[PATCH v7 07/13] arm64: dts: qcom: sdm845: Use QMP property to control load state

From: Sibi Sankar
Date: Thu Sep 16 2021 - 10:02:01 EST


Use the Qualcomm Mailbox Protocol (QMP) property to control the load
state resources on SDM845 SoCs and drop deprecated power-domains exposed
by AOSS QMP node.
