Hi,
this MT8173 DRM update changes the clock bindings once more, as the MIPI_TX D-PHY and the HDMI PHY have internal PLLs that are better abstracted using the common clock framework. The clock outputs of the PHY modules are routed to the respective encoders, in the HDMI case by way of the TOP clock module. I'd like it if Michael or Stephen could take a look at the clock patches and maybe give an Ack or a Nope for this to be merged through the DRM tree.
Various other issues have been fixed, for more details see the individual patches.
Some changes since v7: - Added PLL reference input clocks and output clocks to the MIPI TX D-PHY and HDMI PHY nodes - Added HS input clocks to the MIPI DSI encoder nodes - Dropped the hdmitx_dig_cts clock from the TOP dividers, it is not a child of tvdpll_445p5m anyway. This clock signal really is provided by the HDMI PHY - Added "power-domains" properties to all nodes in the MM domain - Documented the merge and split function block bindings - Merged Daniel's wait for exclusive fences on incoming framebuffers using reservation_object_wait_timeout_rcu in .atomic_complete() into the DRM driver patch. This allowed to drop the drm/atomic-helper wait_for_fences export patch again. - Added missing atomic destroy_state callbacks, cleaned up reset callbacks - Added a pending_planes flag to mtk_crtc so we can atomically update the plane configuration - Fixed OD ddp_comp function setup - Separated enabling MIPI TX phy output from enabling the PLL (via CCF), this allows to keep the pixel clock running separately from the encoder output when disabling the crtc, to wait for the last vblank. - Fixed mtk_dpi_power_on reference counting - Fill ELD info in the HDMI driver, for future audio support. - Renamed the MT8173 specific HDMI PHY driver, as MT2701 has a different PHY. - Update iommus binding to v7 IOMMU patches.
The following patches are needed to cleanly apply the device tree changes on top of v4.4-rc1:
