1e0f66420b drm/display: Introduce a DRM display-helper module
Replace the DP-helper module with a display-helper module. The
support for DisplayPort becomes an internal option that drivers
have to select. Update all related Kconfig and Makefile rules.

Besides the existing code for DisplayPort, the new module will
contain helpers for other video-output standards, such as HDMI.
Drivers will have to select their required video-output helpers.

Linking all display-related code into a single module avoids the
proliferation of small kernel modules.

The module parameters drm_dp_cec_unregister_delay, dp_aux_i2c_speed_khz,
and dp_aux_i2c_transfer_size are moving from the drm_dp_helper namespace
to drm_display_helper.

v2:
	* mention module parameters in commit message (Javier)
	* distiguish between display module and DP support in Kconfig
	* update Makefile rules for DP helpers
	* move Kconfig rules into separate file under display/

da68386d9e drm: Rename dp/ to display/
Rename dp/ to display/ to account for additional display-related
helpers, such as HDMI. Update all related include statements. No
functional changes.

Various drivers, such as i915 and amdgpu, use similar naming scheme
by putting code for video-output standards into a local display/
directory. The new directory's name is aligned with this convention.

83c784e700 drm/panel: lvds: Use bus_flags from DT panel-timing property
This driver currently rewrites bus_flags based solely on the value of
DT property 'data-mirror' and ignores bus_flags which might have been
set in DT panel-timing node. Specificaly, the 'de-active' DT property
sets DRM_BUS_FLAG_DE_ bus_flags.

Since of_get_drm_panel_display_mode() conveniently parses the bus_flags
out of DT panel-timing property, just ORR them with bus_flags inferred
from 'data-mirror' DT property and use the result as panel bus_flags.

This fixes handling of panels with 'panel-timing { de-active = <1>; };'.

03fa454bb6 drm/panel: lvds: Simplify mode parsing
The mode parsing is currently implemented in three steps:
of_get_display_timing() - DT panel-timing to struct display_timing
videomode_from_timing() - struct display_timing to struct videomode
drm_display_mode_from_videomode() - struct videomode to struct drm_display_mode

Replace all that with simple of_get_drm_panel_display_mode() call,
which already populates struct drm_display_mode and then duplicate
that mode in panel_lvds_get_modes() each time, since the mode does
not change.

Nice bonus is the bus_flags parsed by of_get_drm_panel_display_mode()
out of panel-timing DT node, which is used in subsequent patch to fix
handling of 'de-active' DT property.

drm/panel: innolux-ej030na and abt-y030xx067a: add .enable and .disable
Following the introduction of bridge_atomic_enable in the ingenic
drm driver, the crtc is enabled between .prepare and .enable, if
it exists. Add it so the backlight is only enabled after the crtc is, to
avoid graphical issues.

As we're moving the "sleep out" command out of the init sequence
into .enable for the ABT, we need to switch the regmap cache
to REGCACHE_FLAT to be able to use regmap_set_bits, given this
panel registers are write-ony and read as 0.

ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

3c3384050d drm: Don't make DRM_PANEL_BRIDGE dependent on DRM_KMS_HELPERS
Fix a number of undefined references to drm_kms_helper.ko in
drm_dp_helper.ko:

  arm-suse-linux-gnueabi-ld: drivers/gpu/drm/dp/drm_dp_mst_topology.o: in function `drm_dp_mst_duplicate_state':

  drm_dp_mst_topology.c:(.text+0x82e0): undefined reference to `drm_kms_helper_hotplug_event'

This happens if panel-edp.ko has been configured with

  DRM_PANEL_EDP=y
  DRM_DP_HELPER=y
  DRM_KMS_HELPER=m

which builds DP helpers into the kernel and KMS helpers sa a module.
Making DRM_PANEL_EDP select DRM_KMS_HELPER resolves this problem.

To avoid a resulting cyclic dependency with DRM_PANEL_BRIDGE, don't
make the latter depend on DRM_KMS_HELPER and fix the one DRM bridge
drivers that doesn't already select DRM_KMS_HELPER. As KMS helpers
cannot be selected directly by the user, config symbols should avoid
depending on it anyway.

fc1b6ef7bf drm/panel: simple: Fix Innolux G070Y2-L01 BPP settings
The Innolux G070Y2-L01 supports two modes of operation:
1) FRC=Low/NC ... MEDIA_BUS_FMT_RGB666_1X7X3_SPWG ... BPP=6
2) FRC=High ..... MEDIA_BUS_FMT_RGB888_1X7X4_SPWG ... BPP=8

Currently the panel description mixes both, BPP from 1) and bus
format from 2), which triggers a warning at panel-simple.c:615.

Pick the later, set bpp=8, fix the warning.

6ed19359d6 drm/panel-edp: Allow querying the detected panel via debugfs
Recently we added generic "edp-panel"s probed by EDID. To support
panels in this way we look at the panel ID in the EDID and look up the
panel in a table that has power sequence timings. If we find a panel
that's not in the table we will still attempt to use it but we'll use
conservative timings. While it's likely that these conservative
timings will work for most nearly all panels, the performance of
turning the panel off and on suffers.

We'd like to be able to reliably detect the case that we're using the
hardcoded timings without relying on parsing dmesg. This allows us to
implement tests that ensure that no devices get shipped that are
relying on the conservative timings.

Let's add a new debugfs entry to panel devices. It will have one of:
* UNKNOWN - We tried to detect a panel but it wasn't in our table.
* HARDCODED - We're not using generic "edp-panel" probed by EDID.
* A panel name - This is the name of the panel from our table.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.
