* struct drm_panel_funcs - perform operations on a given panel
*
* The .prepare() function is typically called before the display controller
* starts to transmit video data. Panel drivers can use this to turn the panel
* on and wait for it to become ready. If additional configuration is required
* (via a control bus such as I2C, SPI or DSI for example) this is a good time
* to do that.
*
* After the display controller has started transmitting video data, it's safe
* to call the .enable() function. This will typically enable the backlight to
* make the image on screen visible. Some panels require a certain amount of
* time or frames before the image is displayed. This function is responsible
* for taking this into account before enabling the backlight to avoid visual
* glitches.
*
* Before stopping video transmission from the display controller it can be
* necessary to turn off the panel to avoid visual glitches. This is done in
* the .disable() function. Analogously to .enable() this typically involves
* turning off the backlight and waiting for some time to m
