hi all:

Now we are porting a lcd panel with HX8394F controller IC on imx8mq platform, and mipi cmds sending seems complete, but no frame show on panel. After check with vendor, they replied that HX8394F supports only mipi dcs cmd, and it's little endian.

We already change panel driver to use mipi dcs write buffer cmd, but it still has no frame appear. Can you provide how to set little endian at mipi driver, then it can send out the mipi cmd correctly?

also, any debugging  suggestion is welcome.
