- From 9f66e1dd82e3186aee95282657512ca2aef1afe0 Mon Sep 17 00:00:00 2001
- From: Linus Walleij <[email protected]>
- Date: Wed, 19 Oct 2022 21:34:49 +0200
- Subject: [PATCH] ARM: dts: bcm53016: Add devicetree for D-Link DWL-8610AP
- This adds a device tree for the BCM53016-based D-Link DWL-8610AP
- access point wireless router.
- The TRX-format partitions had to be named "firmware" due to
- an OpenWrt patch that only accepts parting such nodes if they
- are named "firmware".
