This patch series introduces full support for the Amlogic A1 USB controller
in OTG mode (peripheral and host modes switching).
Previously, Amlogic's patch series [1] was applied to the upstream tree,
but it only had USB host mode support.
Furthermore, the device tree patchset [2] wasn't merged due to a missing
clk driver.
Patchset [2] has been completely reworked:
- changed register base offsets to proper values
- introduced dwc2 in peripheral mode
- OTG mode support
- the SoB of Amlogic authors still remain
Testing:
- USB OTG role switching between gadget and host - OK
- Peripheral mode - OK (tested with adb shell/push/pop)
- Host mode - OK (tested only USB enumeration and detection)
