From: ChiYuan Huang <cy_huang@xxxxxxxxxxx> Add a devicetree binding documentation for the MT6360 Type-C driver. usb typec: mt6360: Rename DT binding doument from mt6360 to mt636x Change binding document file name from mt6360 to mt636xfor the future compatible. Also change internal description from mt6360 to mt636x.
