Hi,
this is an update to the May RFC to add MT8173 DRM support. These patches have a build dependency on two other patches on top of v4.3-rc1: https://patchwork.kernel.org/patch/6914941 ("iommu: Implement common IOMMU ops for DMA mapping"), and https://patchwork.kernel.org/patch/6928621 ("memory: mediatek: Add SMI driver").
The device tree bindings are changed to describe the actual hardware blocks, a display-subsystem node ties them together. This driver currently supports a single output stream (OVL0 -> COLOR0 -> AAL -> OD -> RDMA0 -> UFOE -> DSI0) to a MIPI DSI device.
best regards Philipp Zabel
