e7642f3585 backlight: drop EARLY_EVENT_BLANK support
There was no users left - so drop the code to support EARLY_EVENT_BLANK.
This patch removes the support in backlight,
and drop the notifier in fbmem.

That EARLY_EVENT_BLANK is not used can be verified that no driver set any of:

    lcd_ops.early_set_power()
    lcd_ops.r_early_set_power()

Noticed while browsing backlight code for other reasons.

v2:
- Fix changelog to say "EARLY_EVENT_BLANK" (Daniel)

05103ea9a3 drm/vblank: drop use of DRM_WAIT_ON()
DRM_WAIT_ON() is from the deprecated drm_os_linux header and
the modern replacement is the wait_event_*.

The return values differ, so a conversion is needed to
keep the original interface towards userspace.
Introduced a switch/case to make code obvious.

Analysis from Michel Dänzer:

The waiting condition rely on all relevant places where vblank_count
is modified calls wake_up(&vblank->queue).

drm_handle_vblank():
- Calls wake_up(&vblank->queue)

drm_vblank_enable():
- There is no need here because there can be no sleeping waiters
  in the queue, because vblank->enabled == false immediately
  terminates any waits.

drm_crtc_accurate_vblank_count():
- This is called from interrupt handlers, at least from
  amdgpu_dm.c:dm_pflip_high_irq(). Not sure it needs to wake up
  the queue though, the driver should call
  drm_(crtc_)_handle_vblank anyway.

drm_vblank_disable_and_save():
- It can be called from an interrupt, via drm_handle_vblank ->
  vblank_disable_fn. However, the only place where
  drm_vblank_disable_and_save can be called with sleeping waiters
  in the queue is in drm_crtc_vblank_off, which wakes up the queue
  afterwards (which terminates all waits, because
  vblank->enabled == false at this point).

v3:
- Added analysis to changelog from Michel Dänzer
- Moved return result handling inside if (req_seq != seq) (Daniel V)
- Reused more of the former logic - resulting in simpler code
- Dropped Reviewed-by from Sean Paul as this is a new implementation

v2:
- Fix so the case where req_seq equals seq was handled properly
- quick hack to check if IGT became happy
- Only sent to igt, not to dri-devel

8965ad8433 drm/komeda: Enable dual-link support
Komeda HW can support dual-link which splits display frame to two halves
(left/link0, right/link1) and output them by two output links.
Due to the halved pixel rate of each link, the pxlclk of dual-link can be
reduced two times compare with single-link.

For enabling dual-link:
- The DT need to configure two output-links for the pipeline node.
- Komeda enable dual-link when both link0 and link1 have been connected.

Example of how the pipeline node will look like for dual-link setup

pipe0: pipeline@0 {
	clocks = <&fpgaosc2>;
	clock-names = "pxclk";
	reg = <0>;

	#address-cells = <1>;
	#size-cells = <0>;

	port@0 {
		reg = <0>;

		#address-cells = <1>;
		#size-cells = <0>;
		dp0_pipe0_link0: endpoint@0 {
			reg = <0>;
			remote-endpoint = <&dlink_connector_in0>;

		};
		dp0_pipe0_link1: endpoint@1 {
			reg = <1>;
			remote-endpoint = <&dlink_connector_in1>;
		};

100163df42 drm: Add drm_connector_init() variant with ddc
Allow passing ddc adapter pointer to the init function. Even if
drm_connector_init() sometime in the future decides to e.g. memset() all
connector fields to zeros, the newly added function ensures that at its
completion the ddc member of connector is correctly set.

e1a29c6c59 drm: Add ddc link in sysfs created by drm_connector
Add generic code which creates symbolic links in sysfs, pointing to ddc
interface used by a particular video output. For example:

ls -l /sys/class/drm/card0-HDMI-A-1/ddc
lrwxrwxrwx 1 root root 0 Jun 24 10:42 /sys/class/drm/card0-HDMI-A-1/ddc \
	-> ../../../../soc/13880000.i2c/i2c-2

This makes it easy for user to associate a display with its ddc adapter
and use e.g. ddcutil to control the chosen monitor.

This patch adds an i2c_adapter pointer to struct drm_connector. Particular
drivers can then use it instead of using their own private instance. If a
connector contains a ddc, then create a symbolic link in sysfs.
