Thanks very much for the applying. I'd like to show there is a little
conflict with a smi change[1] in /include/soc/mediatek/smi.h.
This is the detailed conflict:
--- a/include/soc/mediatek/smi.h
+++ b/include/soc/mediatek/smi.h
@@ -9,7 +9,7 @@
#include <linux/bitops.h>
#include <linux/device.h>
-#ifdef CONFIG_MTK_SMI
+#if IS_ENABLED(CONFIG_MTK_SMI) <---The smi patch change here.
#define MTK_LARB_NR_MAX 16 <---This iommu patchset delete this line.
This code is simple. Please feel free to tell me how to do this if this
is not convenient to merge.
