rockchip_drm_endpoint_is_subdriver() may also return error codes.
For example if the target-node is in the disabled state, so no
platform-device is getting created for it.
In that case current code would count that as external rgb device,
which in turn would make probing the rockchip-drm device fail.
So only count the target as rgb device if the function actually
returns 0.

drm_fb_helper_{add,remove}_one_connector() and
drm_fb_helper_single_add_all_connectors() are dummy functions now
and serve no purpose. Hence remove their calls.
This is the preparatory step for removing the
drm_fb_helper_{add,remove}_one_connector() functions from
drm_fb_helper.h
This removal is done using below sementic patch and unused variable
compilation warnings are fixed manually.

Most bridge drivers create a DRM connector to model the connector at the
output of the bridge. This model is historical and has worked pretty
well so far, but causes several issues:
- It prevents supporting more complex display pipelines where DRM
connector operations are split over multiple components. For instance a
pipeline with a bridge connected to the DDC signals to read EDID data,
and another one connected to the HPD signal to detect connection and
disconnection, will not be possible to support through this model.
- It requires every bridge driver to implement similar connector
handling code, resulting in code duplication.
- It assumes that a bridge will either be wired to a connector or to
another bridge, but doesn't support bridges that can be used in both
positions very well (although there is some ad-hoc support for this in
the analogix_dp bridge driver).
In order to solve these issues, ownership of the connector should be
moved to the display controller driver (where it can be implemented
using helpers provided by the core).
Extend the bridge API to allow disabling connector creation in bridge
drivers as a first step towards the new model. The new flags argument to
the bridge .attach() operation allows instructing the bridge driver to
skip creating a connector. Unconditionally set the new flags argument to
0 for now to keep the existing behaviour, and modify all existing bridge
drivers to return an error when connector creation is not requested as
they don't support this feature yet.
The change is based on the following semantic patch, with manual review
and edits.

While the common case is that the dsi controller uses an internal dphy,
accessed through the phy registers inside the dsi controller, there is
also the possibility to use a separate dphy from a different vendor.
One such case is the Rockchip px30 that uses a Innosilicon Mipi dphy,
so add the support for handling such a constellation, including the pll
also getting generated inside that external phy.

The timing values for dw-dsi are often dependent on the used display and
according to Philippe Cornu will most likely also depend on the used phy
technology in the soc-specific implementation.
To solve this and allow specific implementations to define them as needed
add a new get_timing callback to phy_ops and call this from the dphy_timing
function to retrieve the necessary values for the specific mode.
Right now this handles the hs2lp + lp2hs where Rockchip SoCs need handling
according to the phy speed, while STM seems to be ok with static values.
changes in v5:
- rebase on 5.5-rc1
- merge into px30 dsi series to prevent ordering conflicts
changes in v4:
- rebase to make it directly fit on top of drm-misc-next after all
changes in v3:
- check existence of phy_ops->get_timing in __dw_mipi_dsi_probe()
- emit actual error when get_timing() call fails
- add tags from Philippe and Yannick
changes in v2:
- add driver-specific handling, don't force all bridge users to use
the same timings, as suggested by Philippe

To facilitate moving connector creation to display drivers,
decouple the drm_connector from drm_panel.
This patch adds a connector argument to drm_panel_get_modes().
All users of drm_panel_get_modes() already had the connector
available, so updating users was trivial.
With this patch drm_panel no longer keeps a reference to the drm_connector.

Add an optional CRTC gamma LUT support, and enable it on RK3288.
This is currently enabled via a separate address resource,
which needs to be specified in the devicetree.
The address resource is required because on some SoCs, such as
RK3288, the LUT address is after the MMU address, and the latter
is supported by a different driver. This prevents the DRM driver
from requesting an entire register space.
The current implementation works for RGB 10-bit tables, as that
is what seems to work on RK3288.

I'm embarassed to say that even though I've touched
vop_crtc_mode_fixup() twice and I swear I tested it, there's still a
stupid glaring bug in it. Specifically, on veyron_minnie (with all
the latest display timings) we want to be setting our pixel clock to
66,666,666.67 Hz and we tell userspace that's what we set, but we're
actually choosing 66,000,000 Hz. This is confirmed by looking at the
clock tree.
The problem is that in drm_display_mode_from_videomode() we convert
from Hz to kHz with:
dmode->clock = vm->pixelclock / 1000;
...and drm_display_mode_from_videomode() is called from panel-simple
when we have an "override_mode" like we do on veyron_minnie. See
commit 123643e5c40a ("ARM: dts: rockchip: Specify
rk3288-veyron-minnie's display timings").
...so when the device tree specifies a clock of 66666667 for the panel
then DRM translates that to 66666000. The clock framework will always
pick a clock that is _lower_ than the one requested, so it will refuse
to pick 66666667 and we'll end up at 66000000.
While we could try to fix drm_display_mode_from_videomode() to round
to the nearest kHz and it would fix our problem, it wouldn't help if
the clock we actually needed was 60,000,001 Hz. We could
alternatively have DRM always round up, but maybe this would break
someone else who already baked in the assumption that DRM rounds down.
Specifically note that clock drivers are not consistent about whether
they round up or round down when you call clk_set_rate(). We know how
Rockchip's clock driver works, but (for instance) you can see that on
most Qualcomm clocks the default is clk_rcg2_ops which rounds up.
Let's solve this by just adding 999 Hz before calling
clk_round_rate(). This should be safe and work everywhere. As
discussed in more detail in comments in the commit, Rockchip's PLLs
are configured in a way that there shouldn't be another PLL setting
that is only a few kHz off so we won't get mixed up.
NOTE: if this is picked to stable, it's probably easiest to first pick
commit 527e4ca3b6d1 ("drm/rockchip: Base adjustments of the mode based
on prev adjustments") which shouldn't hurt in stable.

there is anything outstanding so next week should just be fixes, but
we'll see if I missed anything. I landed some fixes earlier in the

Currently the self refresh idle timer is a const set by the crtc. This
is fine if the self refresh entry/exit times are well-known for all
panels used on that crtc. However panels and workloads can vary quite a
bit, and a timeout which works well for one doesn't work well for
another.
In the extreme, if the timeout is too short we could get in a situation
where the self refresh exits are taking so long we queue up a self refresh
entry before the exit commit is even finished.
This patch changes the idle timeout to a moving average of the entry
times + a moving average of exit times + the crtc constant.
This patch was tested on rockchip, with a kevin CrOS panel the idle
delay averages out to about ~235ms (35 entry + 100 exit + 100 const). On
the same board, the bob panel idle delay lands around ~340ms (90 entry
+ 150 exit + 100 const).
WRT the dedicated mutex in self_refresh_data, it would be nice if we
could rely on drm_crtc.mutex to protect the average times, but there are
a few reasons why a separate lock is a better choice:
- We can't rely on drm_crtc.mutex being held if we're doing a nonblocking
commit
- We can't grab drm_crtc.mutex since drm_modeset_lock() doesn't tell us
whether the lock was already held in the acquire context (it eats
-EALREADY), so we can't tell if we should drop it or not
- We don't need such a heavy-handed lock for what we're trying to do,
commit ordering doesn't matter, so a point-of-use lock will be less
contentious

Pull LED updates from Jacek Anaszewski:
"In this cycle we've finally managed to contribute the patch set
sorting out LED naming issues. Besides that there are many changes
scattered among various LED class drivers and triggers.
LED naming related improvements:
- add new 'function' and 'color' fwnode properties and deprecate
'label' property which has been frequently abused for conveying
vendor specific names that have been available in sysfs anyway
- introduce a set of standard LED_FUNCTION* definitions
- introduce a set of standard LED_COLOR_ID* definitions
- add a new {devm_}led_classdev_register_ext() API with the
capability of automatic LED name composition basing on the
properties available in the passed fwnode; the function is
backwards compatible in a sense that it uses 'label' data, if
present in the fwnode, for creating LED name
- add tools/leds/get_led_device_info.sh script for retrieving LED
vendor, product and bus names, if applicable; it also performs
basic validation of an LED name
- update following drivers and their DT bindings to use the new LED
registration API:
- leds-an30259a, leds-gpio, leds-as3645a, leds-aat1290, leds-cr0014114,
leds-lm3601x, leds-lm3692x, leds-lp8860, leds-lt3593, leds-sc27xx-blt
Other LED class improvements:
- replace {devm_}led_classdev_register() macros with inlines
- allow to call led_classdev_unregister() unconditionally
- switch to use fwnode instead of be stuck with OF one
LED triggers improvements:
- led-triggers:
- fix dereferencing of null pointer
- fix a memory leak bug
- ledtrig-gpio:
- GPIO 0 is valid
Drop superseeded apu2/3 support from leds-apu since for apu2+ a newer,
more complete driver exists, based on a generic driver for the AMD
SOCs gpio-controller, supporting LEDs as well other devices:
- drop profile field from priv data
- drop iosize field from priv data
- drop enum_apu_led_platform_types
- drop superseeded apu2/3 led support
- add pr_fmt prefix for better log output
- fix error message on probing failure
Other misc fixes and improvements to existing LED class drivers:
- leds-ns2, leds-max77650:
- add of_node_put() before return
- leds-pwm, leds-is31fl32xx:
- use struct_size() helper
- leds-lm3697, leds-lm36274, leds-lm3532:

The drm panel bridge creates a connector using a connector type
explicitly passed by the display controller or bridge driver that
instantiates the panel bridge. Now that drm_panel reports its connector
type, we can use it to avoid passing an explicit (and often incorrect)
connector type to drm_panel_bridge_add() and
devm_drm_panel_bridge_add().
Several drivers report incorrect or unknown connector types to
userspace. Reporting a different type may result in a breakage. For that
reason, rename (devm_)drm_panel_bridge_add() to
(devm_)drm_panel_bridge_add_typed(), and add new
(devm_)drm_panel_bridge_add() functions that use the panel connector
type. Update all callers of (devm_)drm_panel_bridge_add() to the _typed
function, they will be converted one by one after testing.
The panel drivers have been updated with the following Coccinelle
semantic patch, with manual inspection and fixes to indentation.

In commit fe64ba5c6323 ("drm/rockchip: Resume DP early") we moved
resume to be early but left suspend at its normal time. This seems
like it could be OK, but casues problems if a suspend gets interrupted
partway through. The OS only balances matching suspend/resume levels.
...so if suspend was called then resume will be called. If suspend
late was called then resume early will be called. ...but if suspend
was called resume early might not get called. This leads to an
unbalance in the clock enables / disables.
Lets take the simple fix and just move suspend to be late to match.
This makes the PM core take proper care in keeping things balanced.

Instead of rolling our own implementation for tracking when PSR should
be [in]active, use the new self refresh helpers to do the heavy lifting.
Changes in v2:
- updated to reflect changes made in the helpers
Changes in v3:
- use the new atomic hooks to inspect crtc state instead of needing conn state (Daniel)
Changes in v4:
- Use Laurent's get_new_connector_for_encoder helper (Daniel)
- Exit vop disable early if it's already off
Changes in v5:
- Rebase on latest drm-misc-next
- Resolve conflict with s/edp_vsc_psr/dp_sdp/ rename
- Resolve conflict with drm_atomic.h header inclusion
