[RFC v3 0/7] MT8173 DRM support

[Philipp Zabel]

Hi,

this is an update to the MT8173 DRM support RFC. 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").

I have changed the device tree bindings to group the display function blocks
under a display-subsystem node. I'm not happy with this organisation as the
display-subsystem node is not really a physical bus. I'd much prefer connecting
the function blocks with an of-graph, if it is acceptable for just the graph
to cost >8 KiB dtb size.

The added HDMI driver still directly accesses an undocumented register in the
apmixedsys (clock-controller) register space to set a divider of the TVDPLL.
That will be fixed as soon as I understand what this clock is connected to.

Changes since v2:
 - Grouped DISP function block nodes under the display-subsystem node
 - Added of-graph ports to binding documentation
 - Dropped legacy framebuffer support
 - Dropped plane zpos property
 - Update plane->disp_size in atomic_update instead of atomic_check
 - Added asynchronous commit support
 - Split DSI and MIPI TX (MIPI D-PHY) drivers
 - Added DPI driver
 - Added HDMI driver
 - Added HDMI DDC I2C master driver
 - Added HDMI PHY driver
