Subject: [PATCH v1 0/5] arm64: meson: support Amlogic A1 USB OTG controller

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)
