[PATCH v3 0/9] J721S2: Add support for additional IPs

[PATCH v3 0/9] J721S2: Add support for additional IPs

[Matt Ranostay]

The following series of patches add support for the following
on J721S2 common processor board,

- USB
- SerDes
- OSPI
- PCIe

Changes from v1:
* Resolve issues with dt schema reporting
* Minor changes related to consistency on node naming and value

Changes from v2:
* Added PCIe RC + EP enablement patchsets
* Added device-id for j722s2 PCIe host in dt documentation
* Reworked SERDES + WIZ enablement patchset to use properies for clocks
  defines versus entire devicetree nodes. Results in cleaner code that
  doesn't break dt-schema or the driver functionality.

[PATCH v3 5/9] arm64: dts: ti: k3-j721s2-common-proc-board: Add USB support

[Matt Ranostay]

From: Aswath Govindraju <a-govindraju@ti.com>

The board uses lane 1 of SERDES for USB. Set the mux
accordingly.

The USB controller and EVM supports super-speed for USB0
on the Type-C port. However, the SERDES has a limitation
that upto 2 protocols can be used at a time. The SERDES is
wired for PCIe, eDP and USB super-speed. It has been
chosen to use PCIe and eDP as default. So restrict
USB0 to high-speed mode.

It gets hard when we mix driver bindings with dts patches. Please do not
do that - in this case, the binding would be better go through  Lorenzo
Pieralisi <lorenzo.pieralisi@arm.com> (who needs to be in the To list)
and the corresponding list linux-pci@vger.kernel.org in CC

This allows driver bindings to be independently merged of the dts
changes - also allows dts maintainers to pick patches after ensuring
bindings (and any corresponding driver changes) are merged into master
(which locks things down). please disconnect the series such that the
dts can alone be picked up without dtbs_check problems.

That said, i'd rather we rebase this after Andrew's cleanup series in
[1] and follow the same pattern for new nodes being added.
