The driver code has to be adapted to implement the above changes, and the compatible string 'mediatek,mt8196-mmc' is added to driver and devicetree bindings. --- Changes in v2: - Use compatible string 'mediatek,mt8196-mmc' to replace 'mediatek,msdc-v2'; - Remove the 'mediatek,stop-dly-sel', 'mediatek,pop-en-cnt' and 'mediatek, prohibit-gate-cg' in devicetree bindings, due to SoC dependent; - Add 'stop_dly_sel' and 'pop_en_cnt' to the compatiblity structure for different register settings; - The SoC's upgraded version would discard the bus design that detect source clock CG when the CPU access the IP registers, so drop the related control flow with 'prohibit_gate_cg' flag.
