* XXX: MIPI_DATA_ADDRESS, MIPI_DATA_LENGTH, MIPI_COMMAND_LENGTH, and
* MIPI_COMMAND_ADDRESS registers.
*
* Apparently these registers provide a MIPI adapter level way to send (lots of)
* commands and data to the receiver, without having to write the commands and
* data to MIPI_{HS,LP}_GEN_{CTRL,DATA} registers word by word.
*
* Presumably for anything other than MIPI_DCS_WRITE_MEMORY_START and
* MIPI_DCS_WRITE_MEMORY_CONTINUE (which are used to update the external
* framebuffer in command mode displays) these are just an optimization that can
* come later.
*
* For memory writes, these should probably be used for performance.
