Daniel Vetter cde4c44d87 drm: drop _mode_ from drm_mode_connector_attach_encoder
Again to align with the usual prefix of just drm_connector_. Again
done with sed + manual fixup for indent issues.

Russell King 070473bcf7 drm: add missing ctx argument to plane transitional helpers
In commits:
34a2ab5e06 ("drm: Add acquire ctx parameter to ->update_plane")
1931529448 ("drm: Add acquire ctx parameter to ->plane_disable")

a pointer to a drm_modeset_acquire_ctx structure was added as an
argument to the method prototypes.  The transitional helpers are
supposed to be directly plugged in as implementations of these
methods, but doing so generates a warning.  Add the missing
argument.

A number of buggy users were added for drm_plane_helper_disable()
which need to be fixed up for this change, which we do by passing
a NULL ctx argument.

Fixes: 1931529448 ("drm: Add acquire ctx parameter to ->plane_disable")

Ville Syrjälä 1add20eb00 drm/arc: Stop consulting plane->fb
We want to stop using plane->fb with atomic driver, so stop looking at
it.

I have no idea what this code is trying to achieve. There is no
corresponding check in the enable path. Also since
arc_pgu_set_pxl_fmt() will anyway oops if there is no fb I'm going
to assuming that I can just remove the check entirely. There seems
to be a general shortage of .atomic_check() in this driver...

Daniel Vetter b46310eecd drm/arcpgu: remove drm_encoder_slave
drm_encoder_slave is the old way to write bridge drivers, for i2c
bridges only. It's deprecated, and definitely should not be used in
new drivers. This has absolutely nothing to do with the new bridge
driver infrastructure implemented by drm_bridge.

What's even strange is that arcpgu doesn't even use any of this, it
really only wants a plain normal drm_encoder. Nuke all the surplus
real estate.

v2: Actually git add after compile testing ...

v3: Clarify commit message and stop including drm_encoder_slave.h.

Jose Abreu 22d0be2a55 drm: arcpgu: Allow some clock deviation in crtc->mode_valid() callback
Currently we expect that clock driver produces the exact same value
as we are requiring. There can, and will, be some deviation
however so we need to take that into account instead of just
rejecting the mode.

According to the HDMI spec we have a max of +-0.5% for the pixel clock
frequency deviation. Lets take that into an advantage and use it to
calculate how much deviation we can support.

Jose Abreu a8f8fb2057 drm: arcpgu: Fix mmap() callback
Now that ARC properly supports DMA mmap() we can use the standard
CMA helper to map dumb buffers. This makes ARC PGU works with
standard DRM consumer applications like, for example, mpv/mplayer
via DRM. While at it, use the DEFINE_DRM_GEM_CMA_FOPS() helper.

This fixes the use of dumb buffers.

Now that we have a callback to check if crtc supports a given mode
we can use it in arcpgu so that we restrict the number of probbed
modes to the ones we can actually display.

This is specially useful because arcpgu crtc is responsible to set
a clock value in the commit() stage but unfortunatelly this clock
does not support all the needed ranges.

Also, remove the atomic_check() callback as mode_valid() callback
will be called before.

Gabriel Krisman Bertazi e4563f6ba7 drm: Rely on mode_config data for fb_helper initialization
Instead of receiving the num_crts as a parameter, we can read it
directly from the mode_config structure.  I audited the drivers that
invoke this helper and I believe all of them initialize the mode_config
struct accordingly, prior to calling the fb_helper.

I used the following coccinelle hack to make this transformation, except
for the function headers and comment updates.  The first and second
rules are split because I couldn't find a way to remove the unused
temporary variables at the same time I removed the parameter.

Changes since v1:
 - Rebased on top of the tip of drm-misc-next.
 - Remove mention to sti since a proper fix got merged.
