Change in v6:
1)use devm_clk_get function for required clocks
Change in v5:
1)remove Reviewed-by tag
2)use devm_clk_bulk_get_optional instead of devm_clk_get_optional
for bulk clks
Change in v4:
1)drop "vmmc" and "vqmmc" desciption in mtk-sd.yaml
2)add vmmq/vqmmc supplies and the pinctrls to required properties
3)change dbg level and exit this function
4)use devm_clk_get_optional instead of devm_clk_get function
5)remove else branch for sys_clk_cg
Change in v3:
1)change maintainers name in mtk-sd.yaml
2)change "compatible" properties to enum type and sort it
3)drop these properties: "reg" and "interrupts"
4)add "maxItems" constraints on these properties: "vmmc-supply", "vqmmc-supply",
"assigned-clocks", "assigned-clock-parents"
5)add "minimum" and "maximum" constraints on these properties: "mediatek,hs400-cmd-int-delay",
"mediatek,latch-ck", "hs400-ds-delay", "mediatek,hs200-cmd-int-delay"
Change in v2:
Convert mtk-sd to json-schema
Wenbin Mei (4):
dt-bindings: mmc: Convert mtk-sd to json-schema
mmc: dt-bindings: add support for MT8192 SoC
arm64: dts: mt8192: add mmc device node
mmc: mediatek: Add subsys clock control for MT8192 msdc
