[PATCH v3 00/11] arm64: dts: describe the Lynx 10G and 28G SerDes blocks for Layerscape SoCs

[PATCH v3 00/11] arm64: dts: describe the Lynx 10G and 28G SerDes blocks for Layerscape SoCs

[Ioana Ciornei]

This patch set adds the device tree nodes for the Lynx10G SerDes blocks
found on the LS1028A, LS1046A, LS1088A and LS2088A SoCs.

The first 5 patches slowly change the LX2160A DTS support to a new
structure which does not use any delete-node or delete-property
directives. This is a direct result of the discussion with Frank in the
v2 of this set:
https://lore.kernel.org/all/akwAmzAbtg0Ejey0@SMW015318/

Patches 5 and 6 transition the LX2160A and LX2162 SoC dtsi to use the
device-specific Lynx28G SerDes compatible while the remainder of the set
adds the SerDes block descriptions for the LS1028A, LS1046A, LS2088A and
LS1088A SoCs.

Changes in v3:
- Changes how the LX216XA based SoC dtsi files are structured.
- Split the enabling of serdes_1 into a separate patch
- Split the LX2162A changes to another patch
- Move the status property to be the last for serdes_3
- Move the changes to the new fsl-lx2160a-serdes.dtsi file

Changes in v2:
- Enable serdes_1 on all board DTs that has consumers for it.
- Use the proper name for serdes_3 in fsl-lx2162a.dtsi.
- Remove paragraph from commit message which mentioned some consumer
changes that are no longer needed nor part of the commit.
- Change the size of the SerDes region to 0x2000

[PATCH v3 01/11] arm64: dts: lx2160a: explicitly enable serdes_1 node

[Ioana Ciornei]

Explicitly enable the serdes_1 node in all board DT files. This is
needed in order to be able to change the default status of the node to
"disabled" from the SoC DT file.

[PATCH v3 02/11] arm64: dts: lx2160a: extract the PCIe nodes into a separate dtsi

[Ioana Ciornei]

One of the major differences between LX2160A Rev1 and Rev2 is the PCIe
controller used. With the final goal of removing any usage of
delete-node or delete-property from the current LX2160A related dts
files, move the PCIe nodes found on the LX2160A Rev1 into a separate
dtsi file. This will make it easier to include the appropriate dtsi
file describing the PCIe controller depending on the SoC revision in a
follow-up patch.

No actual change in the DT nodes found in the final DTBs is intended.

[PATCH v3 03/11] arm64: dts: lx2160a: extract the SerDes nodes into a separate dtsi

[Ioana Ciornei]

In terms of its SerDes blocks, the LX2162A is not properly described
since it just inherits the LX2160A SerDes nodes, which is not correct.
In order to fix this but also avoid the usage of delete-node, we need to
first extract the SerDes nodes currently found in fsl-lx2160a.dtsi into a
separate dtsi.

This patch does not intend to do any actual changes in the final dtb
files, only a dt node move.

[PATCH v3 04/11] arm64: dts: lx2160a: extract the PCIe from LX2160A Rev2 into a separate file

[Ioana Ciornei]

The LX2160A Rev2 SoC changed the PCIe controllers used. This difference
is reflected in the fsl-lx2160a-rev2.dtsi file which modifies the
relevant dt nodes so that they match the actual HW.

Extract these modifications into a separate dtsi file as a first step
into a complete overhaul of the LX216xA related dts files with the
intent to not use delete-node or delete-property. No final dtb changes
are expected with this patch.

[PATCH v3 05/11] arm64: dts: lx2160a: split the dtsi to avoid delete-property

[Ioana Ciornei]

This patch reorganizes the LX216XA related dts/dtsi files with the
intent to avoid any delete-property usage.

Taken into consideration the differences between the LX2160A Rev1,
LX2160A Rev2 and LX2162A SoCs, the following structure is created:

fsl-lx216x.dtsi		---> fsl-lx2160a-rev1.dtsi (PCIe gen4, 3 SerDes blocks)
(no PCIe, no SerDes)	---> fsl-lx2160a-rev2.dtsi (PCIe gen3, 3 SerDes blocks)
			---> fsl-lx2162a.dtsi (PCIe gen3, 2 SerDes blocks)

Each PCIe integration or SerDes block instantiation has its own dtsi
file which gets to be included only by the necessary SoC level dtsi
file.

The dtsi file describing the PCIe controllers found on LX2160A Rev2 is
also changed so that it does not work on a already defined node but
rather it describes it entirely.

In order to decouple the LX2162A from LX2160A, a new dtsi
fsl-lx2162a-serdes.dtsi file is added which, for the moment, only
duplicates the SerDes related nodes found already for LX2160A.

Any dts which previously included fsl-lx2160a.dtsi now includes the
-rev1 version and any dts which is clearly intended for LX2162A based
board now includes the fsl-lx2162a.dtsi. This patch does not intent any
changes into the final dtbs.

Changes in v3:
- New patch
- The only changes in the final dtbs are phandle related ones.

[PATCH v3 06/11] arm64: dts: lx2160a: transition to device-specific SerDes compatible strings

[Ioana Ciornei]

Align to the modern fsl,lynx-28g.yaml binding, where the SoC and SerDes
instance is present in the compatible string, to allow reliable per-lane
capability detection and per-lane customization of electrical properties.

The modern bindings are backward-incompatible with old kernels, due
to the consumer phandles being either in one form or in another, as
explained here:
https://lore.kernel.org/lkml/20250930140735.mvo3jii7wgmzh2bs@skbuf/

Also mark the serdes_1 node as disabled by default since any dts using
it enables it explicitly now.

Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com>
---
Changes in v3:
- Split the enabling of serdes_1 into a separate patch
- Split the LX2162A changes to another patch
- Move the status property to be the last for serdes_3
- Move the changes to the new fsl-lx2160a-serdes.dtsi file

Changes in v2:
- Enable serdes_1 on all board DTs that has consumers for it.
- Use the proper name for serdes_3 in fsl-lx2162a.dtsi.
- Remove paragraph from commit message which mentioned some consumer
changes that are no longer needed nor part of the commit.

[Ioana Ciornei]

Align to the modern fsl,lynx-28g.yaml binding for the LX2162A SoC, where
the SoC and SerDes instance is present in the compatible string, to
allow reliable per-lane capability detection and per-lane customization
of electrical properties.

Since one of the major differences between LX2162A and LX2160A is the
SerDes, add the necessary nodes to its own fsl-lx2162a-serdes.dtsi file.

Also mark the serdes_1 node as disabled by default since any dts using
it enables it explicitly now.

[PATCH v3 11/11] arm64: dts: ls1088a: describe the Lynx 10G SerDes blocks

[Ioana Ciornei]

Describe the two Lynx 10G SerDes blocks and their associated lanes found
on the LS1088A SoC. The nodes are left disabled at the SoC level; board
DTs will enable them once there are consumers.

Note that the SerDes block #2 is non-networking, meaning that it will
not get probed by the Lynx10G SerDes PHY driver and it's only added for
a complete hardware description.

Changes in v3:
- None

Changes in v2:
- Change the size of the region to 0x2000

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [High] Incomplete device tree update: the patch claims to explicitly enable the `serdes_1` node in "all board DT files" to prepare for an SoC default change, but misses several LX2160A and LX2162A board files.

arm64: dts: lx2160a: explicitly enable serdes_1 node

This commit enables the serdes_1 node in board-specific device tree files.
This change prepares for a subsequent update that will set the default
status of the serdes_1 node to disabled in the main SoC device tree.

> Explicitly enable the serdes_1 node in all board DT files. This is
> needed in order to be able to change the default status of the node to
> "disabled" from the SoC DT file.

[Severity: High]
Does this commit miss updating several other lx2160a and lx2162a board
files?

If the default status in the SoC device tree file is changed to disabled,
it appears boards that rely on serdes_1 for high-speed IO (PCIe,
networking, SATA) might be left without functional interfaces.

Could the following board files also need the serdes_1 node enabled:
- arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dts
- arch/arm64/boot/dts/freescale/fsl-lx2160a-qds.dts
- arch/arm64/boot/dts/freescale/fsl-lx2162a-qds.dts
- arch/arm64/boot/dts/freescale/fsl-lx2160a-tqmlx2160a.dtsi

Is there a reason these files were omitted from this patch?

This is not a valid concern.

The above listed board files were not updated because they are not
active users of the serdes_1 node (no MAC node is currently referencing
it), thus enabling it is not necessary.

Overall look good, let wait for some days for other reviewers.
