49e58a932f orinoco_cs: be more careful when matching cards with ID 0x0156:0x0002
Without CONFIG_HERMES_PRISM, only match cards that have "Version 01.01"
as the third product ID.  Those have Agere firmware.

With CONFIG_HERMES_PRISM, match all 0x0156:0x0002 cards.

0a1013c76b hostap_cs: support cards with "Version 01.02" as third product ID
Cards with numeric ID 0x0156:0x0002 and third ID "Version 01.02" can be
assumed to have Intersil firmware.  Cards with Agere firmware use
"Version 01.01".

14b9f27886 pcmcia: add PCMCIA_DEVICE_MANF_CARD_PROD_ID3
This is needed to match wireless cards with Intersil firmware that have
ID 0x0156:0x0002 and the third ID "Version 01.02".  Such cards are
currently matched by orinoco_cs, which doesn't support WPA.  They should
be matched by hostap_cs.

The first and the second product ID vary widely, so there are few users
with some particular IDs.  Of those, very few can submit a patch for
hostap_cs or write a useful bugreport.  It's still important to support
their hardware properly.

With PCMCIA_DEVICE_MANF_CARD_PROD_ID3, it should be possible to cover
the remaining Intersil based designs that kept the numeric ID and the
"version" of the reference design.

d12c51d829 ALSA: hdspm - Fix reported external sample rate on RME MADI and MADIface
In slave mode, the card can only detect the base frequency (32..48kHz)
on the MADI link (exception: 96k frames), so the real external sample
rate is this base frequency multiplied by 1, 2 or 4 depending on the
speed mode.

This patch enables 64..192kHz sample rates in clock slave mode, which
failed before due to an alleged sample rate mismatch between the MADI
link (e.g., 48kHz) and the application in DS/QS mode (e.g., 96kHz,
192kHz).

b2987a5e05 eCryptfs: Unlock keys needed by ecryptfsd
Fixes a regression caused by b5695d0463

Kernel keyring keys containing eCryptfs authentication tokens should not
be write locked when calling out to ecryptfsd to wrap and unwrap file
encryption keys. The eCryptfs kernel code can not hold the key's write
lock because ecryptfsd needs to request the key after receiving such a
request from the kernel.

Without this fix, all file opens and creates will timeout and fail when
using the eCryptfs PKI infrastructure. This is not an issue when using
passphrase-based mount keys, which is the most widely deployed eCryptfs
configuration.

9c1ed8941d hwmon: (pmbus) Add support for virtual pages
Some PMBus chips have non-standard sensor registers. An easy way to
support such sensors is to introduce virtual pages and map the non-standard
registers into standard registers on an extra page.

For this to work, the code verifying if the configured number of pages exists
has to be removed. Since a wrong number of pages can only be configured in a
front-end driver, this should not have a practical impact since the resulting
errors should be found during development and testing.

Also, functions to read the chip status while checking if a command register
exists must be modified to no longer set the page register before reading the
status, since the physical page associated with the checked register may not
exist. This does not make a functional difference since the page was already set
when the attempt to read the register was made.

2704cf5fbd drm/i915: flush plane control changes on ILK+ as well
After writing to the plane control reg we need to write to the surface
reg to trigger the double buffered register latch.  On previous
chipsets, writing to DSPADDR was enough, but on ILK+ DSPSURF is the reg
that triggers the double buffer latch.

v2: write DSPADDR too to cover pre-965 chipsets
v3: use flush_display_plane instead, that's what it's for
v4: send the right patch

3bcf603f6d drm/i915: apply timing generator bug workaround on CPT and PPT
On CougarPoint and PantherPoint PCH chips, the timing generator may fail
to start after DP training completes.  This is due to a bug in the
FDI autotraining detect logic (which will stall the timing generator and
re-enable it once training completes), so disable it to avoid silent DP
mode setting failures.

120eced9ef drm/i915: Set crtc DPMS mode to ON in intel_crtc_mode_set
This corrects the DPMS mode tracking so that the DPMS code will

d2b996ac69 Revert and fix "drm/i915/dp: remove DPMS mode tracking from DP"
This reverts commit 885a50147f.

We actually *do* need to track DPMS state so that on hotplug, we don't
retrain the link until DPMS is disabled.

However, that code had avery small bug -- it wouldn't set the
dpms_mode at mode set time, and so link retraining would not actually
occur on monitor hotplug until the monitor had gone through a DPMS
off/DPMS on cycle.

f0575e9297 drm/i915: DP_PIPE_ENABLED must check transcoder on CPT
Display port pipe selection on CPT is not done with a bit in the
output register, rather it is controlled by a couple of bits in the
separate transcoder register which indicate which display port output
is connected to the transcoder.

This patch replaces the simplistic macro DP_PIPE_ENABLED with the
rather more complicated function dp_pipe_enabled which checks the
output register to see if that is enabled, and then goes on to either
check the output register pipe selection bit (on non-CPT) or the
transcoder DP selection bits (on CPT).

Before this patch, any time the mode of pipe A was changed, any
display port outputs on pipe B would get disabled as
intel_disable_pch_ports would ensure that the mode setting operation
could occur on pipe A without interference from other outputs
connected to that pch port

59f3e272d7 drm/i915: In intel_dp_init, replace read of DPCD with intel_dp_get_dpcd
Eliminates an open-coded read and also gains the retry behaviour of
intel_dp_get_dpcd, which seems like a good idea.

92fd8fd13b drm/i915: Use dp_detect_common in hotplug helper function
This uses the common dpcd reading routine, i915_dp_detect_common,
instead of open-coding a call to intel_dp_aux_native_read. Besides
reducing duplicated code, this also gains the read retries which
may be necessary when a cable is first plugged back in and the link
needs to be retrained.
