common/ir: use a struct for keycode tables

2009-08-29T17:15:55+00:00

From: Mauro Carvalho Chehab 

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.

Add remote support to cph03x bttv card

2009-08-22T17:43:50+00:00

From: Mauro Carvalho Chehab 

Hello kernel developers.
I found a bug report from an user in launchpad. I just copy it here. It
includes patch.

I don't own the necessary hardware to test it but the patch looks
trivial.

I'm not subscribed to this list, so please CC me. Thanks!

Here is the text:


"""
remote control for my tv card doesnt work

I have Askey CPH03x TV Capturer.
When I load bttv module with "card=59" option which is proper for this
tv card,
I can watch tv with sound but my remote control doesnt work. There is no
ir

When bttv module is loaded with "card=137" option remote control works
very
well.

v4l: simplify v4l2_i2c_new_subdev and friends

2009-08-10T05:49:08+00:00

From: Hans Verkuil 

Rewrite v4l2_i2c_new_subdev as a simplified version of v4l2_i2c_new_subdev_cfg
and remove v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr.

This simplifies this API substantially.

Stop defining I2C adapter IDs nobody uses

2009-06-19T19:56:56+00:00

From: Jean Delvare 

There is no point in defining I2C adapter IDs when no code is using
them. As this field might go away in the future, stop using it when
we don't need to.

    headers: smp_lock.h redux

    * Remove smp_lock.h from files which don't need it (including some headers!)
    * Add smp_lock.h to files which do need it
    * Make smp_lock.h include conditional in hardirq.h
      It's needed only for one kernel_locked() usage which is under CONFIG_PREEMPT

      This will make hardirq.h inclusion cheaper for every PREEMPT=n config
      (which includes allmodconfig/allyesconfig, BTW)

bttv: fix regression: tvaudio must be loaded before tuner

2009-07-20T11:14:17+00:00

From: Hans Verkuil 

Both tvaudio and the tuner share i2c address 0x42. The tvaudio module can
check whether it really is a tda9840, but the tuner can't. So the tvaudio
module must be loaded before the tuner module. This was also the case for
2.6.29, but the order was swapped in 2.6.30.

Thanks to Krzysztof Grygiencz for reporting and testing this.
