Yet a few more fixes popped up in this week.
 
 The biggest change here is the addition of pinctrl support for Atmel,
 which turned out to be almost mandatory to make things working.
 
 The rest are a few fixes for M-Audio usb-audio device and a fix for
 regression of HD-audio HDMI codecs with alsactl in the recent kernel.

Sebastian Ott 509d97b6f9 s390/chsc: fix SEI usage
cbc0dd1 "s390/pci: CHSC PCI support for error and availability events"
introduced a new SEI notification type as part of pci support.
The way SEI was called with nt2 and nt0 consecutive broke the nt0
stuff used for channel subsystem notifications.

The reason why this was broken with the mentioned patch is that you
cannot selectively disable type 0 notifications (so even when asked
for type 2 only, type 0 could be presented).

The way to do it is to tell SEI which types of notification you can
process and -this is the important part- look at the SEI result which
notification type you actually received.

Daniel Lezcano 8aef33a7cf cpuidle: remove the power_specified field in the driver
We realized that the power usage field is never filled and when it
is filled for tegra, the power_specified flag is not set causing all
of these values to be reset when the driver is initialized with
set_power_state().

However, the power_specified flag can be simply removed under the
assumption that the states are always backward sorted, which is the
case with the current code.

This change allows the menu governor select function and the
cpuidle_play_dead() to be simplified.  Moreover, the
set_power_states() function can removed as it does not make sense
any more.

Drop the power_specified flag from struct cpuidle_driver and make
the related changes as described above.

As a consequence, this also fixes the bug where on the dynamic
C-states system, the power fields are not initialized.

Fixes a bug introduced by commit c8f2f0db1 ("zram: Fix handling

during disk write. Invalid references could occur in two cases:
 - Incoming data expands on compression: In this case, reference was
made to kunmap()'ed bio page.
 - Partial (non PAGE_SIZE) write with incompressible data: In this
case, reference was made to a kfree()'ed buffer.

Hans de Goede c930812fe5 udldrmfb: Fix EDID not working with monitors with EDID extension blocks
udldrmfb only reads the main EDID block, and if that advertises extensions
the drm_edid code expects them to be present, and starts reading beyond the
buffer udldrmfb passes it.

Although it may be possible to read more EDID info with the udl we simpy don't
know how, and even if trial and error gets it working on one device, that is
no guarantee it will work on other revisions. So this patch does a simple fix
in the form of patching the EDID info to report 0 extension blocks, this
fixes udldrmfb only doing 1024x768 on monitors with EDID extension blocks.

Aleksi Torhamo 43f789792e drm/nvc0/fb: fix crash when different mutex is used to protect same list
Fixes regression introduced in commit 861d2107
"drm/nouveau/fb: merge fb/vram and port to subdev interfaces"

nv50_fb_vram_{new,del} functions were changed to use
nouveau_subdev->mutex instead of the old nouveau_mm->mutex.
nvc0_fb_vram_new still uses the nouveau_mm->mutex, but nvc0 doesn't
have its own fb_vram_del function, using nv50_fb_vram_del instead.
Because of this, on nvc0 a different mutex ends up being used to protect
additions and deletions to the same list.

This patch is a -stable candidate for 3.7.

Fixes regression introduced in commit 70790f4f
"drm/nouveau/clock: pull in the implementation from all over the place"

When code was moved from nv50_crtc_set_clock to nvc0_clock_pll_set,
the PLLs it is used for got limited to only the first two VPLLs.

nv50_crtc_set_clock was only called to change VPLLs, so it didn't
limit what it was used for in any way. Since nvc0_clock_pll_set is
used for all PLLs, it has to specify which PLLs the code is used for,
and only listed the first two VPLLs.

Since commit 5e120f6e4b "drm/nouveau/fence:
convert to exec engine, and improve channel sync" nouveau fence sync
implementation for nv17-50 and nvc0+ started to rely on state of fence buffer
left by previous sync operation. But as pinned bo's (where fence state is
stored) are not saved+restored across suspend/resume, we need to do it
manually.

nvc0+ was fixed by commit d6ba6d215a

Marcin Slusarz 92441b2263 drm/nouveau: fix blank LVDS screen regression on pre-nv50 cards
Commit 2a44e499 ("drm/nouveau/disp: introduce proper init/fini, separate
from create/destroy") started to call display init routines on pre-nv50
hardware on module load. But LVDS init code sets driver state in a way
which prevents modesetting code from operating properly.

nv04_display_init calls nv04_dfp_restore, which sets encoder->last_dpms to
NV_DPMS_CLEARED.

drm_crtc_helper_set_mode
  nv04_dfp_prepare
    nv04_lvds_dpms(DRM_MODE_DPMS_OFF)

nv04_lvds_dpms checks last_dpms mode (which is NV_DPMS_CLEARED) and wrongly
assumes it's a "powersaving mode", the new one (DRM_MODE_DPMS_OFF) is too,
so it skips calling some crucial lvds scripts.

Ben Skeggs 1a1841d300 drm/nouveau: do not forcibly power on lvds panels
This fix was put in place to fix a bug where the eDP panel on certain
laptops fails to respond over the aux channel after suspend.

It appears that on some systems (Dell M6600, with LVDS panel) there's a
very bad interaction with the eDP init table that causes the SOR to get
very confused and not drive the panel correctly, leading to bleed.

A DPMS off/on cycle is enough to bring it back, but, this will avoid the
problem by not touching the panel GPIOs at times we're not meant to.

Sathya Perla d0b9cec3e2 be2net: fix unconditionally returning IRQ_HANDLED in INTx
commit e49cc34f introduced an unconditional IRQ_HANDLED return in be_intx()
to workaround Lancer and BE2 HW issues. This is bad as it prevents the kernel
from detecting interrupt storms due to broken HW.

The BE2/Lancer HW issues are:
1) In Lancer, there is no means for the driver to detect if the interrupt
belonged to device, other than counting and notifying events.
2) In Lancer de-asserting INTx takes a while, causing the INTx irq handler
to be called multiple times till the de-assert happens.
3) In BE2, we see an occasional interrupt even when EQs are unarmed.

Issue (1) can cause the notified events to be orphaned, if NAPI was already
running.
This patch fixes this issue by scheduling NAPI only if it is not scheduled
already. Doing this also takes care of possible events_get() race that may be
caused due to issue (2) and (3). Also, IRQ_HANDLED is returned only the first
time zero events are detected.

Setting SDIS (Stream Disable Mode- bit 4 of USBMODE register) fixes the problem.

However, in current code CI13XXX_DISABLE_STREAMING flag is only set in udc mode,
so allow disabling streaming also in host mode.

Tested on a mx6qsabrelite board.

fsl-ehci probing fails on mpc5121e:

Fix it by returning appropriate version info for mpc5121, too.

Maxime Ripard eb614c8b46 USB: select USB_ARCH_HAS_EHCI for MXS
Commit 09f6ffde (USB: EHCI: fix build error by making ChipIdea host a
normal EHCI driver) introduced a dependency on USB_EHCI_HCD for the
chipidea USB host driver, that in turns depends on USB_ARCH_HAS_EHCI.

If this symbol is not set for MXS, the MXS boards are not able to use
the chipidea driver anymore.
