Subject: [PATCH v2 00/36] drm/vc4: Add support for BCM2712 / Pi5 display
hardware
This series adds the required DRM, clock, and DT changes
required to support the display hardware on Pi5.
There are a couple of minor fixes first before the main patches.
Many of the patches were authored by Maxime whilst working
for us, however there have been a number of fixes squashed
into his original patches as issues have been found. I also
reworked the way UBM allocations are done to avoid double
buffering of the handles as they are quite a limited resource.
There are 2 variants of the IP. Most Pi5's released to date
have used the C1 step of the SoC, whilst the 2GB Pi5 released
in August is using the D0 step, as will other boards in future.
Due to various reasons the register map got reworked between
the steps, so there is extra code to handle the differences.
Which step is in use is read out of the hardware, so they
share a compatible string.
Thanks!

Changes in v2:
- Collected Acks and R-b tags
- Dropped patch 1 "drm/vc4: Limit max_bpc to 8 on Pi0-3". Already fixed as
noted by Maxime.
- Fix unintialised var "mux" in vc6_hvs_pv_muxing_commit.
- Fixed uninitialised var "reg" in vc4_hvs_cob_init.
- Make bcm2712_mop_data and bcm2712_moplet_data static.
- Removed the "disable_turbo" line from the struct in
raspberrypi_clock_property
- I'm confused by the CI error "performing pointer arithmetic on a null
pointer has undefined behavior" for PCI_IOBASE as I'm not using it.
- Link to v1: https://lore.kernel.org/r/20241023-drm-vc4-2712-support-v1-0-1cc2d5594907@raspberrypi.com
