   4 Subject: [PATCH] dtoverlays: Add inverted override property to
   5  ssd1306-spi
   6
   7 The new ssd130x DRM driver supports both SSD1306 I2C and SPI panels and is
   8 compatible with the ssd1307fb driver bindings. So the "solomon,com-invdir"
   9 DT property (to invert the COM pin scan dir) can also be used for SPI now.
  10
  11 This allows to configure panels whose scan direction needs to be inverted.
