[PATCH v3 00/11] arm64: dts: describe the Lynx 10G and 28G SerDes blocks for Layerscape SoCs
From: Ioana Ciornei
Date: Fri Jul 17 2026 - 08:07:55 EST
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
