The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @haskernel@ @@ @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // </smpl> Signed-off-by:

This driver sure needs some rework. For now, let's try to clean it up a bit before start reimplementing anything. checkpatch.pl still not happy with this driver after this patch, but the most annoying errors are gone, comments now use C-style only, labels are well placed and some other minor fixes. Some more clean up patches will come as I work on this driver. Please review it carefully.

This driver is for VERY old i2c-over-parallel port teletext receiver boxes. Rather then spending effort on converting this driver to V4L2, and since it is extremely unlikely that anyone still uses one of these devices, it was decided to drop it (after discussing this as well with the original author, Phil Blundell).

Old driver for the dpc7146 demonstration board that is no longer relevant. The last time this was tested on actual hardware was probably around 2002. Since this is a driver for a demonstration board the decision was made (after discussing this with the original author, Michael Hunold) to remove it rather than spending a lot of effort continually updating this driver to stay in sync with the latest internal V4L2 or I2C API.

Add support for Magic-Pro DMB-TH usb stick. DMB-TH is the HDTV broadcast standard used in Hong Kong and China. [...] I've also attached a second patch against the dvb-apps repository which adds a DMB-TH scan file for Hong Kong. Since the ProHDTV stick contains a DMB-TH decoder (lgs8gl5) onboard, it outputs MPEG-TS to the PC. Signed-off-by:

Add support for revision 2 of the DViCO FusionHDTV DVB-T Dual Digital 4 which has new tuners and demodulators (2 x DIB7070p). With this patch both DVB reception and IR works. The dib7000p driver currently hardwires the output mode to OUTMODE_MPEG2_SERIAL regardless of what we ask for. Modify it to allow OUTMODE_MPEG2_PAR_GATED_CLK to be set. Longer term we should remove the check completely and set the output mode correctly in all the callers. Add Kconfig bits to ensure the dib7000p and dib0070 modules are enabled. It would be nice to only do this for the !DVB_FE_CUSTOMISE case, but this is what the other DIB7070 module does (there are a number of module dependencies in the attach code). Signed-off-by:

v4l2_ctrl_query_menu_valid_items() makes it easy to handle control menus that have a lot of invalid 'holes'. For example, many MPEG encoders only support a limited subset of audio bitrates. In that case a driver can specify an array listing the set of valid bitrates and pass that to this function. Signed-off-by:

This patch adds the capability of decoding NEC protocol, received via GPIO18 line. This GPIO port can trigger saa7134 IRQ. A future improvement would be to make it a little more generic to work also with GPIO16 line. A pure IRQ code didn't work, since some delays were introduced on the tests we did. A possible approach would be to use polling at a rate of 2.5 ms or less. If a new code were taken, a code similar to nec_task() could be used. However, this would add an extra overhead to kernel, and will consume more power. Due to that, we took an hybrid approach: an IRQ upper half to trigger when a new key is received and a bottom half to convert pulse-distance into a keycode. The bottom half is polling based, to improve performance. During the bottom half proccess, GPIO18 IRQ line is disabled, preventing IRQ reentrancy and improving performance a little bit.

The BKL is now moved from the video_open function in v4l2-dev.c to the various drivers. It seems about a third of the drivers already has a lock of some sort protecting the open(), another third uses video_exclusive_open (yuck!) and the last third required adding the BKL in their open function.
