This function is for panel_bridge instances only. The silent return when
invoked on other bridges might hide actual errors, so avoid them to go
unnoticed.

drm_panel_bridge_remove() reads bridge->funcs to find out whether this is a
panel bridge or another kind of bridge. drm_bridge_is_panel() is made
exactly for that, so use it.

If the clock mhdp->clk was not enabled in cdns_mhdp_probe(), it should not
be disabled in any path.
The return value of clk_prepare_enable() is not checked. If mhdp->clk was
not enabled, it may be disabled in the error path of cdns_mhdp_probe()
(e.g., if cdns_mhdp_load_firmware() fails) or in cdns_mhdp_remove() after
a successful cdns_mhdp_probe() call.
Use the devm_clk_get_enabled() helper function to ensure proper call
balance for mhdp->clk.

PHY_CMN_CLK_CFG1 register has four fields being used in the driver: DSI
clock divider, source of bitclk and two for enabling the DSI PHY PLL
clocks.
dsi_7nm_set_usecase() sets only the source of bitclk, so should leave
all other bits untouched. Use newly introduced
dsi_pll_cmn_clk_cfg1_update() to update respective bits without
overwriting the rest.
While shuffling the code, define and use PHY_CMN_CLK_CFG1 bitfields to
make the code more readable and obvious.

PHY_CMN_CLK_CFG0 register is updated by the PHY driver and by two
divider clocks from Common Clock Framework:
devm_clk_hw_register_divider_parent_hw(). Concurrent access by the
clocks side is protected with spinlock, however driver's side in
restoring state is not. Restoring state is called from
msm_dsi_phy_enable(), so there could be a path leading to concurrent and
conflicting updates with clock framework.
Add missing lock usage on the PHY driver side, encapsulated in its own
function so the code will be still readable.

What used to be the input_10_bits boolean - feeding into the lowest
bit of DSC_ENC - on MSM downstream turned into an accidental OR with
the full bits_per_component number when it was ported to the upstream
kernel.
On typical bpc=8 setups we don't notice this because line_buf_depth is
always an odd value (it contains bpc+1) and will also set the 4th bit
after left-shifting by 3 (hence this |= bits_per_component is a no-op).
Now that guards are being removed to allow more bits_per_component
values besides 8 (possible since commit 49fd30a7153b ("drm/msm/dsi: use
DRM DSC helpers for DSC setup")), a bpc of 10 will instead clash with
the 5th bit which is convert_rgb. This is "fortunately" also always set
to true by MSM's dsi_populate_dsc_params() already, but once a bpc of 12
starts being used it'll write into simple_422 which is normally false.
To solve all these overlaps, simply replicate downstream code and only
set this lowest bit if bits_per_component is equal to 10. It is unclear
why DSC requires this only for bpc=10 but not bpc=12, and also notice
that this lowest bit wasn't set previously despite having a panel and
patch on the list using it without any mentioned issues.

Widebus allows the DP controller to operate in 2 pixel per clock mode.
The mode validation logic validates the mode->clock against the max
DP pixel clock. However the max DP pixel clock limit assumes widebus
is already enabled. Adjust the mode validation logic to only compare
the adjusted pixel clock which accounts for widebus against the max DP
pixel clock. Also fix the mode validation logic for YUV420 modes as in
that case as well, only half the pixel clock is needed.

Since we have all the necessary bits in intel_connector.c might
as well always initialize the modeset_retry_work for every connector.
Avoids yet another init function you have to remember to call.

Most of the modeset retry stuff looks to be entirely generic,
and so there doesn't seem to any reason to keep it in intel_dp.c.
Move the generic bits into intel_connector.c.

The current code tries to handle joiner vs. Y planes completely
independently. That does not really work since each pipe selects
its Y planes completely independently, and any plane pulled into
the state by one of the secondary pipes needs to have the plane
on the primary pipe also included in the state (for the uapi
state copy). The current code sometimes forgets to pull in planes
that we need, leading to weird things like the Y<->UV plane link
only getting torn down from one side but not the other.
Remedy the situation by pulling in the exact same set planes
on all the joined pipes. To calculate the set we simply
look through each joined crtc and any plane in the state gets
added to the set. However due to the way the Y plane selection
works we may not be able to determine the set in one go. One
plane on one pipe may pull in a Y plane, which may have to pull
in another plane because it's not acting in the same role on
another pipe, etc. The simple approach taken here is to keep
looping and adding planes to the set until it stops growing.
I suppose if we tracked more of this Y plane stuff in the
crtc state rather than the plane state we might be able to
do it in one go. But this works, and it's not going to loop
for long anyway since we only have so many pipes and Y planes
to consider.

Any active plane needs to have its crtc included in the atomic
state. For planes enabled via uapi that is all handler in the core.
But when we use a plane for joiner the uapi code things the plane
is disabled and therefore doesn't have a crtc. So we need to pull
those in by hand. We do it first thing in
intel_joiner_add_affected_crtcs() so that any newly added crtc will
subsequently pull in all of its joined crtcs as well.
The symptoms from failing to do this are:
- duct tape in the form of commit 1d5b09f8daf8 ("drm/i915: Fix NULL
ptr deref by checking new_crtc_state")
- the plane's hw state will get overwritten by the disabled
uapi state if it can't find the uapi counterpart plane in
the atomic state from where it should copy the correct state
