Subject: [PATCH] arm64: dts: broadcom: bcmbca: bcm4908: set
|

brcm,wp-not-connected

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.
|
||
|
