drm/fourcc: Add modifier definitions for describing Amlogic Video Framebuffer Compression
Amlogic uses a proprietary lossless image compression protocol and format
for their hardware video codec accelerators, either video decoders or
video input encoders.
It considerably reduces memory bandwidth while writing and reading
frames in memory.
The underlying storage is considered to be 3 components, 8bit or 10-bit
per component, YCbCr 420, single plane :
- DRM_FORMAT_YUV420_8BIT
- DRM_FORMAT_YUV420_10BIT
This modifier will be notably added to DMA-BUF frames imported from the V4L2
Amlogic VDEC decoder.
This introduces the basic layout composed of:
- a body content organized in 64x32 superblocks with 4096 bytes per
superblock in default mode.
- a 32 bytes per 128x64 header block
This layout is tranferrable between Amlogic SoCs supporting this modifier.
The Memory Saving option exist changing the layout superblock size to save memory when
using 8bit components pixels size.
Finally is also adds the Scatter Memory layout, meaning the header contains IOMMU
references to the compressed frames content to optimize memory access
and layout.
In this mode, only the header memory address is needed, thus the content
memory organization is tied to the current producer execution and cannot
be saved/dumped neither transferrable between Amlogic SoCs supporting this
modifier.

drm/atomic-helper: reset vblank on crtc reset
Only when vblanks are supported ofc.
Some drivers do this already, but most unfortunately missed it. This
opens up bugs after driver load, before the crtc is enabled for the
first time. syzbot spotted this when loading vkms as a secondary
output. Given how many drivers are buggy it's best to solve this once
and for all in shared helper code.
Aside from moving the few existing calls to drm_crtc_vblank_reset into
helpers (i915 doesn't use helpers, so keeps its own) I think the
regression risk is minimal: atomic helpers already rely on drivers
calling drm_crtc_vblank_on/off correctly in their hooks when they
support vblanks. And driver that's failing to handle vblanks after
this is missing those calls already, and vblanks could only work by
accident when enabling a CRTC for the first time right after boot.
Big thanks to Tetsuo for helping track down what's going wrong here.
There's only a few drivers which already had the necessary call and
needed some updating:
- komeda, atmel and tidss also needed to be changed to call
__drm_atomic_helper_crtc_reset() intead of open coding it
- tegra and msm even had it in the same place already, just code
motion, and malidp already uses __drm_atomic_helper_crtc_reset().
- Laurent noticed that rcar-du and omap open-code their crtc reset and
hence would actually be broken by this patch now. So fix them up by
reusing the helpers, which brings the drm_crtc_vblank_reset() back.
Only call left is in i915, which doesn't use drm_mode_config_reset,
but has its own fastboot infrastructure. So that's the only case where
we actually want this in the driver still.
I've also reviewed all other drivers which set up vblank support with
drm_vblank_init. After the previous patch fixing mxsfb all atomic
drivers do call drm_crtc_vblank_on/off as they should, the remaining
drivers are either legacy kms or legacy dri1 drivers, so not affected
by this change to atomic helpers.
v2: Use the drm_dev_has_vblank() helper.
v3: Laurent pointed out that omap and rcar-du used drm_crtc_vblank_off
instead of drm_crtc_vblank_reset. Adjust them too.
v4: Laurent noticed that rcar-du and omap open-code their crtc reset
and hence would actually be broken by this patch now. So fix them up
by reusing the helpers, which brings the drm_crtc_vblank_reset() back.
v5: also mention rcar-du and ompadrm in the proper commit message
above (Laurent).

drm/mipi-dbi: Remove ->enabled
The atomic helpers try really hard to not lose track of things,
duplicating enabled tracking in the driver is at best confusing.
Double-enabling or disabling is a bug in atomic helpers.
In the fb_dirty function we can just assume that the fb always exists,
simple display pipe helpers guarantee that the crtc is only enabled
together with the output, so we always have a primary plane around.
Now in the update function we need to be a notch more careful, since
that can also get called when the crtc is off. And we don't want to
upload frames when that's the case, so filter that out too.

drm: bridge: dw-hdmi: Pass private data pointer to .configure_phy()
The .configure_phy() operation takes a dw_hdmi_plat_data pointer as a
context argument. This differs from .mode_valid() that takes a custom
private context pointer, causing possible confusion. Make the
dw_hdmi_plat_data operations more consistent by passing the private
context pointer to .configure_phy() as well.

drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()
Platform glue drivers for dw_hdmi may need to access device-specific
data from their .mode_valid() implementation. They currently have no
clean way to do so, and one driver hacks around it by accessing the
dev_private data of the drm_device retrieved from the connector.
Add a priv_data void pointer to the dw_hdmi_plat_data structure, and
pass it to the .mode_valid() function.

drm: bridge: Pass drm_display_info to drm_bridge_funcs .mode_valid()
When validating a mode, bridges may need to do so in the context of a
display, as specified by drm_display_info. An example is the meson
dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to
perform clock calculations.
Bridges that need the display info currently retrieve it from the
drm_connector created by the bridge. This gets in the way of moving
connector creation out of bridge drivers. To make this possible, pass
the drm_display_info to drm_bridge_funcs .mode_valid().
Changes to the bridge drivers have been performed with the following
coccinelle semantic patch and have been compile-tested.

drm: bridge: adv7511: Implement bridge connector operations
Implement the bridge connector-related .get_edid(), .detect() and
.hpd_notify() operations, and report the related bridge capabilities.
Output status detection is implemented using the same backend as for the
DRM connector, but requires making mode retrieval at detection time
optional as no pointer to the connector is available to the bridge
.detect() operation. The reason for the need to retrieve modes at
detection time is unclear to me, and this may benefit from further
refactoring of hot plug handling code.
Hot plug detection is notified through the bridge HPD notification
framework when the bridge is used without creating a connector, and
falls back to the existing implementation otherwise. CEC handling of
disconnection is handled in the new .hpd_notify() operation in the new
code path.
