Subject: [PATCH v8 9/9] arm64: dts: qcom: Enable Q6v5 WCSS for ipq8074 SoC
Date: Sat, 30 Jan 2021 10:50:13 +0530	[thread overview]
Message-ID: <1611984013-10201-10-git-send-email-gokulsri@codeaurora.org> (raw)
In-Reply-To: <1611984013-10201-1-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.
