08fbd8a5fb drm/meson: overlay: fix build failure
The recent GCC compiler is very picky with the VD_H_START() and
AFBC_DEC_PIXEL_BGN_H() macros, triggering a runtime assert error as:

In function 'meson_overlay_setup_scaler_params',
    inlined from 'meson_overlay_atomic_update' at
drivers/gpu/drm/meson/meson_overlay.c:542:2:
./include/linux/compiler.h:392:38: error: call to
'__compiletime_assert_341' declared with attribute error: FIELD_PREP:
value too large for the field

drivers/gpu/drm/meson/meson_overlay.c:413:4: note: in expansion of macro
'AFBC_DEC_PIXEL_BGN_H'
  413 |    AFBC_DEC_PIXEL_BGN_H(hd_start_lines - afbc_left) |

./include/linux/compiler.h:392:38: error: call to
'__compiletime_assert_401' declared with attribute error: FIELD_PREP:
value too large for the field

It's not expected to overflow these fields, but the compiler did
find a case where it overflows.
We can safely ignore this, so mask the value with the field width.

e860785d57 drm/meson: overlay: setup overlay for Amlogic FBC
Setup the Amlogic FBC decoder for the VD1 video overlay plane.

The VD1 Amlogic FBC decoder is integrated in the pipeline like the
YUV pixel reading/formatter but used a direct memory address instead.

This adds support for the basic layout, and needs to calculate the content
body size since the header is allocated after.

17f64701ea drm/meson: viu: fix setting the OSD burst length in VIU_OSD1_FIFO_CTRL_STAT
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.

8976eeee8d drm/meson: add mode selection limits against specific SoC revisions
The Amlogic S805X/Y uses the same die as the S905X, but with more
limited graphics capabilities.

This adds a soc version detection adding specific limitations on the HDMI
mode selections.

Here, we limit to HDMI 1.2a max HDMI PHY clock frequency.

bd9ff7b521 drm/meson: Drop explicit drm_mode_config_cleanup call
It's right above the drm_dev_put().

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

Aside: This driver gets its devm_ stuff all wrong wrt drm_device and
anything hanging off that. Not the only one unfortunately.

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)

8496a2172d drm/meson: Add YUV420 output support
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.

In this case, it's worse because the variable name has the suffix
'_phys', which often indicates a phys_addr_t rather than dma_addr_t,
i.e. yet another incompatible type.

Change it to use consistent naming and avoid NULL.

68e2f64ee4 drm/meson: plane: add support for AFBC mode for OSD1 plane
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.

d1b5e41e13 drm/meson: Add AFBCD module driver
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.

43cb86799f drm: meson: venc: cvbs: fix CVBS mode matching
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.
