Subject: [PATCH v3 1/4] dt-bindings: power: reset: Convert mode-.* properties to array
Date: Wed, 15 May 2024 16:09:44 -0700 [thread overview]
Message-ID: <20240515-arm-psci-system_reset2-vendor-reboots-v3-1-16dd4f9c0ab4@quicinc.com> (raw)
In-Reply-To: <20240515-arm-psci-system_reset2-vendor-reboots-v3-0-16dd4f9c0ab4@quicinc.com>
PSCI reboot mode will map a mode name to multiple magic values instead
of just one. Convert the mode-.* property to an array. Users of the
reboot-mode schema will need to specify the maxItems of the mode-.*
properties. Existing users will all be 1.
