Subject: [PATCH] dt-bindings: arm: Allow 32-bit 'cpu-release-addr' values
Date: Thu, 3 Mar 2022 10:57:09 -0600 [thread overview]
Message-ID: <20220303165710.1859862-1-robh@kernel.org> (raw)
While the DT Spec says 'cpu-release-addr' is always 64-bit, some 32-bit Arm
DTs used a 32-bit value. We're now stuck with those cases, so add uint32 as
a valid type.

+ The DT specification defines this as 64-bit always, but some 32-bit Arm
+ systems have used a 32-bit value which must be supported.
Required for systems that have an "enable-method"
property value of "spin-table".
- On ARM v8 64-bit systems must be a two cell
- property identifying a 64-bit zero-initialised
- memory location.
