[PATCH v3 0/5] Patches to add support for Rockchip dwc2 controller

[Kever Yang]

These patches to add support for dwc2 controller found in
Rockchip processors rk3066, rk3188 and rk3288,
and enable dts for rk3288 evb.

Changes in v3:
- Moved out of pin control and sort by base address
- EHCI and HSIC move new for version 3.
- Rebase

Changes in v2:
- Split out dr_mode and rk3288 bindings.
- add compatible "snps,dwc2" bingding info
- set most parameters as driver auto-detect
- change the node name from 'dwc2' to 'usb'
- evb patch added in version 2
