[PATCH v2 0/2] MediaTek MT8195 HDMI PHY Fixes
Posted by AngeloGioacchino Del Regno 2 weeks ago
Changes in v2:
 - Fixed commit description of patch [2/2] (Mani)

This series adds two fixes for the MT8195-class HDMI PHY, found in
MT8195, MT8188 and Genio variants.

This is fixing PLL calculation, and TMDS clock dividers, to achieve
all of the modes requiring data rates higher than 3.4Gbps, with the
successfully tested target being 3840x2160@60Hz.

This was tested on MT8395 MediaTek Genio 1200, Radxa NIO-12L and on
MT8390 MediaTek Genio 700, with 3 different HDMI displays (two TVs
and a 4k LG workstation display).
