1380313281 drm/core: Preserve the framebuffer after removing it.
Previously RMFB and fd close chose to disable any plane that had
an active framebuffer from this file. If it was a primary plane the
crtc was disabled. However the fbdev code or any system compositor
should restore the planes anyway so there's no need to do it twice.

The old fb_id is zero'd, so there's no danger of being able to
restore the fb from fb_id.

4dfd64862f drm: Use vblank timestamps to guesstimate how many vblanks were missed
When lacking am accurate hardware frame counter, we can fall back to
using the vblank timestamps to guesstimagte how many vblanks have
elapsed since the last time the vblank counter was updated.

Take the oppostunity to unify the vblank_disable_and_save() and
drm_handle_vblank_events() to call the same function
(drm_update_vblank_count()) to perform the vblank updates.

If the hardware/driver has an accurate frame counter use it instead of
the timestamp based guesstimate. If the hardware/driver has neither
a frame counter nor acurate vblank timestamps, we fall back to assuming
that each drm_handle_vblank_events() should increment the vblank count
by one.

3bb403bf42 drm: Stop using linedur_ns and pixeldur_ns for vblank timestamps
linedur_ns, and especially pixeldur_ns are becoming rather inaccurate
to be used for the vblank timestamp correction. With 4k@60 the pixel
duration is already below 2ns, so the amount of error due to the
truncation to nanoseconds is introducing quite a bit of error.

We can avoid such problems if we instead calculate the timestamp
delta_ns directly from the dislay timings, avoiding the use of
these intermediate truncated values.

942840371c drm/fbdev: Update legacy plane->fb refcounting for atomic restore
Starting with commit

        commit 28cc504e8d
        Author: Rob Clark <robdclark@gmail.com>
        Date:   Tue Aug 25 15:36:00 2015 -0400

            drm/i915: enable atomic fb-helper

I've been seeing some panics on i915 when the DRM master shuts down that appear
to be caused by using an already-freed framebuffer (i.e., we're unexpectedly
dropping our initial FB's reference count to 0 and freeing it, which causes a
crash when we try to restore it later).  Digging deeper, the state FB
refcounting is working as expected, but we seem to be missing proper
refcounting on the legacy plane->fb pointers in the new atomic fbdev code.

Tracking plane->old_fb and then doing a ref/unref at the end of the
fbdev restore like we do in the legacy ioctl's ensures we don't miscount
references on plane->fb and avoids the panics.

v2 from Daniel:

Really do what the atomic ioctl does:
- Also update plane->fb and plane->crtc.
- Clear out plane->old_fb on failures too.

v3: git add everything. Oops.

v4: Also clear old_fb in all other failure paths, spotted by David.

f881bab038 gpio: keep the GPIO line names internal
This refactors the changes to the GPIO line naming mechanism to
not have so widespread effects, instead we conclude the patch series
by having created a name attribute in the GPIO descriptor, that need
not be globally unique, and it will be initialized from the old
.names array in struct gpio_chip if it exists, then used in the legacy
sysfs code like the array was used previously.

The associated changes to name lines from the device tree are
controversial and need to stand alone from this. Resulting changes:

1. Remove the export and the header for the gpio_name_to_desc() as so
far the only use is inside gpiolib.c. Staticize gpio_name_to_desc()
and move it above the only function using it.

2. Only print a warning if there are two GPIO lines with the same name.
The reason is to preserve current behaviour: before the previous
changes to the naming mechanism this would not reject probing the
driver, instead the error would occur when trying to export the line
in sysfs, so restore this behaviour, but print a friendly warning
if names collide.

c0017ed719 gpio: Introduce gpio descriptor 'name'
The latest gpio hogging mechanism assigns each gpio a 'line-name' in the
devicetree. The 'name' field is different from the 'label' field.
'label' is only used for requested GPIOs to describe its current use by
driver or userspace.

The 'name' field describes the GPIO itself, not the use. This is most
likely identical to the label in the schematic on the GPIO line and
should help to find this particular GPIO.

This is equivalent to the gpiochip->names array. However names should be
stored in the GPIO descriptor. We will use gpiochip->names in the future
only as initializer for the GPIO descriptors for drivers that assign
GPIO names hardcoded. All other GPIO names will be parsed from DT and
directly assigned to the GPIO descriptor.

This patch adds a helper function to find gpio descriptors by name
instead of gpio number.

rx_lock spinlock is only used in hci_uart_tty_receive() which is the

hci_uart_tty_receive() is protected from re-entrance by its only
caller (flush_to_ldisc() in drivers/tty/tty_buffer.c) which held a
mutex (buf->lock) for this section.
This lock allows "safe use of the line discipline's receive_buf()
method by excluding the buffer work and any pending flush from using
the flip buffer." (comments from tty_buffer_lock_exclusive() in
drivers/tty/tty_buffer.c)

So, no need to double protect this resource with rx_lock.

23aa4db78a tridentfb: Fix set_lwidth on TGUI9440 and CYBER9320
According to X.Org driver, chips older than TGUI9660 have only 1 width bit
in AddColReg. Touching the 2nd one causes I2C/DDC to fail on TGUI9440.

Set only 1 bit of width in AddColReg on TGUI9440 and CYBER9320.

7f2ea957c1 tridentfb: fix hang on Blade3D with CONFIG_CC_OPTIMIZE_FOR_SIZE
When the kernel is compiled with -Os (CONFIG_CC_OPTIMIZE_FOR_SIZE), tridentfb
hangs the machine upon load with Blade3D cards unless acceleration is disabled.

This is caused by memcpy() which copies data byte-by-byte (rep movsb) when
compiled with -Os. The card does not like that - it requires 32-bit access.

Use iowrite_32() instead.

The ssd1307fb driver supports a lot of chips from the ssd130xfb series.
This patch adds the ssd1309 chip, a 128x64 OLED driver chip. It is very

8a9d4626db OMAPDSS: hdmi: Reconfigure and restart audio when display is enabled
Reconfigure and restart audio when display is enabled, if audio
playback was active before. This is needed in a situation when an
audio+video stream application opens the audio stream before the
video. When video stream is opened the display mode may change and
that aborts audio playback, because the display is momentarily
turned off.

The audio configuration is stored when it is successfully applied and
a boolean is set when the audio playback is started and unset when
stopped. This data is used to reconfigure the audio when display is
re-enabled. The audio playback is aborted if the reconfiguration fails.

A new spin lock is introduced in order to protect state variables
related to audio playback status. This is needed for the transition
from display enabled state (when audio start/stop commands can be
written to HW) to display disabled state (when audio start/stop
commands update only the hdmi.audio_playing variable) to always
serialize correctly with the start/stop audio commands. The already
existing mutex can not be used, because the audio start and stop
commands are executed in atomic context.

For example: when display is turned back on we take the spinlock and
we can be sure that the audio start/stop status will not change while
we update the HW according to hdmi.audio_playing state and set
hdmi.display_enabled to true. After releasing the lock
hdmi.display_enabled is true and all audio_start and audio_stop
commands write their stuff directly to HW.

30c64664f1 drm: Allow also control clients to check the drm version
This should be harmless.
Vmware will, due to old infrastructure reasons, be using a privileged
control client to supply GUI layout information rather than obtaining
it from the device. That control client will be needing access to DRM
version information.

9de7605ea2 ixgbe: Correct several flaws with with DCA setup
This change does two things. First, it makes it so that we always
set the relaxed ordering bits related to the DCA registers even if
DCA is not enabled. Second, it moves the configuration out of the
ixgbe_down function and into the ixgbe_configure function before
enabling the Rx and Tx rings. This ensures that DCA is configured
correctly before starting to process packets.

Thanks to Alex Duyck for this fix.
