The BCM2711 has another clock that needs to be ramped up depending on the pixel rate: the pixel BVB clock. Add the code to adjust that clock when changing the mode.

In order to avoid pixels getting stuck in an unflushable FIFO, we need when we disable the HDMI controller to switch away from getting our pixels from the pixelvalve and instead use blank pixels, and switch back to the pixelvalve when we enable the HDMI controller.

In order to prevent some pixels getting stuck in an unflushable FIFO on bcm2711, we need to enable the HVS, the pixelvalve (the CRTC) and the HDMI controller (the encoder) in an intertwined way, and with tight delays. However, the atomic callbacks don't really provide a way to work with either constraints, so we need to roll our own callbacks so that we can provide those guarantees. Since those callbacks have been implemented and called in the CRTC code, we can just implement them in the HDMI driver now.

The register range used for audio setup in the previous generations of SoC were always the second range in the device tree.

The HSM clock needs to be running at 101% the pixel clock of the HDMI controller, however it's shared between the two HDMI controllers, which means that if the resolutions are different between the two HDMI controllers, and the lowest resolution is on the second (in enable order) controller, the first HDMI controller will end up with a smaller than expected clock rate. Since we don't really need an exact frequency there, we can simply change the minimum rate we expect instead.

The HSM clock needs to be setup at around 101% of the pixel rate. This was done previously by setting the clock rate to 163.7MHz at probe time and only check in mode_valid whether the mode pixel clock was under the pixel clock +1% or not. However, with 4k we need to change that frequency to a higher frequency than 163.7MHz, and yet want to have the lowest clock as possible to have a decent power saving. Let's change that logic a bit by setting the clock rate of the HSM clock to the pixel rate at encoder_enable time. This would work for the BCM2711 that support 4k resolutions and has a clock that can provide it, but we still have to take care of a 4k panel plugged on a BCM283x SoCs that wouldn't be able to use those modes, so let's define the limit in the variant.

Whenever the code needs to access the vc4_hdmi structure from a DRM connector or encoder, it first accesses the drm_device associated to the connector, then retrieve the drm_dev private data which gives it a pointer to our vc4_dev, and will finally follow the vc4_hdmi pointer in that structure. That will also give us some trouble when having multiple controllers, but now that we have our encoder and connector structures that are part of vc4_hdmi, we can simply call container_of on the DRM connector or encoder and retrieve the vc4_hdmi structure directly.

Now that we are passing the vc4_hdmi structure to the connector init function, we can simply use the pointer in that structure instead of having the pointer as an argument.

the vc4_hdmi driver has some custom structures to hold the data it needs to associate with the drm_encoder and drm_connector structures. However, it allocates them separately from the vc4_hdmi structure which makes it more complicated than it needs to be. Move those structures to be contained by vc4_hdmi and update the code accordingly.

We will need to share the vc4_hdmi and related structures with multiple files, so let's create a header for it.

We're calling vc4_debugfs_add_file with our struct vc4_hdmi pointer set in the private field, but we don't use that field and go through the main struct vc4_dev to get it. Let's use the private field directly, that will save us some trouble later on.
