Amlogic Meson8/8b/8m2 have a built-in HDMI PHY in the HHI register
region. Unfortunately only few register bits are documented. For
HHI_HDMI_PHY_CNTL0 the magic numbers are taken from the 3.10 vendor
kernel.

The registers which are managed by the meson-gxl-usb3 PHY driver are
actually "USB control" registers (which are "glue" registers which
manage OTG detection and routing of the OTG capable port between the
DWC2 peripheral-only controller and the DWC3 host-only controller).

Drop the meson-gxl-usb3 PHY driver now that the dwc3-meson-g12a-usb
driver supports the USB control registers on GXL and GXM SoCs (these
were previously managed by the meson-gxl-usb3 PHY driver).

This adds support for the PCI PHY found in the Amlogic AXG SoC Family.
This will allow to mutualize code in pci-meson.c between AXG and G12A
SoC.

This PHY also uses and chains an analog PHY, which on AXG platform
is needed to have reliable PCIe communication.

This adds support for the MIPI analog PHY which is also used for PCIE
found in the Amlogic AXG SoC Family.

MIPI or PCIE selection is done by the #phy-cells, making the mode
static and exclusive.

For now only PCIE functionality is supported.

This PHY will be used to replace the mipi_enable clock gating logic
which was mistakenly added in the clock subsystem. This also activates
a non documented band gap bit in those registers that allows reliable
PCIE clock signal generation on AXG platforms.

It supports Host and/or Peripheral mode, depending on it's position.
The first PHY is only used as Host, but the second supports Dual modes
defined by the USB Control Glue HW in front of the USB Controllers.

<title>phy: amlogic: add USB3 PHY support for Meson GXL and GXM</title>

<id>urn:sha1:115de9fd682ccdc6b7c3142287339dbada7a7807</id>
<content type='text'>
This adds a new driver for the USB3 PHY found on Meson GXL and GXM SoCs
(both SoCs are using the same USB PHY register layout).

Unfortunately there is no documentation for this PHY in the public S905X
datasheet (published for example by Khadas). What we know so far about
this PHY:
- even though the Meson GXL and GXM SoCs do not expose an USB3 port (the
  dwc3 controller only has USB2 ports enabled) we need to initialize the
  USB3 PHY (specifically USB_R1_U3H_FLADJ_30MHZ_REG_MASK). Without this
  initialization high-speed USB devices (especially USB hard disks and
  thumb drives, slower devices like mice do not seem to be affected)
- on some boards the USB3 PHY starts in "device mode" - we want to bring
  it into a known state (by switching it to host mode for now).
- it is responsible for the OTG detection and for switching the first
  USB2 PHY between host and peripheral (aka device) mode. an interrupt
  can be used to detect changes between host and device mode.

There are five inputs to this register area:
- the clock and reset line for the USB3 PHY itself
- the clock and reset line for the peripheral mode and OTG detection
  logic (on the GXL and GXM SoCs these are the same clock and reset line
  as for the USB3 PHY itself, but Amlogic sees this as two different
  components - even though they share the same register space - so they
  have to be passed individually to allow specifying different inputs on
  other SoCs if needed)
- the interrupt for the OTG detection logic

The whole OTG detection logic is not implemented yet.
