The series of patches are used to support xHCI host controller on MediaTek SoCs which has a glue layer IPPC (IP Port Control), and add USB function on T-PHY including T-PHY V1 and V2; Finally add USB related nodes for MT7629 platform.
The files of xhci-mtk.* and phy-mtk-tphy.* are ported from Linux Kenrel 5.6-rc1
v3 changes: 1. provide non/inline edev_get_child_count() suggested by Simon 2. squash [PATCH v2 02/10] into [PATCH v2 03/10] suggested by Simon 3. use macros to access IPPC registers suggested by Marek
v2 changes: 1. move ofnode_get_child_count() into ofnode.c suggested by Simon 2. add a test item for ofnode_get_child_count() suggested by Simon 3. use clk_bulk to get clocks suggested by Marek 4. use clrsetbits_le32() etc suggeseted by Marek 5. get the count of phys by dev_get_child_count() 6. drop reference to fixed clock clk20m
