Subject: [PATCH v2 3/3] drm/panfrost: add Amlogic GPU integration quirks
Date: Wed, 16 Sep 2020 17:01:47 +0200 [thread overview]
Message-ID: <20200916150147.25753-4-narmstrong@baylibre.com> (raw)
In-Reply-To: <20200916150147.25753-1-narmstrong@baylibre.com>
This adds the required GPU quirks, including the quirk in the PWR registers at the GPU
reset time and the IOMMU quirk for shareability issues observed on G52 in Amlogic G12B SoCs.
