From: Rob Herring Date: Thu, 3 Mar 2022 16:57:09 +0000 (-0600) Subject: dt-bindings: arm: Allow 32-bit 'cpu-release-addr' values X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ea87f1eb4fd81375a3abf564f6f2999561985831;p=linux.git dt-bindings: arm: Allow 32-bit 'cpu-release-addr' values 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.
