Subject: [PATCH] dtoverlays: Add inverted override property to
|
||
|
|
ssd1306-spi
|
||
|
|
|
||
|
|
The new ssd130x DRM driver supports both SSD1306 I2C and SPI panels and is
|
||
|
|
compatible with the ssd1307fb driver bindings. So the "solomon,com-invdir"
|
||
|
|
DT property (to invert the COM pin scan dir) can also be used for SPI now.
|
||
|
|
|
||
|
|
This allows to configure panels whose scan direction needs to be inverted.
|
||
|
