If anyone has any objections, please let me know. ------------------ From: Esteban Urrutia [ Upstream commit d149c8b2c0146a01f1be326ddb1e182b55aee638 ] Add the compatible for the MDSS client on the Snapdragon 8 Gen 1 so it can be properly configured by the IOMMU driver. Otherwise, there is an unhandled context fault, because the framebuffer is already configured in UEFI.
