Subject: [PATCH V6 0/7] remoteproc: imx_rproc: support i.MX8QM/QXP

From: Peng Fan <peng.fan@....com>

V6:
 Two changes are made:
1. 
 In V5, patch 3 has a wrong logic in imx_rproc_put_scu, see [1], however
 patch 4 fixed the wrong logic, as below:

-	if (!imx_sc_rm_is_resource_owned(priv->ipc_handle, priv->rsrc_id))
-		return;
+	if (imx_sc_rm_is_resource_owned(priv->ipc_handle, priv->rsrc_id))
+		return imx_rproc_detach_pd(rproc);

 In V6, patch 3 fixed the wrong logic, drop the fix in patch 4. And patch 4
 changed as below, because put scu not has return value.
                imx_rproc_detach_pd(rproc);
                return;

2. Include patch 7/7 to enable attach recovery, because the attach recovery
 feature has been supported in remoteproc core.

V5:
 The patchset could not apply on latest remoteproc for-next branch,
 so rebased. Only patch 6 has a minor conflict, other patches are not
 changed.

 Drop 'reg' property Per remoteproc maintainer
 Drop mcore self recovery, until we land in common framework support.
