2008-04-25phylib: Add support for board-level PHY fixupsAndy Fleming
Sometimes the specific interaction between the platform and the PHY requires special handling. For instance, to change where the PHY's clock input is, or to add a delay to account for latency issues in the data path. We add a mechanism for registering a callback with the PHY Lib to be called on matching PHYs when they are brought up, or reset.

2008-04-24V4L/DVB (7651): tuner-xc2028: Several fixes to SCODEMauro Carvalho Chehab
This patch fixes several issues on SCODE: 1) The extracting tool weren't generating the proper tags for SCODE. This has almost no effect, since those tags shouldn't be used; 2) DIBCOM52 were using a wrong IF. It should be 5200, instead of 5700; 3) seek_firmware were wanting an exact match for firmware type. This is wrong. As result, no SCODE firmware were loaded; 4) A few files were including the wrong file for seeking demod firmwares; 5) XC3028_FE_DEFAULT can be used, if user doesn't want to load a firmware. However, this weren't documentated. This feature require more testing. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

2008-04-24V4L/DVB (7448): Add support for Kworld ATSC 120Mauro Carvalho Chehab
This board has a s5h1409 demod, plus a xc30x8 tuner (probably, xc3018). This patch adds proper support for radio, video, s-video, composite and ATSC. However, support for radio and video depends on having s5h1409 i2c gate open, otherwise, xc30x8 chip won't be visible. For a better support, some rework is needed on cx88 driver, to allow adding xc30x8 to i2c bus without sending i2c 0 byte reading to 0xc2 address. Thanks to Vanessa Ezekowitz <vanessaezekowitz@gmail.com> for helping to figure out the proper parameters for s5h1409 and the GPIO pins used by each configuration.

The card has sixteen (16) BNC video inputs, four of them on the board itself and twelve on three daughter-cards. It has a single bt878 chip, no tuner and what looks like and audio input. After doing some research I managed to get only eight channels working by forcing card=125 and those DID NOT match channels 0-7 on the card, and no audio. Based on what was working for card=125, I added the card definition block, added a specific muxsel routine and got the card working fully with xawtv, where the sixteen channels show up as Composite0 to Composite15, matching the channel labels in the card and daughter-cards. I have made no efforts yet to get audio working, but would appreciate any pointers. Signed-off-by: Ernesto Hernández-Novich <emhn@usb.ve> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

This patch moves saa7134_tuner_callback to saa7134-cards, originally used only by tda8290 DVB-S boards. The callback was made more generic to support other tuners.

This adds support for Quanta IL1 mini-notebook to alsa, defining a new model for it. It comes with an ALC267 codec chip. Some notes about this model: * In headphone automute, I use AC_VERB_SET_PIN_WIDGET_CONTROL instead of common amp mute, to avoid conflict with mixer switch (mixer and automute use the same nid). * The only connected capture sources in the hardware are the internal mic and external mic jack. So instead of using an input source selector like on other ALC268 models, the mic automute automatically switch between captures.

[mszeredi@suse.cz] rewrite and split big patch into managable chunks /proc/mounts in its current form lacks important information: - propagation state - root of mount for bind mounts - the st_dev value used within the filesystem - identifier for each mount and it's parent It also suffers from the following problems: - not easily extendable - ambiguity of mountpoints within a chrooted environment - doesn't distinguish between filesystem dependent and independent options - doesn't distinguish between per mount and per super block options This patch introduces /proc/<pid>/mountinfo which attempts to address all these deficiencies. Code shared between /proc/<pid>/mounts and /proc/<pid>/mountinfo is extracted into separate functions. Thanks to Al Viro for the help in getting the design right.
