      V4L/DVB (12742): em28xx: add raw VBI support for NTSC · 28abf083
      由 Devin Heitmueller 提交于 
      Add support for raw VBI capture for the em28xx bridge, currently only for
NTSC.  Support for PAL capture to follow shortly (including the removal of
numerous hard-coded NTSC-specific sizes for capture buffers, etc).

Note that the code currently changes the default current norm from PAL to
NTSC (so that zvbi-ntsc-cc works properly).  The default norm really should
be moved into a board-level parameter.

      V4L/DVB (12741): em28xx: make video isoc stream work when VBI is enabled · da52a55c
      由 Devin Heitmueller 提交于 
      Add code enabling the VBI registers for variants of the em28xx chip that
support VBI, and make sure the isoc streaming code continues to work for
the video component of the stream (note the video and vbi data arrive
intermixed on the same isoc pipe).

Note that this version just drops the actual VBI data onto the floor as
opposed to processing it.  The "#ifdef 0" tags are for the videobuf code that
appears in the next patch in this series.

We created a separate version of the isoc_copy version for parsing the version
of the stream that includes VBI data.  In theory, they might be able to be
merged at some point in the future, but the initial goal is to ensure that we
do not cause any regressions with devices that do not have VBI support.

      V4L/DVB (12698): em28xx: ir-kbd-i2c init data needs a persistent object · d2ebd0f8
      由 Mauro Carvalho Chehab 提交于 
      ir-kbd-i2c's ir_probe() function can be called much later (i.e. at
ir-kbd-i2c module load), than the lifetime of a struct IR_i2c_init_data
allocated off of the stack in cx18_i2c_new_ir() at registration time.
Make sure we pass a pointer to a persistent IR_i2c_init_data object at
i2c registration time.

Thanks to Brian Rogers, Dustin Mitchell, Andy Walls and Jean Delvare to
rise this question.

Before this patch, if ir-kbd-i2c were probed after em28xx, trash data
were used. After the patch, no matter what order, it is properly
reported as tested by me:

input: i2c IR (i2c IR (EM2840 Hauppaug as /class/input/input10
ir-kbd-i2c: i2c IR (i2c IR (EM2840 Hauppaug detected at i2c-4/4-0030/ir0 [em28xx #0]

      V4L/DVB (12595): common/ir: use a struct for keycode tables · 715a2233
      由 Mauro Carvalho Chehab 提交于 
      Currently, V4L uses a scancode table whose index is the scancode and
the value is the keycode. While this works, it has some drawbacks:

1) It requires that the scancode to be at the range 00-7f;

2) keycodes should be masked on 7 bits in order for it to work;

3) due to the 7 bits approach, sometimes it is not possible to replace
the default keyboard to another one with a different encoding rule;

4) it is different than what is done with dvb-usb approach;

5) it requires a typedef for it to work. This is not a recommended
Linux CodingStyle.

This patch is part of a larger series of IR changes. It basically
replaces the IR_KEYTAB_TYPE tables by a structured table:
struct ir_scancode {
       u16     scancode;
       u32     keycode;
};

This is very close to what dvb does. So, a further integration with DVB
code will be easy.

While we've changed the tables, for now, the IR keycode handling is still
based on the old approach.

The only notable effect is the redution of about 35% of the ir-common
module size:

   text    data     bss     dec     hex filename
   6721   29208       4   35933    8c5d old/ir-common.ko
   5756   18040       4   23800    5cf8 new/ir-common.ko

In thesis, we could be using above u8 for scancode, reducing even more the size
of the module, but defining it as u16 is more convenient, since, on dvb, each
scancode has up to 16 bits, and we currently have a few troubles with rc5, as their
scancodes are defined with more than 8 bits.

This patch itself shouldn't be doing any functional changes.
