Add a blob property tracking the current mode to the CRTC state, and
ensure it is properly updated and referenced.
v2: Continue using crtc_state->mode inside getcrtc, instead of reading
out the mode blob. Use IS_ERR and PTR_ERR from create_blob. Move
set_mode_prop_for_crtc to later patch where it actually gets used.
Enforce !!state->enable == !!state->mode_blob inside
drm_atomic_crtc_check.

Add a new helper, to be used later for blob property management, that
sets the mode for a CRTC state, as well as updating the CRTC enable/active
state at the same time.
v2: Do not touch active/mode_changed in CRTC state. Document return
value. Remove stray drm_atomic_set_mode_prop_for_crtc declaration.
v3: Remove i915 changes, and leave it directly bashing crtc_state->mode
for the meantime.

Add an ioctl which allows users to create blob properties from supplied
data. Currently this only supports modes, creating a drm_display_mode from
the userspace drm_mode_modeinfo.
v2: Removed size/type checks.
Rebased on new patches to allow error propagation from create_blob,
as well as avoiding double-allocation.

Allow drm_bridge objects to link to each other in order to form an encoder
chain. The requirement for creating a chain of bridges comes because the
MSM drm driver uses up its encoder and bridge objects for blocks within
the SoC itself. There isn't anything left to use if the SoC display output
is connected to an external encoder IC. Having an additional bridge
connected to the existing bridge helps here. In general, it is possible for
platforms to have multiple devices between the encoder and the
connector/panel that require some sort of configuration.
We create drm bridge helper functions corresponding to each op in
'drm_bridge_funcs'. These helpers call the corresponding
'drm_bridge_funcs' op for the entire chain of bridges. These helpers are
used internally by drm_atomic_helper.c and drm_crtc_helper.c.
The drm_bridge_enable/pre_enable helpers execute enable/pre_enable ops of
the bridge closet to the encoder, and proceed until the last bridge in the
chain is enabled. The same holds for drm_bridge_mode_set/mode_fixup
helpers. The drm_bridge_disable/post_disable helpers disable the last
bridge in the chain first, and proceed until the first bridge in the chain
is disabled.
drm_bridge_attach() remains the same. As before, the driver calling this
function should make sure it has set the links correctly. The order in
which the bridges are connected to each other determines the order in which
the calls are made. One requirement is that every bridge in the chain
should point the parent encoder object. This is required since bridge
drivers expect a valid encoder pointer in drm_bridge. For example, consider
a chain where an encoder's output is connected to bridge1, and bridge1's
output is connected to bridge2:
/* Like before, attach bridge to an encoder */
bridge1->encoder = encoder;
ret = drm_bridge_attach(dev, bridge1);
..
/*
* set the first bridge's 'next' bridge to bridge2, set its encoder
* as bridge1's encoder
*/
bridge1->next = bridge2
bridge2->encoder = bridge1->encoder;
ret = drm_bridge_attach(dev, bridge2);
...
...
This method of bridge chaining isn't intrusive and existing drivers that
use drm_bridge will behave the same way as before. The bridge helpers also
cleans up the atomic and crtc helper files a bit.

drm_atomic_helper_commit_planes calls all atomic_begin's first,
then updates all planes, finally calling atomic_flush.
Some drivers may want to things like disabling irq's
from their atomic_begin, in which case a second call to atomic_begin
will splat. By using commit_planes_on_crtc on each crtc in the
atomic state they'll evade that issue.

Scattering of random drm core patches. Bunch of atomic prep work too, but
the final bits for blob properties, atomic modesets and lifting the
experimental tag on the atomic ioctl are still blocked on Daniel Stone
finalizing and testing the weston support for it. I hope that we can get
it all ready for 4.2 though.

Drivers may need to store the state of shared resources, such as PLLs
or FIFO space, into the atomic state. Allow this by making it possible
to subclass drm_atomic_state.
Changes since v1:
- Change member names for functions to atomic_state_(alloc,clear)
- Change __drm_atomic_state_new to drm_atomic_state_init
- Allow free function to be overridden too, in case extra memory is
allocated in alloc.
Changes since v2:
- Rename *_default_free to default_release, to make clear it doesn't
free the state object itself.

Displayport compliance test 4.2.2.6 requires that a source device be capable of
detecting a corrupt EDID. The test specification states that the sink device
sets up the EDID with an invalid checksum. To do this, the sink sets up an
invalid EDID header, expecting the source device to generate the checksum and
compare it to the value stored in the last byte of the block data.
Unfortunately, the DRM EDID reading and parsing functions are actually too good
in this case; the header is fixed before the checksum is computed and thus the
test never sees the invalid checksum. This results in a failure to pass the
compliance test.
To correct this issue, when the EDID code detects that the header is invalid,
a flag is set to indicate that the EDID is corrupted. In this case, it sets
edid_corrupt flag and continues with its fix-up code. This flag is also set in
the case of a more seriously damaged header (fixup score less than the
threshold). For consistency, the edid_corrupt flag is also set when the
checksum is invalid as well.
V2:
- Removed the static bool global
- Added a bool to the drm_connector struct to reaplce the static one for
holding the status of raw edid header corruption detection
- Modified the function signature of the is_valid function to take an
additional parameter to store the corruption detected value
- Fixed the other callers of the above is_valid function
V3:
- Updated the commit message to be more clear about what and why this
patch does what it does.
- Added comment in code to clarify the operations there
- Removed compliance variable and check_link_status update; those
have been moved to a later patch
- Removed variable assignment from the bottom of the test handler
V4:
- Removed i915 tag from subject line as the patch is not i915-specific
V5:
- Moved code causing a compilation error to this patch where the variable
is actually declared
- Maintained blank lines / spacing so as to not contaminate the patch
V6:
- Removed extra debug messages
- Added documentation to for the added parameter on drm_edid_block_valid
- Fixed more whitespace issues in check_link_status
- Added a clear of the header_corrupt flag to the end of the test handler
in intel_dp.c
- Changed the usage of the new function prototype in several places to use
NULL where it is not needed by compliance testing
V7:
- Updated to account for long_pulse flag propagation
V8:
- Removed clearing of header_corrupt flag from the test handler in intel_dp.c
- Added clearing of header_corrupt flag in the drm_edid_block_valid function
V9:
- Renamed header_corrupt flag to edid_corrupt to more accurately reflect its
value and purpose
- Updated commit message
V10:
- Updated for versioning and patch swizzle
- Revised the title to more accurately reflect the nature and contents of
the patch
- Fixed formatting/whitespace problems
- Added set flag when computed checksum is invalid

The magic auth tokens we have are a simple map from cyclic IDs to drm_file
objects. Remove all the old bulk of code and replace it with a simple,
direct IDR.
The previous behavior is kept. Especially calling authmagic multiple times
on the same magic results in EINVAL except on the first call. The only
difference in behavior is that we never allocate IDs multiple times as
long as a client has its FD open.
v2:
- Fix return code of GetMagic()
- Use non-cyclic IDR allocator
- fix off-by-one in "magic > INT_MAX" sanity check
v3:
- drop redundant "magic > INT_MAX" check

This was a bit too much cargo-culted, so lets make it solid:
- vblank->count doesn't need to be an atomic, writes are always done
under the protection of dev->vblank_time_lock. Switch to an unsigned
long instead and update comments. Note that atomic_read is just a
normal read of a volatile variable, so no need to audit all the
read-side access specifically.
- The barriers for the vblank counter seqlock weren't complete: The
read-side was missing the first barrier between the counter read and
the timestamp read, it only had a barrier between the ts and the
counter read. We need both.
- Barriers weren't properly documented. Since barriers only work if
you have them on boths sides of the transaction it's prudent to
reference where the other side is. To avoid duplicating the
write-side comment 3 times extract a little store_vblank() helper.
In that helper also assert that we do indeed hold
dev->vblank_time_lock, since in some cases the lock is acquired a
few functions up in the callchain.
Spotted while reviewing a patch from Chris Wilson to add a fastpath to
the vblank_wait ioctl.
v2: Add comment to better explain how store_vblank works, suggested by
Chris.
v3: Peter noticed that as-is the 2nd smp_wmb is redundant with the
implicit barrier in the spin_unlock. But that can only be proven by
auditing all callers and my point in extracting this little helper was
to localize all the locking into just one place. Hence I think that
additional optimization is too risky.

ASoC: Updates for v4.2
The big thing this release has been Liam's addition of topology support
to the core. We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares.
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring.
- Big refactoring and cleanup serieses for the Wolfson ADSP and TI
TAS2552 drivers.
- Support for TI TAS571x power amplifiers.
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
- Support for x86 systems with RT5650 and Qualcomm Storm.

Add support for enabling codec wakeup override signal to allow
re-enumeration of the controller on SKL after resume from low power state.
In SKL, HDMI/DP codec and PCH HD Audio Controller are in different power
wells, so it's necessary to reset display audio codecs when power well on,
otherwise display audio codecs will disappear when resume from low power
state.
Reset steps when power on:
enable codec wakeup -> azx_init_chip() -> disable codec wakeup

If kref_put_mutex returns true then the caller or the put function is responsible
for unlocking the mutex. The usual pattern assumes that the free
callback unlocks the mutex, but since that is shared with the locked
variant we need to explicitly unlock here.

Because of iMX6 & Rockchip have differnet mpll config parameter,
the VLEVCTRL parameter would be different. In this case we should
separate VLEVCTRL setting from the common dw_hdmi driver, config
this parameter in platform driver(dw_hdmi-imx and dw_hdmi-rockchip)

drm/panel: Changes for v4.1-rc1
This set of changes adds support for a whole bunch of new panels, mostly
simple ones. There's now also support for panels to provide display
timings rather than fixed modes, which should allow panels to work with
a larger number of display drivers. Eventually drivers should migrate to
this new interface and the fixed modes removed from panels.
There are also a couple of sparse fixes for the PS8622 and PS8625 bridge
drivers.

Many panel data sheets, additionally to typical values, list allowed
ranges for timings such as hsync/vsync lengths, porches, and the pixel
clock rate. These can be stored in a struct display_timing, to be used
by an encoder mode_fixup callback to clamp user provided timing values
or to validate workarounds for clock source limitations.
This patch adds a new drm_panel_funcs callback that returns the panel's
available display_timing entries.

drm/tegra: Changes for v4.1-rc1
Perhaps the most noteworthy change in this set is the implementation of
a hardware VBLANK counter using host1x syncpoints. The SOR registers can
now be dumped via debugfs, which can be useful while debugging. The IOVA
address space maintained by the driver can also be dumped via debugfs.
Other than than, these changes are mostly cleanup work, such as making
register names more consistent or removing unused code (that was left
over after the atomic mode-setting conversion). There's also a fix for
eDP that makes the driver cope with firmware that already initialized
the display (such as the firmware on the Tegra-based Chromebooks).

Drivers that subclass CRTC, plane or connector state need to carefully
duplicate the code that the atomic helpers have. This is bound to cause
breakage eventually because it requires auditing all drivers and update
them when code is added to the helpers.
In order to avoid that, implement new helpers that perform the required
steps when copying and destroying state. These new helpers are exported
so that state-subclassing drivers can use them. The default helpers are
implemented using them as well, providing a single location that needs
to be changed when adding to base atomic states.

Currently DRM_IOCTL_DEF_DRV does '[DRM_IOCTL_NR(DRM_##ioctl)]' which
doesn't make much sense since DRM_##ioctl is already a the raw ioctl
number. So change it to 'DRM_IOCTL_NR(DRM_IOCTL_##ioctl) - DRM_COMMAND_BASE'
which means the DRM_IOCTL_NR() now makes sense, and also this also means
if there's a mistake in the DRM_IOCTL_##ioctl macros we might get a
warning about it (eg. we would have gotten a sparse warning about the
i915 colorkey get/set ioctl being defined to be the same thing).
