There's one comment that has been copied from bttv to many other
media/video drivers:
/* init + register i2c algo-bit adapter */
Meanwhile, many drivers use hardware I2C implementations instead of
relying on i2c-algo-bit, so this comment is misleading. Remove the
reference to "algo-bit" from all drivers, to avoid any confusion. This
is the best way to ensure that the comments won't go out of sync
again. Anyone interested in the implementation details would rather
look at the code itself.

The rc-hauppauge-new map is a messy thing, as it bundles 3
different remote controllers as if they were just one,
discarding the address byte. Also, some key maps are wrong.
With the conversion to the new rc-core, it is likely that
most of the devices won't be working properly, as the i2c
driver and the raw decoders are now providing 16 bits for
the remote, instead of just 8.

With the v4l2_i2c_new_subdev* functions now supporting loading modules
based on modaliases, replace the hardcoded module name passed to those
functions by NULL.
The sub-devices without a listed module name don't result in and I2C
sub-device being created, as they either are IR devices or don't have an
I2C address listed. It's thus safe to rely on modaliases only.
All corresponding I2C modules have been checked, and all of them include
a module aliases table with names corresponding to what the cx18 driver
uses.

Instead of using the ugly keymap sequences, use the new rc-*.ko keymap

assignment for IR init

persistent object
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 for pointing out a solution, and Dustin Mitchell for
testing against a 2.6.30 kernel.

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.

to new_(probed)_subdev
The functions v4l2_i2c_new_subdev and v4l2_i2c_new_probed_subdev relied on
i2c_get_adapdata to return the v4l2_device. However, this is not always

v4l2_subdevices
Convert GPIO line functions, such a audio routing and device resets, to
v4l2_subdevices. This essentially completes the conversion of cx18 to the

instead of ID.
Since the i2c driver ID will be removed in the near future we have to
modify the v4l2 debugging API to use the driver name instead of driver ID.
Note that this API is not used in applications other than v4l2-dbg.cpp
as it is for debugging and testing only.
Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged
with a warning that it is deprecated and will be removed in 2.6.30.

Update all the remaining new-style i2c drivers to use standard module
aliasing instead of the old driver_name/type driver matching scheme.
Note that the tuner driver is a bit quirky at the moment, as it
overwrites i2c_client.name with arbitrary strings. We write "tuner"
back on remove, to make sure that driver cycling will work properly,
but there may still be troublesome corner cases.
