- Subject: [PATCH] arm64: dts: broadcom: bcmbca: bcm4908: set
- brcm,wp-not-connected
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Every described BCM4908 board has WP pin not connected. This caused
- problems for drivers since day 0 but there was no property to describe
- that properly. Projects like OpenWrt were modifying Linux driver to deal
- with it.
- It's not clear if that is hardware limitation or just reference design
- being copied over and over but this applies to all known / supported
- BCM4908 boards. Handle it by marking WP as not connected by default.
- Fixes: 2961f69f151c ("arm64: dts: broadcom: add BCM4908 and Asus GT-AC5300 early DTS files")
