drm/i915/sdvo: Add hdmi connector properties after initing the connector
drm/i915: Set the required VFMUNIT clock gating disable on Ironlake.
This reverts commit 7e24cce38a because it
was never appropriate for mainline.
Do not check for init flag before starting I/O - zram module is unusable
without this fix.
The oops mentioned in the reverted commit message was actually a problem
only with the zram version as present in project's own repository where
we allocate struct zram_stats_cpu upon device initialization. OTOH, In
mainline/staging version of zram, we allocate struct stats upfront, so
this oops cannot happen in mainline version.
Checking for init_done flag in zram_make_request() results in a *no-op*
for any I/O operation since we simply always return success. This flag
is actually set when the first write occurs on a zram disk which
triggers its initialization.

This driver duplicates the same functionality found at ir-kbd-i2c.
There were a few missing key parsers that were added by the previous
patches. The only thing left on lirc_i2c driver is the IR parsing
for Asus TV-Box and Creative/VisionTek BreakOut-Box.
Those devices use pcf8574 chip for IR.
They are old video adapters with TV tuners. Their code were never
merged upstream, and they are not chipped anymore. So, it is very
unlikely that someone would have interests on porting them to the
Linux Kernel.
Due to that, let's remove lirc_i2c, as all the remaining functionality
are already mapped via ir-kbd-i2c.

lirc-i2c implements a get key logic for the Adaptec Remote

There are two Adaptec cards defined there, but AVC-2010 doesn't have a
remote controller. So, the logic at lirc_i2c seems to be for Adaptec AVC-2410.
As we'll remove lirc_i2c from kernel, move the getkey code to ivtv driver, and
use it for AVC-2410.

When SPI wake up from OFF mode, CS is in the wrong state: force it to the
inactive state.
During the system life, I monitored the CS behavior using a oscilloscope.
I also activated debug in omap2_mcspi, so I saw when driver disable the clocks
and restore context when device is not used.Each time the CS was in the correct
state. It was only when system was put suspend to ram with off-mode activated
that on resume the CS was in wrong state( ie activated).
Changelog:
* Change from v1 to v2:
- Rebase on linus/master (after 2.6.37-rc1)
- Do some clean-up and fix indentation on both patches
- Add more explanations for patch 2
* Change from v2 to v3:
- Use directly resume function of spi_master instead of using function
- from spi_device as Grant Likely pointed it out.
- Force this transition explicitly for each CS used by a device.
* Change from v3 to v4:
- Patch clean-up according to Kevin Hilman and checkpatch.
- Now force CS to be in inactive state only if it was inactive when it was
suspended.
* Change from v4 to v5:
- Rebase on linus/master (after 2.6.37-rc3)
- Collapse some lines as pointed by Grant Likely
- Fix a spelling
* Change from v5 to v6:
- Rebase on linus/master (after 2.6.37-rc7)
- Use CONFIG_SUSPEND instead of CONFIG_PM
- Didn't use legacy PM methods anymore. Instead, add a struct dev_pm_ops and
add the resume method there.
- Fix multi-line comment style
* Change from v6 to v7:

Changeset 35680ba broke several devices:
- Sony Playstation Eye (1415:2000);
- Gigaware model 25-234 (0c45:628f);
- Logitech Messenger Plus (046d:08f6).
Probably more devices were broken by this change.
What happens is that several devices don't need to save some bandwidth
for audio.
Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since
it will reduce the alt number twice, on devices with audio.
So, let's just revert the broken logic, and think on a better solution
for usb 1.1 devices with audio that can't use the maximum packetsize.

This patch adds a loopback driver to rc-core which I've found useful for
running scripted tests of different parts of rc-core without having to
fiddle with real hardware.
Basically it emulates hardware with a learning and a non-learning
receiver and two transmitters (which correspond to the two
receivers). TX data that is sent is fed back as input on the
corresponding receiver, which allows for debugging of IR decoders,
keymaps, etc.

When trying to create persistent device names for mceusb and streamzap
devices, I noticed that their respective drivers are not creating the rc
device as a child of the USB device. Rather it creates it as virtual
device. As a result, udev cannot use the USB device information to
create persistent device names for event and lirc devices associated
with the rc device. Not having persistent device names makes it more
difficult to make use of the devices in userspace as their names can
change.
Forward-ported to media_tree staging/for_v2.6.38 and tested with
both streamzap and mceusb devices:

staging/2.6.37-rc1 branch (the tutorial recommends to include it as

Several comments on the patch:
1. Both users on the official Gotview forum and support said that PCI
DVD3 is very similar to Yuan MPC718 card so the main part of code is
taken from Yuan configuration. Some users reported it to work properly.
2. Everything is being initialized correctly including analog, dvb,
radio and alsa parts. Analogue part and alsa virtual card is tested by
myself using original Gotview card.

the last time (count to zero), no data should ever be copied

assumes that feeding is stopped after stop_feed() has been
called, ie. dvb_dmx_swfilter() isn't running, and won't be called.
There is a risk that dvb_dmx_swfilter() references freed resources

Usage of templates for large structures is a bad idea, as it wastes a
lot of space. Manually initializing the few fields we need is way more
efficient.
Also set the algorithm data const, use strlcpy instead of strcpy, fix
a small race (device data must always be set before registering said
device) and properly return error on adapter registration failure.

Now, just one old bttv board uses the old RC5 raw decoding routines.
Its conversion to rc-core requires the generation of IRQ data for both
positive and negative transitions at the IRQ line. I'm not sure if
bttv driver supports it or if the transitions will be reliable enough.
So, due to the lack of hardware for testing, the better for now is to
just move the legacy routines to bttv driver, and wait for someone with
a Nebula Digi could help to port it to use also rc-core raw decoders.

stv06xx devices have only one altsetting, but the actual used
bandwidth can be programmed through a register. We were already
setting this register lower then the max packetsize of the altsetting
indicates. This patch makes the gspca-stv06xx update the usb descriptor
for the alt setting to reflect the actual packetsize in use, so that
the usb subsystem uses the correct information for scheduling usb transfers.
This patch also tries to fallback to lower speeds in case a ENOSPC error
is received when submitting urbs, but currently this is only supported
with stv06xx cams with the pb0100 sensor, as this is the only one for
which we know how to change the framerate.

There are several fields on rc_dev that drivers can benefit. Allow drivers
to pass it as a parameter to the driver.
For now, the rc_dev parameter is optional. If drivers don't pass it, create
them internally. However, the best is to create rc_dev inside the drivers,
in order to fill other fields, like open(), close(), driver_name, etc.
So, a latter patch making it mandatory and changing the caller drivers is
welcome.

This patch merges the ir_input_dev and ir_dev_props structs into a single

by the drivers are also changed to use rc_dev as the primary interface
when dealing with rc-core.
This means that the input_dev is abstracted away from the drivers which
is necessary if we ever want to support multiple input devs per rc device.
The new API is similar to what the input subsystem uses, i.e:
rc_device_alloc()
rc_device_free()
rc_device_register()
rc_device_unregister()

This patch converts the cx88 driver (for sampling hw) to use the
decoders provided by ir-core instead of the separate ones provided
by ir-functions (and gets rid of those).
The value for MO_DDS_IO had a comment saying it corresponded to
a 4kHz samplerate. That comment was unfortunately misleading. The
actual samplerate was something like 3250Hz.
The current value has been derived by analyzing the elapsed time
between interrupts for different values (knowing that each interrupt
corresponds to 32 samples).

Currently gspca supported usb-1.1 webcams for which we support the input
button through an interrupt endpoint won't stream (not enough bandwidth
error) when used through an USB-2.0 hub.
After much debugging I've found out that the cause for this is that the
ehci-sched.c schedeling code does not like it when there are already urb's
scheduled when (large) isoc urbs are queued. By moving the submission
of the interrupt urbs to after submitting the isoc urbs the camera
starts working again through usb-2.0 hubs.
Note that this does not fix isoc. streaming through a usb-hub while another
1.1 usb device (like the microphone of the same cam) is also active
at the same time :(
I've spend a long time analyzing the linux kernel ehci scheduler code,
resulting in this (long) mail:
http://www.spinics.net/lists/linux-usb/msg37982.html
The conclusion of the following mail thread is that yes there are several
issues when using usb-1.1 devices through a usb-2.0 hub, but these are not
easily fixable in the current code. Fixing this in ehci-sched.c requires
an almost full rewrite, which is not bound to happen anytime soon.
So with this patch gspca driven usb-1.1 webcams will atleast work when
connected through an usb-2.0 hub when the microphone is not used.
As an added bonus this patch avoids extra destroy/create input urb cycles
when we end up falling back to a lower speed alt setting because of bandwidth
limitations.

Linux would not connect to other router running old version Cisco IOS (12.0).
This is most likely a bug in that version of IOS, since it is fixed
in later versions. As a workaround this patch allows a module parameter
to be set to disable compressing the protocol ID.
See: https://bugzilla.vyatta.com/show_bug.cgi?id=3979
RFC 1990 allows an implementation to formulate MP fragments as if protocol
compression had been negotiated. This allows us to always send compressed
protocol IDs. But some implementations don't accept MP fragments with
compressed protocol IDs. This parameter allows us to interoperate with
them. The default value of the configurable parameter is the same as the
current behavior: protocol compression is enabled. If protocol compression
is disabled we will not send compressed protocol IDs.
This is based on an earlier patch by Bob Gilligan (using a sysctl).
Module parameter is writable to allow for enabling even if ppp
is already loaded for other uses.
