> Hello,
> this patch series add support for sending MIPI DSI command packets to the Renesas RZ/G2L MIPI DSI
> driver.
> 
> Tested on a custom board with a SolidRun RZ/G2L SOM, with two different LCD panels using the jd9365da
> and st7703 drivers.
> 
> Tested short and long writes.
> 
> Tested read of 1 byte, 2 bytes and long reads. Note that to test long reads, most LCD panels need to
> be sent a DCS configuration command to increase the maximum packet size, which is set to 1 byte by
> default (at least on the two panels that I tested).
