/*
|
||
|
|
* Device Tree overlay to connect a JDI LT070ME05000 DSI panel to DSI1.
|
||
|
|
* This uses 4 DSI data lanes, so can only be used with a Compute Module.
|
||
|
|
*
|
||
|
|
* The overlay is for V2 of Harlab's interface board that uses a PCA9536 to
|
||
|
|
* handle the panel's control GPIOs instead of wiring it back to Pi GPIOs.
|
||
|
|
*
|
||
|
|
* Credit to Andrey Vostrukhin of Harlab for the overlay.
|
||
|
|
*
|
||
|
|
* Refer to https://github.com/harlab/CM4_LCD_LT070ME05000 for schematics and
|
||
|
|
* other documentation.
