Subject: [RFC 3/3] arm64: dts: qcom: sa8775p-ride: Enable support for firmware managed resources
Date: Tue, 5 Mar 2024 22:27:38 +0530 [thread overview]
Message-ID: <1709657858-8563-4-git-send-email-quic_sriramd@quicinc.com> (raw)
In-Reply-To: <1709657858-8563-1-git-send-email-quic_sriramd@quicinc.com>
Establish the channel and domain mapping for the power domains to connect
with firmware, enabling the firmware to handle the assigned resources.
Since these delegated resources will remain invisible to the operating
system, ensure that any references to them are removed.
