Cc: linux-arm-kernel, devicetree, linux-kernel
The following series of patches add support for the following
on J721S2 common processor board,
- USB
- SerDes
- OSPI
- PCIe
Changes from v11:
* Cleaned up comments for disabled nodes
* Removed deprecated properties for flash node
Changes from v10:
* Removed the ti,j721e-system-controller bindings document
patch introduced in v9
* Updated mux-controller node with "reg" property to fix dtbs
warnings
* For the nodes which are disabled by default, added comments to
provide the reason behind it
* Dropped Link tags in all patches
Changes from v9:
* Disabled nodes in main.dtsi and enable them in the board
specific DT file
Changes from v8:
* Update the ti,j721e-system-controller bindings document
* Fix dtbs warnings
Changes from v7:
* Fix node names as per bindings document
Changes from v6:
* Changes to ti,j721s2-wiz-10g compatible string from ti,am64-wiz-10g but
requires this series to be merged first
Ref: https://lore.kernel.org/linux-arm-kernel/20221122092203.762308-1-mranostay@ti.com/
* Removed unused pcie1_ep based on feedback
* Switch from incorrect "ti,j721e-system-controller", "syscon", "simple-mfd" compatible for
SPI node to "simple-bus"
Changes from v5:
* Removed Cc from commit messages to reduce clutter
* Squashed changes for device tree nodes that get modified latter in the patchset
series
Changes from v4:
* Add my Signed-off-by lines to all patchsets
Changes from v3:
* Rebased changes on top of '[PATCH 00/12] TI J7x Disable Incomplete DT Nodes'
* Removed "dt-bindings: PCI: Add host mode device-id for j721s2 platform" patch and
send it own series to avoid a dependency that would hold up other patches in this
series.
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.
Changes from v1:
* Resolve issues with dt schema reporting
* Minor changes related to consistency on node naming and value

Changes from v11:
* Cleaned up comments
Changes from v10:
* Fixed dtbs warnings by adding "reg" property to the mux-controller nodes
* Documented the reason for disabling the nodes by default
* Removed Link tag from commit message
Changes from v9:
* Disabled serdes related nodes by default in common DT file
Changes from v8:
* No change
Changes from v7:
* Updated mux-controller node name
Changes from v6:
* Fixed the incorrect "compatible" property
Changes from v5:
* Removed Cc tag from commit message
Changes from v4:
* No change
Changes from v3:
* No change
Changes from v2:
* 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.
Changes from v1:
* Update mux-controller node name

* [PATCH v12 5/8] arm64: dts: ti: k3-j721s2-common-proc-board: Add USB support

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 up to 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.

Since this node doesn't need pinmux, why is it default disabled? Same for
the other parent nodes in this series.

In this patch and others in this series, since child node is disabled,
I thought of disabling the parent as well. And to later enable the
parent node at the time when the child node needs to be enabled.

Could you please provide your input on this?
If the preferred way is to keep the parent node enabled, then I will
do so. For the IPs added in this series, if the parent node needs additional
information such as pinmux, gpio, I will disable both parent and child.
And if only child node(s) need additional info, then I will keep the parent
enabled and children disabled.

Could you please provide your input on this?
If the preferred way is to keep the parent node enabled, then I will
do so. For the IPs added in this series, if the parent node needs additional
information such as pinmux, gpio, I will disable both parent and child.
And if only child node(s) need additional info, then I will keep the parent
enabled and children disabled.
