Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.
Note that for armada I also went ahead and made the ioctl array const.
Only cc'ing the driver people who've not been converted (everyone else
is way too much).

The burst length is configured in VIU_OSD1_FIFO_CTRL_STAT[31] and
VIU_OSD1_FIFO_CTRL_STAT[11:10]. The public S905D3 datasheet describes
this as:
- 0x0 = up to 24 per burst
- 0x1 = up to 32 per burst
- 0x2 = up to 48 per burst
- 0x3 = up to 64 per burst
- 0x4 = up to 96 per burst
- 0x5 = up to 128 per burst
The lower two bits map to VIU_OSD1_FIFO_CTRL_STAT[11:10] while the upper
bit maps to VIU_OSD1_FIFO_CTRL_STAT[31].
Replace meson_viu_osd_burst_length_reg() with pre-defined macros which
set these values. meson_viu_osd_burst_length_reg() always returned 0
(for the two used values: 32 and 64 at least) and thus incorrectly set
the burst size to 24.

This patch adds support for the YUV420 output from the Amlogic Meson SoCs
Video Processing Unit to the HDMI Controller.
The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YUV444 pixel stream to a YUV420
stream.
In addition if pixel stream down-sampling, the Y Cb Cr components must
also be mapped differently to align with the HDMI2.0 specifications.
This mode needs a different clock generation scheme since the TMDS PHY
clock must match the 10x ratio with the YUV420 pixel clock, but
the video encoder must run at 2x the pixel clock.
This patch enables the bridge bus format negociation, and handles
the YUV420 case if selected by the negociation.

Change it to use consistent naming and avoid NULL.

This adds all the OSD configuration plumbing to support the AFBC decoders
path to display of the OSD1 plane.
The Amlogic GXM and G12A AFBC decoders are integrated very differently.
The Amlogic GXM has a direct output path to the OSD1 VIU pixel input,
because the GXM AFBC decoder seem to be a custom IP developed by Amlogic.
On the other side, the Amlogic G12A AFBC decoder seems to be an external
IP that emit pixels on an AXI master hooked to a "Mali Unpack" block
feeding the OSD1 VIU pixel input.
This uses a weird "0x1000000" internal HW physical address on both
sides to transfer the pixels.
For Amlogic GXM, the supported pixel formats are the same as the normal
linear OSD1 mode.
On the other side, Amlogic added support for all AFBC v1.2 formats for
the G12A AFBC integration.
For simplicity, we stick to the already supported formats for now.

This adds the driver for the ARM Framebuffer Compression decoders found
in the Amlogic GXM and G12A SoCs.
The Amlogic GXM and G12A AFBC decoder are totally different, the GXM only
handling only the AFBC v1.0 modes and the G12A decoder handling the
AFBC v1.2 modes.
The G12A AFBC decoder is an external IP integrated in the video pipeline,
and the GXM AFBC decoder seems to the an Amlogic custom decoder more
tighly integrated in the video pipeline.
The GXM AFBC decoder can handle only one AFBC plane for 2 available
OSD planes available in HW, and the G12A AFBC decoder can handle up
to 4 AFBC planes for up to 3 OSD planes available in HW.
The Amlogic GXM supports 16x16 SPARSE and 16x16 SPLIT AFBC buffers up
to 4k.
On the other side, for G12A SPLIT is mandatory in 16x16 block mode, but
for 4k modes 32x8+SPLIT AFBC buffers is manadatory for performances reasons.
The RDMA is used here to reset and program the AFBC decoder unit
on each vsync without involving the interrupt handler that can
be masked for a long period of time, producing display glitches.
For this we use the meson_rdma_writel_sync() which adds the register
write tuple (VPU register offset and register value) to the RDMA buffer
and write the value to the HW.
When enabled, the RDMA is enabled to rewrite the same sequence at the
next VSYNC event, until a new buffer is committed to the OSD plane.
Then the Amlogic G12A is switched to RDMA, the Amlogic GXM Decoder
doesn't need a reset/reprogram at each vsync, but needs to keep the
vsync interrupt enabled to trigger the RDMA module.

With commit 222ec1618c ("drm: Add aspect ratio parsing in DRM
layer") the drm core started honoring the picture_aspect_ratio field
when comparing two drm_display_modes. Prior to that it was ignored.
When the CVBS encoder driver was initially submitted there was no aspect
ratio check.
Switch from drm_mode_equal() to drm_mode_match() without
DRM_MODE_MATCH_ASPECT_RATIO to fix "kmscube" and X.org output using the
CVBS connector. When (for example) kmscube sets the output mode when
using the CVBS connector it passes HDMI_PICTURE_ASPECT_NONE, making the
drm_mode_equal() fail as it include the aspect ratio.
Prior to this patch kmscube reported:
failed to set mode: Invalid argument
The CVBS mode checking in the sun4i (drivers/gpu/drm/sun4i/sun4i_tv.c
sun4i_tv_mode_to_drm_mode) and ZTE (drivers/gpu/drm/zte/zx_tvenc.c
tvenc_mode_{pal,ntsc}) drivers don't set the "picture_aspect_ratio" at
all. The Meson VPU driver does not rely on the aspect ratio for the CVBS
output so we can safely decouple it from the hdmi_picture_aspect
setting.

This patch introduce new enum which contains all VPU family (GXBB,
GXL, GXM and G12A).
This enum is used to detect the VPU compatible with the device.
We only need to set .data to the corresponding enum in the device
table, no need to check .compatible string anymore.

So far, the drm_format_plane_height/width functions were operating on the
format's fourcc and was doing a lookup to retrieve the drm_format_info
structure and return the cpp.
However, this is inefficient since in most cases, we will have the
drm_format_info pointer already available so we shouldn't have to perform a
new lookup. Some drm_fourcc functions also already operate on the
drm_format_info pointer for that reason, so the API is quite inconsistent
there.
Let's follow the latter pattern and remove the extra lookup while being a
bit more consistent.
In order to be extra consistent, also rename that function to
drm_format_info_plane_cpp and to a static function in the header to match
the current policy. The parameters order have also be changed to match the
other functions prototype.

drm_format_num_planes() is basically a lookup in the drm_format_info table
plus an access to the num_planes field of the appropriate entry.
Most drivers are using this function while having access to the entry
already, which means that we will perform an unnecessary lookup. Removing
the call to drm_format_num_planes is therefore more efficient.
Some drivers will not have access to that entry in the function, but in
this case the overhead is minimal (we just have to call drm_format_info()
to perform the lookup) and we can even avoid multiple, inefficient lookups
in some places that need multiple fields from the drm_format_info
structure.

The Amlogic G12A embeds the same Synopsys DW-HDMI Controller,
but with :
- a "backport" of the HDR signaling registers from more recent
DW-HDMI controllers, this will need a tweak since it's not
normally present on this version of the DW-HDMI controller
- A direct mapping of TOP and DW-HDMI registers instead of an
internal bus accessed using read/write registers
- Support for RX-SENSE, but not yet implemented
- Support for HDMI 2.1 Dynamic HDR, but not yet implemented
- Different registers mapping for the HDMI PHY setup
This patchs adds support for these changes while providing exact
same support as the previous GXBB, GXL & GXM SoCs.

While switching to the Common Clock Framework is still Work In Progress,
this patch adds the corresponding G12A HDMI PLL setup to be on-par
with the other SoCs support.
The G12A has only a single tweak about the high frequency setup,
where the HDMI PLL needs a specific setup to handle correctly the
5.94GHz DCO frequency.
Apart that, it handls ecorrectly all the other HDMI frequencies
and can achieve even better DMT clock frequency precision with
the larger fractional dividier width.

Amlogic G12A SoC supports the same set of Video Planes, but now
are handled by the new OSD plane blender module.
This patch uses the same VD1 plane for G12A, using the exact same scaler
and VD1 setup registers, except using the new blender register to

On Amlogic G12A SoC, the 2,97GHz PLL frequency is not stable enough
to provide a correct 297MHz pixel clock, so switch the PLL base
frequency with a /2 OD when the 297MHz pixel clock is requested.
This solves the issue on G12A and also works fine on GXBB, GXL & GXM.

DMT monitors does not necessarely report a maximum TMDS clock
in a VSDB EDID extension.
In this case, all modes are wrongly rejected, including
the DRM fallback EDID.
This patch only rejects modes whith clock > max_tmds_clock if
the max_tmds_clock is specified. This will only reject
4:2:0 HDMI2.0 modes, who reports a clock > max_tmds_clock.

meson_drv_unbind() doesn't unregister the IRQ handler, which can lead to
use-after-free if the IRQ fires after unbind:
[ 64.656876] Unable to handle kernel paging request at virtual address ffff000011706dbc
...
[ 64.662001] pc : meson_irq+0x18/0x30 [meson_drm]
I'm assuming that a similar problem could happen on the error path of
bind(), so uninstall the IRQ handler there as well.
