Subject: [PATCH v2 1/1] arm64: dts: NS2 secondary core enablement via PSCI
Date: Wed, 20 Apr 2016 13:40:02 -0400 [thread overview]
Message-ID: <1461174002-18178-1-git-send-email-luke.starrett@broadcom.com> (raw)
Declare PSCI-1.0 node and enable CPU_ON method via PSCI. Spin-table
memreserve has been removed as well as syscon based reset, as PSCI-1.0
expects reset implementation in firmware.
