive (height). The other mandatory panel-timing
55 properties should be set to zero except clock-frequency which can be
59 hback-porch (x-offset) and vback-porch (y-offset).
