Based upon Marek Vasut work in l4f00242t03.c, this driver provides basic init and power on/off functionality for this device through the sysfs lcd interface. Unfortunately Datasheet for this device are not available and all the control sequences sent to the display were copied from the freescale driver that in the i.MX31 Linux BSP. As in the i.MX31PDK board the core and io suppliers are voltage regulators, that functionality is embedded here, but not strict.

The LCD uses SPI for initialization and powerdown sequences. No further defails are specified in the datasheet about the initialization/powerdown sequence, just the magic numbers that have to be sent over SPI bus. This LCD can be found in the Aeronix Zipit Z2 handheld.

Expose this functionality via the backlight API. Since when used in this configuration the current sink and boost convertor are very tightly coupled with a multi-stage startup for the current sink which overlaps with the boost convertor startup this driver bypasses the regulator API.
