Subject: [PATCH v2 1/4] dt-bindings: power: reset: Convert mode-.* properties to array
Date: Sun, 14 Apr 2024 12:30:24 -0700	[thread overview]
Message-ID: <20240414-arm-psci-system_reset2-vendor-reboots-v2-1-da9a055a648f@quicinc.com> (raw)
In-Reply-To: <20240414-arm-psci-system_reset2-vendor-reboots-v2-0-da9a055a648f@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.
