We've got a regression report that 4.1-rc causes noises on a Dell
laptop. Similar like Realtek codec, this seems also triggered by the
recent power_save_node feature. As this kind of issue is quite hard
to debug without actual hardware, disable the power_save_node flag for
this codec as a workaround.

A new AMD controller [1002:aac8] seems to need the quirk for other AMD
NS HDMI stuff, otherwise it gives noisy sounds.

This allows user to test power_save_node feature via sysfs or patch

This reverts commit 7290006d8c.
Through the regression report, it was revealed that the
tpacpi_led_set() call to thinkpad_acpi helper doesn't only toggle the
mute LED but actually mutes the sound. This is contradiction to the
expectation, and rather confuses user.
According to Henrique, it's not trivial to judge which TP model
behaves "LED-only" and which model does whatever more intrusive, as
Lenovo's implementations vary model by model. So, from the safety
reason, we should revert the patch for now.

We've got reports that ALC3226 (a Dell variant of ALC292) gives click
noises at transition from D3 to D0 when the widget power-saving is
enabled. Further debugging session showed that avoiding it isn't
trivial, unfortunately, since paths are basically activated
dynamically while the pins have been already enabled.
This patch disables the widget power-saving for such codecs.
Reported-by: Jonathan McDowell <noodles@earth.li>
Signed-off-by: Takashi Iwai <tiwai@suse.de>
The widget (node) power-saves restore the widget states at each
transition from D3 to D0 on each node. This was added in the commit
[d545a57c5f84:ALSA: hda - Sync node attributes at resume from widget
power saving]. However, the test was rater false-positive; this
wasn't needed for any codecs.
Since the resync may take significant number of additional verbs to be
executed, it's better to reduce it. Let's disable it for now again.

Currently in snd_pcm_update_hw_ptr0 during interrupt,
we consider there were double acknowledged interrupts when:
1. HW reported pointer is smaller than expected, and
2. Time from last update time (hdelta) is over half a buffer time.
However, when HW reported pointer is only a few bytes smaller than
expected, and when hdelta is just a little larger than half a buffer time
(e.g. ping-pong buffer), it wrongly treats this IRQ as double acknowledged.
The condition #2 uses jiffies, but jiffies is not high resolution
since it is integer. We should consider jiffies inaccuracy.

Since commit 844b03f277 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.
An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.
Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

The Marvell mwifiex driver prevents the system to enter into a suspend
state if the card power is not preserved during a suspend/resume cycle.
So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow.
Add the keep-power-in-suspend Power Management property to the SDIO/MMC
node so the mwifiex suspend handler doesn't fail and the system is able
to enter into a suspend state.

Commit ea08de16eb ("ARM: dts: Add DISP1 power domain for exynos5420")
added a device node for the Exynos5420 DISP1 power domain but dit not
make the DP controller a consumer of that power domain.
This causes an "Unhandled fault: imprecise external abort" error if the
exynos-dp driver tries to access the DP controller registers and the PD
was turned off. This lead to a kernel panic and a complete system hang.
Make the DP controller device node a consumer of the DISP1 power domain
to ensure that the PD is turned on when the exynos-dp driver is probed.

Tegra would not only need a hardware vblank counter that
increments at leading edge of vblank, but also support
for instantaneous high precision vblank timestamp queries, ie.
a proper implementation of dev->driver->get_vblank_timestamp().
Without these, there can be off-by-one errors during vblank
disable/enable if the scanout is inside vblank at en/disable
time, and additionally clients will never see any useable
vblank timestamps when querying via drmWaitVblank ioctl. This
would negatively affect swap scheduling under X11 and Wayland.
