There's a large number of vm_get_page_prot(vma->vm_flags) invocations.
Make life easier by introducing vma_get_page_prot() parameterised by the
VMA.
This also makes converting vm_get_page_prot() to vma_flags_t easier.
Also update the userland VMA tests to reflect the change.
No functional change intended.

Callers of of_drm_find_panel() and drm_of_find_panel_or_bridge()
receive a pointer with no reference held, creating a window where
the panel device can be unregistered and freed between the lookup
and first use (e.g., drm_panel_prepare()).
Fix the lookup function by acquiring a reference with drm_panel_get()
before returning, under panel_lock. Callers are now responsible for
calling drm_panel_put() when they no longer need the pointer.
For bridge drivers that immediately wrap the panel in a panel_bridge
(which acquires its own reference), release the lookup reference right
after the bridge creation call.
For analogix-anx6345, which stores the panel for direct use, release
the reference in the i2c remove path.
For platform drivers using analogix_dp_core with a component lifecycle
(exynos_dp, rockchip analogix_dp), release the lookup reference in the
platform remove() function. The panel_bridge created during bind() holds
a separate reference that devm cleanup releases after remove() returns.
Also fix devm_drm_of_get_bridge() and drmm_of_get_bridge() in
bridge/panel.c itself, update a second batch of drivers calling
of_drm_find_panel() or drm_of_find_panel_or_bridge() to release the
lookup reference after wrapping the panel in a bridge, and handle the
cases where a panel is found but cannot be used, dropping the reference
immediately in those paths.

Simple KMS helper are deprecated since they only add an intermediate
layer between drivers and the atomic modesetting.
This patch removes the drm_simple_encoder_init() helper usage in the
rockchip drivers by open coding it and using the encoder atomic helpers
directly. This is a step to eventually get rid of this simple KMS helper,
once all drivers that use it have been converted.

With the introduction of the supported_formats member in the
dw-hdmi-qp platform data struct, drivers that have access to this
information should now set it.
Set it in the rockchip dw_hdmi_qp glue driver.
This allows this information to be passed down to the dw-hdmi-qp core,
which sets it in the bridge it creates, and consequently will allow the
common HDMI bridge code to act on it.

Switch between requested color formats by setting the right bus formats,
configuring the VO GRF registers, and setting the right output mode.
To do this, the encoder's atomic_check queries the bus format of the
first bridge, which was determined by the bridge chain recursive format
selection. Pick the input format if it's !FIXED, otherwise, pick the
output format.
The previously unused GRF register color format defines are redone as
well. Both RK3588 and RK3576 use the same defines; it didn't look like
this as there was a typo in the previously (unused) definition.

For RK3576 to be able to output YUV422 signals, it first needs to be
able to pick the right output mode in the display controller to do so.
The RK3576 hardware specifies different output formats depending on the
used display protocol.
Adjust the written register value based on the SoC and connector, so
other users of vcstate->output_mode don't have to care about this.

The Rockchip VOP2 video output driver has a "is_yuv_output" function,
which returns true when a given bus format is a YUV format, and false
otherwise.
This switch statement is lacking the bus format used for YUV422 10-bit.
Add the two component orderings of the YUV422 10-bit bus formats to the
switch statement.

- atomic_enable()
- dw_hdmi_rockchip_resume()

The HDMI block is currently hardcoded to expect RGB output from the
display controller. However, the VOP in some SoCs are capable of YCbCr
output to the HDMI block.
Read the negotiated bus format from the bridge state and propagate it to
the CRCT state in form of output mode and bus format. Treat the format
MEDIA_BUS_FMT_FIXED as RGB888 and reject any unsupported formats.
This has no inpact until dw-hdmi bridge is fully converted to a HDMI
bridge and also adds support for the "color format" connector property.

The HDMI helpers negotiated TMDS character rate and output bpc are
available from the connector state. Change the encoder helper from
mode_set() to atomic_mode_set() so these values can be used to configure
the HDMI PHY using phy_configure().
This has no impact until the dw-hdmi bridge is fully converted into a
HDMI bridge and HDMI helpers are used to assign hdmi.tmds_char_rate.

LAYERSEL_REGDONE_SEL
LAYERSEL_REGDONE_SEL mask of RK3568_OVL_CTRL register controls which
Video Port (VP) vsync latches the shared RK3568_OVL_{LAYER|PORT}_SEL
shadow registers into the active configuration.
rk3568_vop2_setup_layer_mixer() overwrites LAYERSEL_REGDONE_SEL to the
current VP ID before waiting for the previous VP layer configuration to
take effect. As a consequence, the previous VP vsync can no longer
trigger the latch, so the wait polls a value that might never appear.
Move the layer cfg done wait before the RK3568_OVL_CTRL write so the
previous VP vsync can still commit the pending configuration.

rk3568_vop2_setup_layer_mixer() waits for the previous Video Port (VP)
layer configuration to take effect before writing a new one to the
shared RK3568_OVL_LAYER_SEL shadow register. However, it passes
vop2->old_layer_sel to rk3568_vop2_wait_for_layer_cfg_done() as the
expected value, which at that point already contains the new VP layer.
This causes the wait to poll for a value that has not been written to
the shadow register yet, resulting in spurious timeouts when two
non-blocking atomic commits race:
rockchip-drm display-subsystem: [drm] *ERROR* wait layer cfg done timeout [...]
Pass the local old_layer_sel instead, which still holds the value
captured from vop2->old_layer_sel before it was overwritten, i.e. the
previous VP target that the hardware is expected to latch.

The VOP2 background color must be programmed with 10-bit precision,
using YUV format when the overlay operates in YUV mode, and RGB
otherwise.
Add the required RGB-to-YCbCr conversion logic, covering all color
spaces supported by the display controller: BT601L, BT601F, BT709L and
BT2020L.
Since the color is currently programmed to hardware on every atomic
commit, minimize the computation cost by splitting the work across the
two paths: in atomic_enable(), perform the conversion unconditionally
(the hardware state is unknown after power-on), while in atomic_flush(),
perform it only when the DRM property has actually changed.

The dw_hdmi-rockchip driver validates pixel clock rates against the
HDMI PHY's internal clock provider on certain SoCs like RK3328.
This is currently achieved by dereferencing hdmi->phy->dev.of_node
to obtain the provider node, which violates the Generic PHY API's
encapsulation (the goal is for struct phy to be an opaque pointer
with a hidden definition, to be interacted with only using API
functions or NULL pointer checks, for the case where optional variants
of phy_get() did not find a PHY).
Refactor dw_hdmi_rockchip_bind() to perform a manual phandle lookup
on the "hdmi" PHY index within the controller's DT node. This provides
a parallel path to the clock provider's OF node without relying on the
internal structure of the struct phy handle.

The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.
Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.
We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.
This patch was created using:
rg -l drm_atomic_state | \
xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'
