I would like you to provide more information. The original code works
in mt8173, why do you modify this? The description may be something
like this:
According to data sheet, the width is in bits [31, 16] and height is
in bits [15, 0]. Even though wrong setting may works in some SoC such
as mt8173, but it does not work in mt8192.
Regards,
Chun-Kuang.

it still works in mt8192.
just modify this follow data sheet

This patch is not strongly related to MT8192, so move this patch out
of this series.
