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".
