From: Fabien Parent <fparent@xxxxxxxxxxxx> Until now the port ID was always encoded as a 5-bit data. On MT8365, the port ID is encoded as a 6-bit data. This requires to add extra macro F_MMU_INT_ID_LARB_ID_EXT, and F_MMU_INT_ID_PORT_ID_EXT in order to support 6-bit encoded port IDs.

Same here. After fixing that: Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@xxxxxxxxxxxxx>
