In the .board_init() callback will set up a mux register in the Nomadik system controller. It so happens that the platform has two display output engines, and we have to poke a bit in a special register to make sure the right engine is muxed in as they are mutually exclusive. The Nomadik CLCD variant is instantiated on a platform where it is combined with a 800x480 TPO WVGA display. In the .panel_init() hook we will detect this display from the compatible string and set it up. We also add .enable() and .disable() callbacks for it as the sleep state is software controlled. The display is connected with a special 3-wire serial bus (this is sadly neither I2C or SPI) using three GPIO lines that we bitbang to detect the display and enable/disable sleep state.
