+Commit 973d1607d936 ("clk: mediatek: mt2701: use mtk_clk_simple_probe to
+simplify driver") broke DT bindings as the highest index was reduced by
+1 because the id count starts from 1 and not from 0.
+
+Fix this, like for other drivers which had the same issue, by adding a
+dummy clk at index 0.

+Some of the audio subsystem clocks defined in clk-mt2701.h aren't
+actually used by the driver. This broke conversion to
+mtk_clk_simple_probe which expects that the highest possible clk id is
+defined by the ARRAY_SIZE.
+
+Add additional dummy clocks to fill the gaps and remain compatible with
+the existing DT bindings.

+Touching DISP_REG_OVL_PITCH_MSB leads to video overlay on MT2701, MT7623N
+and probably other older SoCs being broken.
+
+Only touching it on hardware which actually supports AFBC like it was
+before commit c410fa9b07c3 ("drm/mediatek: Add AFBC support to Mediatek
+DRM driver") fixes it.
