drm: Split out drm_probe_helper.h

2019-01-24T12:20:42+00:00

Having the probe helper stuff (which pretty much everyone needs) in
the drm_crtc_helper.h file (which atomic drivers should never need) is
confusing. Split them out.

To make sure I actually achieved the goal here I went through all
drivers. And indeed, all atomic drivers are now free of
drm_crtc_helper.h includes.

v2: Make it compile. There was so much compile fail on arm drivers
that I figured I'll better not include any of the acks on v1.

v3: Massive rebase because i915 has lost a lot of drmP.h includes, but
not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h
there was still one, which this patch largely removes. Which means
rolling out lots more includes all over.

This will also conflict with ongoing drmP.h cleanup by others I
expect.

v3: Rebase on top of atomic bochs.

v4: Review from Laurent for bridge/rcar/omap/shmob/core bits:
- (re)move some of the added includes, use the better include files in
  other places (all suggested from Laurent adopted unchanged).
- sort alphabetically

v5: Actually try to sort them, and while at it, sort all the ones I
touch.

v6: Rebase onto i915 changes.

v7: Rebase once more.

drm: bridge: Constify mode arguments to bridge .mode_set() operation

2019-01-14T01:51:14+00:00

The mode and ajusted_mode passed to the bridge .mode_set() operation
should never be modified by the bridge (and are not in any of the
existing bridge drivers). Make them const to make this clear.

drm/bridge: analogix_dp: Fix misleading indentation reported by smatch

2018-10-29T13:47:39+00:00

This patch avoids that building the bridge/analogix source code with
smatch triggers complaints about inconsistent indenting. It also fixes
a typo in DRM_ERROR message, attch is replaced for attach.

drm/bridge: analogix_dp: Downgrade "Link Training" messages to dev_dbg

2018-09-13T08:47:17+00:00

The Analogix DP bridge driver is pretty verbose, and outputs
things like

[  619.414067] rockchip-dp ff970000.edp: Link Training Clock Recovery success
[  619.429233] rockchip-dp ff970000.edp: Link Training success!

each time the display gets unblanked. While it is good to know
that the device is behaving correctly, users already know that
because they can see some video output.

Let's keep these messages for cases where we need to actually
debug the driver (we have dynamic debug to enable them at runtime
if need be), and let's keep the kernel quiet otherwise.

drm: drop _mode_ from drm_mode_connector_attach_encoder

2018-07-13T16:40:27+00:00

Again to align with the usual prefix of just drm_connector_. Again
done with sed + manual fixup for indent issues.

Just makes it longer, and for most things in drm_connector.[hc] we
just use the drm_connector_ prefix. Done with sed + a bit of manual
fixup for the indenting.

drm/bridge: analogix_dp: Split the platform-specific poweron in two parts

2018-04-24T06:34:49+00:00

Some of the platform-specific stuff in rockchip_dp_poweron() needs to
happen before the generic code.  Some needs to happen after.  Let's
split the callback in two.

Specifically we can't start doing PSR work until _after_ the whole
controller is up, so don't set the enable until the end.
