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 output has
been tested too). There's a couple of rough edges still that should be
addressed in the next versions:
  - After a modeset, it's likely that the pixels will be shifted by one.
  - Dual output doesn't work
  - The transposer (and thus writeback) doesn't work either and conflicts
    with the output mux too.

Let me know if you have any comments
Maxime

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

The firmware running on the RPi VideoCore can be used to discover and
change the various clocks running in the BCM2711. Since devices will
need to use them through the DT, let's add a pretty simple binding.

The BCM2711 has a unit controlling the HDMI0 and HDMI1 clock and reset
signals. Let's add a binding for it.

The HDMI block has a block that controls clocks and reset signals to the
HDMI0 and HDMI1 controllers.

Let's expose that through a clock driver implementing a clock and reset
provider.

The BCM283x SoCs have a display pipeline composed of several controllers
with device tree bindings that are supported by Linux.

Now that we have the DT validation in place, let's split into separate
files and convert the device tree bindings for those controllers to
schemas.

This is just a 1:1 conversion though, and some bindings were incomplete so
it results in example validation warnings that are going to be addressed in
the following patches.

While the device tree and the driver expected a clock-names property, it
wasn't explicitly documented in the previous binding. Make sure it is now.

The BCM2711 comes with a new VideoCore. Add a compatible for it.

The BCM2711 comes with other pixelvalves that have different requirements
and capabilities. Let's document their compatible.

The HDMI controllers found in the BCM2711 SoC need some adjustments to the
bindings, especially since the registers have been shuffled around in more
register ranges.

Hi Maxime,

Thanks for your V2 patch series!  I'm testing it.

This patch series is applied upon mainline kernel 5.7-rc2 cleanly and built.
System can boot into console text mode, but no graphic UI.

Get the error in vc5_hdmi_phy_init(), and full dmesg is at [1]:

Yes, the HDMI cable is connected to HDMI0 port on RPi 4.

According to the log, I think it is 1920x1080:
Apr 27 15:37:25 endless gdm-Xorg-:0[1960]: (II) modeset(0): Output
HDMI-1 connected
Apr 27 15:37:25 endless gdm-Xorg-:0[1960]: (II) modeset(0): Output
HDMI-2 disconnected
Apr 27 15:37:25 endless gdm-Xorg-:0[1960]: (II) modeset(0): Output
Composite-1 disconnected
Apr 27 15:37:25 endless gdm-Xorg-:0[1960]: (II) modeset(0): Using
exact sizes for initial modes
Apr 27 15:37:25 endless gdm-Xorg-:0[1960]: (II) modeset(0): Output
HDMI-1 using initial mode 1920x1080 +0+0

It looks to be fairly standard then, and I'm testing on the same resolution so
it should be alright.

Given from your log, it looks like you're running as arm64 though, while I stuck
with arm32, so it could be the explanation.

Can you share your config.txt and .config so that I can try to reproduce it
here?

Thanks!
Maxime

Here is the only one line in config.txt:
enable_uart=1

Actually, we make the Raspberry Pi's firmware bring up U-Boot, then
U-Boot boots kernel.

Not really any reason to make this a child node. The parent can be a

This was meant to provide some consistency for that driver. It already has a nod
for the GPIOs exposed through the firmware in the RPi where you could make the
exact same argument, so I guess that, while we shouldn't make the same choices
if we had to design it from scratch, it's more important to keep the same design
choices for a given binding?

If we were to create a new binding, sure, but we're merely reusing the old
binding that is already there. The only reason it's in a separate file is
because you said it would be clearer in a separate file.

I gave it a try with U-Boot with my latest work and couldn't reproduce it, so it
seems that I fixed it along the way

Is your latest work available in a git branch anywhere that we could
test directly?

I'm about to send a v3 today or tomorrow, I can Cc you (and Jian-Hong) if you
want.

That would be great, although given the potentially inconsistent
results we've been seeing so far it would be great if you could
additionally push a git branch somewhere.
That way we can have higher confidence that we are applying exactly
the same patches to the same base etc.

Thanks

So I sent a new iteration yesterday, and of course forgot to cc you... Sorry for
that.

I've pushed my current branch here:
https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git/log/?h=rpi4-kms

Thanks to Maxime!

I have tried your repository on branch rpi4-kms.  The DRM VC4 is used!
But got some issues:
1. Some weird error message in dmesg.  Not sure it is related, or not
[    5.219321] [drm:vc5_hdmi_init_resources] *ERROR* Failed to get
HDMI state machine clock
https://gist.github.com/starnight/3f317dca121065a361cf08e91225e389

2. The screen flashes suddenly sometimes.

3. The higher resolutions, like 1920x1080 ... are lost after hot
re-plug HDMI cable (HDMI0)

That's a deferred probing. The first time the HDMI driver is being
probed, the firmware clock driver has not been probed yet. It's making
another attempt later on, which succeeds.

I'm not sure on how to exactly reproduce those issues (or what they are)
though, can you expand on this?

I append drm.debug=0x3 to boot command.  Whenever, the screen flashes,
I notice the logs like this:

I should explain this in more detail.  Here are the steps to reproduce
this issue:
1. Before unplug the HDMI cable from HDMI0 port.

Sorry for getting back at it so late. I just tested with modetest only
and my current branch and it seems to behave properly. Did you had to
run X to get that issue, or is it just how you noticed it?

Also, was that with the branch based on 5.7 I pushed on my git tree on
kernel.org or some earlier revision of the series?

Thanks!
Maxime

Thanks for coming back :)

I use GNOME 3.36 with Xorg 1.20.4.

To understand when it starts to hit the issues, I separate to step by step:
1. System boots into command line mode first (systemd multi-user.target)
2. Execute Xorg, then xterm.
3. Execute mutter upon the screen of Xorg.

I tried both branches rpi4-kms and rpi4-kms-5.7 of
https://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git
Both of the branches hit issues:
* The screen flashes suddenly sometimes.  This happens after mutter is launched.
* The higher resolutions, like 1920x1080 ... are lost after hot
re-plug HDMI cable (HDMI0).  HDMI cable connects to HDMI0 -> HDMI1 ->
HDMI0.  This happens not only with GNOME, but also pure Xorg.
