From f0c0529ed1e44dcd7af12d6fcdda92d6eb424128 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sat, 28 Jun 2008 05:57:06 -0300 Subject: Add support for em2860 based PointNix Intra-Oral Camera From: Devin Heitmueller em28xx-cards.c em28xx-input.c em28xx-video.c em28xx.h - Add support for the PointNix Intra-Oral Camera, which required addition of a construct for reading the "snapshot" button (provided on the em2860 and em2880 chips, but this is the first case where I have seen it actually used in a product). The button is wired to pin 56 on the em2880. http://www.pointnix.com/ENG/dental/product_02.asp Thanks to Roberto Mantovani for testing the changes Signed-off-by: Devin Heitmueller Signed-off-by: Mauro Carvalho Chehab --- linux/Documentation/video4linux/CARDLIST.em28xx | 1 + linux/drivers/media/video/em28xx/em28xx-cards.c | 18 ++++ linux/drivers/media/video/em28xx/em28xx-input.c | 107 ++++++++++++++++++++++++ linux/drivers/media/video/em28xx/em28xx-video.c | 2 + linux/drivers/media/video/em28xx/em28xx.h | 14 ++++ 5 files changed, 142 insertions(+) diff --git a/linux/Documentation/video4linux/CARDLIST.em28xx b/linux/Documentation/video4linux/CARDLIST.em28xx index c7e23942c..10591467e 100644 --- a/linux/Documentation/video4linux/CARDLIST.em28xx +++ b/linux/Documentation/video4linux/CARDLIST.em28xx @@ -17,3 +17,4 @@ 16 -> Hauppauge WinTV HVR 950 (em2880) [2040:6513,2040:6517,2040:651b,2040:651f] 17 -> Pinnacle PCTV HD Pro Stick (em2880) [2304:0227] 18 -> Hauppauge WinTV HVR 900 (R2) (em2880) [2040:6502] + 19 -> PointNix Intra-Oral Camera (em2860) diff --git a/linux/drivers/media/video/em28xx/em28xx-cards.c b/linux/drivers/media/video/em28xx/em28xx-cards.c index df0004b1e..871d81242 100644 --- a/linux/drivers/media/video/em28xx/em28xx-cards.c +++ b/linux/drivers/media/video/em28xx/em28xx-cards.c @@ -427,6 +427,19 @@ struct em28xx_board em28xx_boards[] = { .amux = EM28XX_AMUX_LINE_IN, } }, }, + [EM2860_BOARD_POINTNIX_INTRAORAL_CAMERA] = { + .name = "PointNix Intra-Oral Camera", + .has_snapshot_button = 1, + .vchannels = 1, + .tda9887_conf = TDA9887_PRESENT, + .tuner_type = TUNER_ABSENT, + .decoder = EM28XX_SAA7113, + .input = { { + .type = EM28XX_VMUX_SVIDEO, + .vmux = SAA7115_SVIDEO3, + .amux = 0, + } }, + }, };

If you stick strictly to rule (c), you should ask the submitter to rediff, but this is a totally counter-productive waste of time and energy. Rule (b) allows you to adjust the code, but then it is very impolite to change one submitter's code and make him endorse your bugs. To solve this problem, it is recommended that you add a line between the last Signed-off-by header and yours, indicating the nature of your changes. While there is nothing mandatory about this, it seems like prepending the description with your mail and/or name, all enclosed in square brackets, is noticeable enough to make it obvious that you are responsible for last-minute changes. Example : Signed-off-by: Random J Developer [lucky@maintainer.example.org: struct foo moved from foo.c to foo.h] Signed-off-by: Lucky K Maintainer This practise is particularly helpful if you maintain a stable branch and want at the same time to credit the author, track changes, merge the fix, and protect the submitter from complaints. Note that under no circumstances can you change the author's identity (the From header), as it is the one which appears in the changelog." This patch adds a quick description at this rule under README.patches. This is particularly important when merging mercurial tree with -git one.
