If smi.h include this file, it also is ok. then these two files(mtk_iommu.h and mtk_smi.c) don't need include this. the MTK_LARB_NR_MAX only is used in mtk_iommu.h and mtk_smi.c directly, thus I use that two files include this file currently. locally I think it may be helpful for readable. is this ok? > > Regards, > Matthias > > > + > > +#define MTK_M4U_ID(larb, port) (((larb) << 5) | (port)) > > +#define MTK_M4U_TO_LARB(id)(((id) >> 5) & 0xf) > > +#define MTK_M4U_TO_PORT(id)((id) & 0x1f) > > + > > +#endif > > > > ___ > Linux-mediatek mailing list > linux-media...@lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-mediatek ___ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
