Subject: [PATCH v4 3/3] iommu/mediatek: add support for MT8167
Date: Mon, 7 Sep 2020 12:16:49 +0200 [thread overview]
Message-ID: <20200907101649.1573134-3-fparent@baylibre.com> (raw)
In-Reply-To: <20200907101649.1573134-1-fparent@baylibre.com>
Add support for the IOMMU on MT8167
Signed-off-by: Fabien Parent <fparent@baylibre.com>
---
V4;
* Removed HAS_4GB_MODE flag since this SoC does not seem to support it
V3:
* use LEGACY_IVRP_PADDR flag instead of using a platform data member
V2:
* removed if based on m4u_plat, and using instead the new
has_legacy_ivrp_paddr member that was introduced in patch 2.
