Subject: [PATCH 2/2 v3] ARM: dts: bcm53016: Add devicetree for D-Link DWL-8610AP
Date: Wed, 19 Oct 2022 21:34:49 +0200 [thread overview]
Message-ID: <20221019193449.3036010-2-linus.walleij@linaro.org> (raw)
In-Reply-To: <20221019193449.3036010-1-linus.walleij@linaro.org>
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".
Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
---
ChangeLog v2->v3:
- Drop extra words in device description, the make and model is
enough.
- Rename the second (backup) firmware partition to "firmware2"
so as not to confuse OpenWrt scripts.
- Resend with the binding patch.
ChangeLog v1->v2:
- Relicense as dual GPL+MIT
- Parse TRX partitions in the NAND flash instead of just fixed
partitions, use fixed partitions to chunk up the main
parts of the flash then add trx compatibles to those
nodes that have TRX headers.
- Use 5 bit ECC like the device does.
