Subject: [PATCH V6 5/8] remoteproc: imx_rproc: initial support for mutilple start/stop method
Date: Thu, 6 May 2021 12:08:40 +0800 [thread overview]
Message-ID: <1620274123-1461-6-git-send-email-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <1620274123-1461-1-git-send-email-peng.fan@oss.nxp.com>
From: Peng Fan <peng.fan@nxp.com>
Add three methods IMX_RPROC_NONE(no need start/stop), IMX_RPROC_MMIO
(start/stop through mmio) and IMX_RPROC_SMC(start/stop through ARM SMCCC).
The current SoCs supported are all using IMX_RPROC_MMIO.
