ecfdedd7da drm/omap: force runtime PM suspend on system suspend
Use SET_LATE_SYSTEM_SLEEP_PM_OPS in DSS submodules to force runtime PM
suspend and resume.

We use suspend late version so that omapdrm's system suspend callback is
called first, as that will disable all the display outputs after which
it's safe to force DSS into suspend.

12c683e12c drm: bridge: Pass drm_display_info to drm_bridge_funcs .mode_valid()
When validating a mode, bridges may need to do so in the context of a
display, as specified by drm_display_info. An example is the meson
dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to
perform clock calculations.

Bridges that need the display info currently retrieve it from the
drm_connector created by the bridge. This gets in the way of moving
connector creation out of bridge drivers. To make this possible, pass
the drm_display_info to drm_bridge_funcs .mode_valid().

Changes to the bridge drivers have been performed with the following
coccinelle semantic patch and have been compile-tested.

@ rule1 @
identifier funcs;
identifier fn;

 struct drm_bridge_funcs funcs = {
 	...,
 	.mode_valid = fn

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

9cd39de4db drm/omap: change default signal polarities and drives
If the given videomode does not specify DISPLAY_FLAG_* for the specific
signal property, the driver used a default value. These defaults were
never thought through, as the expectation was that all the DISPLAY_FLAGS
are always set explicitly.

With DRM bridge and panel drivers this is not the case, and while that
issue should be resolved in the future, it's still good to have sane
signal defaults.

This patch changes the defaults to what the hardware has as reset
defaults. Also, based on my experience, I think they make sense and are
more likely correct than the defaults without this patch.

cef7663003 drm/omap: Prepare DSS for probing without legacy platform data
In order to probe display subsystem (DSS) components with ti-sysc
interconnect target module without legacy platform data and using
devicetree, we need to update dss probing a bit.

In the device tree, we will be defining the data also for the interconnect
target modules as DSS really is a private interconnect. There is some
information about that in 4460 TRM in "Figure 10-3. DSS Integration" for
example where it mentions "32-bit interconnect (SLX)".

The changes we need to make are:

1. Parse also device tree subnodes for the compatible property fixup

2. Update the component code to consider device tree subnodes

1edc1a1cbe drm/omap: hdmi5: Rework EDID read to isolate data read
In preparation of adding DRM bridge support to the hdmi5 encoder code,
rework the EDID read to isolate data read.

The hdmi_read_edid() function is the main entry point. It performs all
initialisation steps required prior to reading the EDID (such as
ensuring the device is powered on), as well as corresponding cleanup
steps afterwards. EDID read itself is handled by hdmi_read_edid_data()
that calls the hdmi5_core_ddc_read() function to read individual blocks.

This new code architecture will allow reusing hdmi_read_edid() and
hdmi5_core_ddc_read() for the drm_bridge EDID read implementation, while
swapping out hdmi_read_edid_data() for the DRM drm_do_get_edid()
function.

326a1166ca drm/omap: Add infrastructure to support drm_bridge local to DSS outputs
In order to support drm_bridge-based pipeline, the internal HDMI
encoders will need to expose the EDID read operation through the
drm_bridge API, and thus to expose a drm_bridge instance corresponding
to the encoder. The HDMI encoders are however handled as omap_dss_device
instances, which conflicts with this requirement.

In order to move forward with the drm_bridge transition, add support for
creating drm_bridge instances local to DSS outputs. If a local bridge is
passed to the omapdss_device_init_output() function, it is used as the
first bridge in the chain, and the omap_dss_device.next_bridge field is
set to the next bridge for the use of the internal encoders' bridges.

8b185cf7eb drm/omapdrm: use BUG_ON macro for error debugging.

Issue found using coccinelle.
