Hi,

This is a rebased version against the media_tree staging/v2.6.37

Best regards,

[PATCH 1/5] IR: extend and sort the MCE keymap

[Maxim Levitsky]

Add new keys, found on:

Toshiba Qosmio F50-10q.
Toshiba Qosmio X300
Toshiba A500-141

Also sort the keytable by scancode number as that makes sense
and alows easily to add new keycodes.

Thanks to:
Sami R <maesesami-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Alexander Skiba <ghostlyrics-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
Jordi Pelegrin <pelegrin.jordi-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

For reports and testing.

[PATCH 2/5] IR: extend ir_raw_event and do refactoring

[Maxim Levitsky]

Add new event types for timeout & carrier report
Move timeout handling from ir_raw_event_store_with_filter to
ir-lirc-codec, where it is really needed.
Now lirc bridge ensures proper gap handling.
Extend lirc bridge for carrier & timeout reports

Note: all new ir_raw_event variables now should be initialized
like that: DEFINE_IR_RAW_EVENT(ev);

To clean an existing event, use init_ir_raw_event(&ev);

Too much fails for me... -EABORTING...

I won't apply this patch... there are two copies of it, and it has several broken hunks.


Please fix.

Not surprising as v4l tree got many changes and that patch touches many
places.

Will redo that really against the media_tree :-)
Sorry!

[PATCH 3/5] IR: ene_ir: few bugfixes

[Maxim Levitsky]

This is a result of last round of debug with
Sami R <maesesami-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>.

Thank you Sami very much!

The biggest bug I fixed is that,
I was clobbering the CIRCFG register after it is setup
That wasn't a good idea really

And some small refactoring, etc.

Looks sane, though I'd prefer to see symbolic bit names or some such thing
here instead of 0x63. Not something to hold up the patch though.

63 isn't a bitfileld, but rather two numbers.
3 is number of carrier pulses to skip, and 6 is number of carrier pulses
to average.

I have a note about that in header.

Ah, so you do. Apologies then. Personally, I'd probably document that next
to the 0x63 as well, just so readers who neglect to go find the register
define and discover the comment there don't think the same as me. ;)

Spacing is a bit odd here (random indent, no newline), but meh, looks sane
otherwise.

Hmm... shouldn't it be in the patch that adds DEFINE_IR_RAW_EVENT(ev) ?

This way, it will likely break git bisect.

Anyway, as patch 2/5 weren't applied, I can't apply this one either.

the other 2 patches were applied.

[PATCH 5/5] IR: ene_ir: don't upload all settings on each TX packet.

[Maxim Levitsky]

This is just unnessesary, and now more logical

Also lot of refactoring
