[PATCH V8 0/7] remoteproc: imx_rproc: support i.MX8QM/QXP

[Peng Fan (OSS)]

From: Peng Fan <peng.fan@xxxxxxx>

V8:
 patch 2/7: Per Krzysztof, keep alphabetical order for compatible string
 Patch 6/7: Add comments to explain the tx_ch/rx_ch check in imx_rproc_xtr_mbox_init,
            to address comment: https://lore.kernel.org/all/20221017173335.GA121862@p14s/

V7:
 patch 3/7: use dev_err, and R-b from Mathieu
 patch 4/7: Add comment when "num_pd <= 1", add R-b from Mathieu
 patch 5/7: Typo has->have, add R-b from Mathieu
 patch 6/7: add detach hook to free the mbox. As wrote in the patch commit log,
          imx_rproc_xtr_mbox_init is called both in probe and attach hook to resolve
          mbox defer probe, so there is check in imx_rproc_xtr_mbox_init.
	    Moved imx_rproc_free_mbox out from parition notify to detach hook
 patch 7/7: since detach hook moved to patch 6/7, so only enable recovery feature.

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.
