35962eaef4 Merge tag 'drm-atmel-hlcdc-fixes/for-4.7-rc2' of github.com:bbrezillon/linux-at91 into drm-fixes
Two trivial bugfixes for the atmel-hlcdc driver.

The first one is making use of __drm_atomic_helper_crtc_destroy_state()
instead of duplicating its logic in atmel_hlcdc_crtc_reset() and
risking memory leaks if other objects are added to the common CRTC
state.

The second one is fixing a possible NULL pointer dereference.

Harden the plane_check() code to drop attempts at scaling because
that is not supported. Make hdlcd_plane_atomic_update() set the pitch
and line length registers that correctly reflect the plane's values.
And make hdlcd_crtc_mode_set_nofb() a helper function for
hdlcd_crtc_enable() rather than an exposed hook.

a95acec16d drm: hdlcd: Revamp runtime power management
Because the HDLCD driver acts as a component master it can end
up enabling the runtime PM functionality before the encoders
are initialised. This can cause crashes if the component slave
never probes (missing module) or if the PM operations kick in
before the probe finishes.

Move the enabling of the runtime PM after the component master
has finished collecting the slave components and use the DRM
atomic helpers to suspend and resume the device.

afee4d8707 Revert "drm/i915: Avoid stalling on pending flips for legacy cursor updates"

"drm/i915: Allow nonblocking update of pageflips" should have been
split up, misses a proper commit message and seems to cause issues in
the legacy page_flip path as demonstrated by kms_flip.

"drm/i915: Make unpin async" doesn't handle the unthrottled cursor
updates correctly, leading to an apparent pin count leak. This is
caught by the WARN_ON in i915_gem_object_do_pin which screams if we
have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins.

Unfortuantely we can't just revert these two because this patch series
came with a built-in bisect breakage in the form of temporarily
removing the unthrottled cursor update hack for legacy cursor ioctl.
Therefore there's no other option than to revert the entire pile :(

There's one tiny conflict in intel_drv.h due to other patches, nothing
serious.

Normally I'd wait a bit longer with doing a maintainer revert, but
since the minimal set of patches we need to revert (due to the bisect
breakage) is so big, time is running out fast. And very soon
(especially after a few attempts at fixing issues) it'll be really
hard to revert things cleanly.

Lessons learned:
- Not a good idea to rush the review (done by someone fairly new to
  the area) and not make sure domain experts had a chance to read it.

- Patches should be properly split up. I only looked at the two
  patches that should be reverted in detail, but both look like the
  mix up different things in one patch.

- Patches really should have proper commit messages. Especially when
  doing more than one thing, and especially when touching critical and
  tricky core code.

- Building a patch series and r-b stamping it when it has a built-in
  bisect breakage is not a good idea.

- I also think we need to stop building up technical debt by
  postponing atomic igt testcases even longer. I think it's clear that
  there's enough corner cases in this beast that we really need to
  have the testcases _before_ the next step lands.

afe705be38 drm: Wrap direct calls to driver->gem_free_object from CMA
Since the introduction of (struct_mutex) lockless GEM bo freeing, there
are a pair of driver vfuncs for freeing the GEM bo, of which the driver
may choose to only implement driver->gem_object_free_unlocked (and so
avoid taking the struct_mutex along the free path). However, the CMA GEM
helpers were still calling driver->gem_free_object directly, now NULL,
and promptly dying on the fancy new lockless drivers. Oops.

Robert Foss bisected this to b82caafcf2 (drm/vc4: Use lockless gem BO
free callback) on his vc4 device, but that just serves as an enabler for
9f0ba539d1 (drm/gem: support BO freeing without dev->struct_mutex).

1e8985a835 drm: fix fb refcount issue with atomic modesetting
After commit 027b3f8ba9 ("drm/modes: stop
handling framebuffer special") extra fb refs are left around when doing
atomic modesetting.

The problem is that the new drm_property_change_valid_get() does not
return anything in the '**ref' parameter, which causes
drm_property_change_valid_put() to do nothing.

For some reason this doesn't cause problems with legacy API.

Also, previously the code only set the 'ref' variable for fbs, with this
patch the 'ref' is set for all objects.

b201e743f4 drm: add missing drm_mode_set_crtcinfo call
When setting mode via MODE_ID property,
drm_atomic_set_mode_prop_for_crtc() does not call
drm_mode_set_crtcinfo() which possibly causes:

"[drm:drm_calc_timestamping_constants [drm]] *ERROR* crtc 32: Can't
calculate constants, dotclock = 0!"

Whether the error is seen depends on the previous data in state->mode,
as state->mode is not cleared when setting new mode.

This patch adds drm_mode_set_crtcinfo() call to
drm_mode_convert_umode(), which is called in both legacy and atomic
paths. This should be fine as there's no reason to call
drm_mode_convert_umode() without also setting the crtc related fields.

drm_mode_set_crtcinfo() is removed from the legacy drm_mode_setcrtc() as
that is no longer needed.

This already has the advantage that for the common case when someone

Code stolen from gma500.

This is just a minor bit of safety code that I spotted and figured it
might be useful if we put it into the core. This is to make the
get_gamma ioctl reflect likely reality even before the first set_gamma
ioctl call.

v2 on irc: Extend commit message per Maarten's suggestions.

a345918d6e vga_switcheroo: Support deferred probing of audio clients
Daniel Vetter pointed out that vga_switcheroo_client_probe_defer() could
be needed by audio clients as well. To avoid mistakes when someone adds
conditions for these in the future, constrain the single existing
condition to VGA clients by checking for PCI_BASE_CLASS_DISPLAY. This
encompasses both PCI_CLASS_DISPLAY_VGA as well as PCI_CLASS_DISPLAY_3D,
which is used by some Nvidia Optimus GPUs.

Any future checks for audio clients should then be constrained to
PCI_BASE_CLASS_MULTIMEDIA.

v6: Spun out from commit introducing vga_switcheroo_client_probe_defer()
    to keep it a pure refactoring change. (Emil Velikov, Jani Nikula)

b00e5334ab vga_switcheroo: Add helper for deferred probing
So far we've got one condition when DRM drivers need to defer probing
on a dual GPU system and it's coded separately into each of the relevant
drivers. As suggested by Daniel Vetter, deduplicate that code in the
drivers and move it to a new vga_switcheroo helper. This yields better
encapsulation of concepts and lets us add further checks in a central
place. (The existing check pertains to pre-retina MacBook Pros and an
additional check is expected to be needed for retinas.)

One might be tempted to check deferred probing conditions in
vga_switcheroo_register_client(), but this is usually called fairly late
during driver load. The GPU is fully brought up and ready for switching
at that point. On boot the ->probe hook is potentially called dozens of
times until it finally succeeds, and each time we'd repeat bringup and
teardown of the GPU, lengthening boot time considerably and cluttering
logfiles. A separate helper is therefore needed which can be called
right at the beginning of the ->probe hook.

Note that amdgpu currently does not call this helper as the AMD GPUs
built into MacBook Pros are only supported by radeon so far.

v2: This helper could eventually be used by audio clients as well,
    so rephrase kerneldoc to refer to "client" instead of "GPU"
    and move the single existing check in an if block specific
    to PCI_CLASS_DISPLAY_VGA devices. Move documentation on
    that check from kerneldoc to a comment. (Daniel Vetter)

v3: Mandate in kerneldoc that registration of client shall only
    happen after calling this helper. (Daniel Vetter)

v4: Rebase on 412c8f7de0 ("drm/radeon: Return -EPROBE_DEFER when
    amdkfd not loaded")

v5: Some Optimus GPUs use PCI_CLASS_DISPLAY_3D, make sure those are
    matched as well. (Emil Velikov)

v6: The if-condition referring to PCI_BASE_CLASS_DISPLAY may be
    considered a functional change. Move to a separate commit to
    keep this a pure refactoring change. (Emil Velikov, Jani Nikula)

d0196c8d5d drm/omap: include gpio/consumer.h where needed

otherwise produce a build error:

This replaces the existing linux/gpio.h with linux/gpio/consumer.h
where needed. In case of panel-lgphilips-lb035q02.c however, we
also have to include linux/gpio.h to get the definition of gpio_is_valid
and gpio_set_value_cansleep that are used for the non-DT case.

If DRM_OMAP does not select OMAP2_DSS it is possible to build a kernel with

Also, regulator_set_voltage() is misused in the driver, as it is

be changed dynamically at runtime. In DSS's case, we always want a fixed
voltage, set in the .dts files.

91cd220aad drm/omap: fix OMAP4 hdmi_core_powerdown_disable()
hdmi_core_powerdown_disable() is supposed to disable HDMI core's
power-down mode. However, the function sets the power-down bit to 0,
which means "enable power-down".

This hasn't caused any issues as the PD seems to affect only interrupts
from HDMI core, and none of those interrupts are used at the moment. CEC
functionality requires core interrupts, and the PD mode needs to be
fixed.

This patch fixes hdmi_core_powerdown_disable() to actually disable the
PD mode.
