[PATCH v2 2/3] ARM: dts: orion5x: Add D-Link DNS-323 Device Tree

Mauri Sandberg maukka at ext.kapsi.fi
Thu Sep 22 13:24:57 PDT 2022


Add a device tree for D-Link DNS-323. The device has three different
variants; A1, B1 and C1. Common parts are included in a .dtsi file
and each hardware variant has its own .dts file.

Signed-off-by: Mauri Sandberg <maukka at ext.kapsi.fi>
---
changes from v1
 - split patches, this one adds the device tree
 - set pciec and pcie1 nodes to 'okay'
