Subject: [PATCH V5 5/8] remoteproc: imx_rproc: initial support for mutilple start/stop method
Date: Wed, 21 Apr 2021 10:20:19 +0800
Message-ID: <1618971622-30539-6-git-send-email-peng.fan@oss.nxp.com> (raw)
In-Reply-To: <1618971622-30539-1-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.
