However, experiments show that the mux is not present in A64, so the compatible string of dual-PLL-input HDMI PHY clock must be changed to use R40 in it rather than A64. This patchset does this change. Because the compatible string is introduced in 4.19, this patchset should be applied to 4.19 during RC stage, otherwise this error will exist forever for DT compatibility.
