Hi everyone,
Here's a (pretty long) series to introduce support in the VC4 DRM driver for the display pipeline found in the BCM2711 (and thus the RaspberryPi 4).
The main differences are that there's two HDMI controllers and that there's more pixelvalve now. Those pixelvalve come with a mux in the HVS that still have only 3 FIFOs. Both of those differences are breaking a bunch of expectations in the driver, so we first need a good bunch of cleanup and reworks to introduce support for the new controllers.
Similarly, the HDMI controller has all its registers shuffled and split in multiple controllers now, so we need a bunch of changes to support this as well.
Only the HDMI support is enabled for now (even though the DPI and DSI outputs have been tested too).
Let me know if you have any comments Maxime

Changes from v3: - Rebased on top of next-20200708 - Added a name to the HDMI audio codec component - Only disable the BCM2711 HDMI pixelvalves at boot - Fixed an error in the HVS binding - Fix a framebuffer size condition that was inverted - Changed the channel allocation algorithm using Eric's suggestion - Always write the muxing values instead of updating if needed - Improved a bit the hvs_available_channels comment in the structure - Change atomic_complete_commit code to use for_each_new_crtc_in_state - Change the muxing code to take into account disparities between the BCM2711 and previous SoCs. - Only change the clock rate on BCM2711 during a modeset - Fix a crash at atomic_disable - Use clk_set_min_rate for the core clock too - Add a few defines, and simplify the FIFO level stuff - Reordered the patches according to Eric's reviews - Fixed a regression with VID_CTL setting on RPI3
Changes from v2: - Rebased on top of next-20200526 - Split the firmware clock series away - Removed the stuck pixel (with all the subsequent pixels being shifted by one - Fixed the writeback issue too. - Fix the dual output - Fixed the return value of phy_get_cp_current - Enhanced the comment on the reset delay - Increase the max width and height - Made a proper Kconfig option for the DVP clock driver - Fixed the alsa card name collision
Changes from v1: - Rebased on top of 5.7-rc1 - Run checkpatch - Added audio support - Fixed some HDMI timeouts - Swiched to clk_hw_register_gate_parent_data - Reorder Kconfig symbols in drivers/i2c/busses - Make the firmware clocks a child of the firmware node - Switch DVP clock driver to clk_hw interface - constify raspberrypi_clk_data in raspberrypi_clock_property - Don't mark firmware clocks as IGNORE_UNUSED - Change from reset_ms to reset_us in reset-simple, and add a bit more comments - Remove generic clk patch to test if a NULL pointer is returned - Removed misleading message in the is_prepared renaming patch commit message - Constify HDMI controller variants - Fix a bug in the allocation size of the clk data array - Added a mention in the DT binding conversion patches about the breakage - Merged a few fixes from kbuild - Fixed a few bisection and CEC build issues - Collected Acked-by and Reviewed-by - Change Dave email address to raspberrypi.com
