[PATCH v5 0/4] 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 v5:
- max_transfer_size change to 65535 to met the requirement of
  header file
- change the sort order of dwc2 in rk3288.dtsi
- don't enable otg port for evb

Changes in v4:
- max_transfer_size change to 65536, this should be enough
  for most transfer, the hardware auto-detect will set this
  to 0x7ffff which may make dma_alloc_coherent fail when
  non-dword aligned buf from driver like usbnet happen.
- remove EHCI and HSIC dts patch for Doug had post it seprately.

Changes in v3:
- 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
- evb patch added in version 2

IMHO this series is ready to go in for 3.18 whenever maintainers feel
it's the right time.

IMHO this series is ready to go in for 3.18.  I'm assuming Heiko will
pick it up once the bindings have landed.  It already has my tags.  ;)
