	)

mipi_dsi_dcs_write() - send DCS write command

Parameters

dsi	DSI peripheral device
cmd	DCS command
data	buffer containing the command payload
len	command payload length

This function will automatically choose the right data type depending on the command payload length.

Returns

The number of bytes successfully transmitted or a negative error code on failure.
