Subject: [PATCH v7 9/9] arm64: dts: qcom: Enable Q6v5 WCSS for ipq8074 SoC
Date: Thu, 30 Jul 2020 17:56:43 +0530
Message-ID: <1596112003-31663-10-git-send-email-gokulsri@codeaurora.org> (raw)
In-Reply-To: <1596112003-31663-1-git-send-email-gokulsri@codeaurora.org>

Enable remoteproc WCSS PIL driver with glink
and ssr subdevices. Also configures shared memory
and enables smp2p and mailboxes required for IPC.
