If anyone has any objections, please let me know. ------------------ From: Alibek Omarov [ Upstream commit dafebd0f9a4f56b10d7fbda0bff1f540d16a2ea4 ] PLL rate on RK356x is calculated through the simple formula: ((24000000 / _refdiv) * _fbdiv) / (_postdiv1 * _postdiv2) The PLL rate setting for 78.75MHz seems to be copied from 96MHz so this patch fixes it and configures it properly.
