SSD2825 is an innovative and cost-effective MIPI Bridge Chip solution targeting high resolution smartphones. It can convert 24bit RGB interface into 4-lane MIPI-DSI interface to drive extremely high resolution display modules of up to 800 x 1366, while supporting AMOLED, a-si LCD or LTPS advanced panel technologies for smartphone applications.
Bridge is wrapped in panel uClass model for wider compatibility.

Please can you use dm_spi_xfer() instead, thoughout?
I will replace it, but isn't spi_xfer preferable over dm_spi_xfer? I remember that I had doubts about which to use.
Also note that when you add a printf() for errors, the string is stored and it increases code size. It might be better to use log_debug(), unless the errors are likely.
