      [media] media: rc: change 32bit NEC scancode format · 18bc1744
      由 James Hogan 提交于 
      Change 32bit NEC scancode format (used by Apple and TiVo remotes) to
encode the data with the correct bit order. Previously the raw bits were
used without being bit reversed, now each 16bit half is bit reversed
compared to before.

So for the raw NEC data:
  (LSB/First) 0xAAaaCCcc (MSB/Last)
(where traditionally AA=address, aa=~address, CC=command, cc=~command)

We now generate the scancodes:
  (MSB) 0x0000AACC (LSB) (normal NEC)
  (MSB) 0x00AAaaCC (LSB) (extended NEC, address check wrong)
  (MSB) 0xaaAAccCC (LSB) (32-bit NEC, command check wrong)

Note that the address byte order in 32-bit NEC scancodes is different to
that of the extended NEC scancodes. I chose this way as it maintains the
order of the bits in the address/command fields, and CC is clearly
intended to be the LSB of the command if the TiVo codes are anything to
go by so it makes sense for AA to also be the LSB.

The TiVo keymap is updated accordingly.

      [media] rc-core: add separate defines for protocol bitmaps and numbers · c003ab1b
      由 David Härdeman 提交于 
      The RC_TYPE_* defines are currently used both where a single protocol is
expected and where a bitmap of protocols is expected.

Functions like rc_keydown() and functions which add/remove entries to the
keytable want a single protocol. Future userspace APIs would also
benefit from numeric protocols (rather than bitmap ones). Keytables are
smaller if they can use a small(ish) integer rather than a bitmap.

Other functions or struct members (e.g. allowed_protos,
enabled_protocols, etc) accept multiple protocols and need a bitmap.

Using different types reduces the risk of programmer error. Using a
protocol enum whereever possible also makes for a more future-proof
user-space API as we don't need to worry about a sufficient number of
bits being available (e.g. in structs used for ioctl() calls).

The use of both a number and a corresponding bit is dalso one in e.g.
the input subsystem as well (see all the references to set/clear bit when
changing keytables for example).

This patch separate the different usages in preparation for
upcoming patches.

Where a single protocol is expected, enum rc_type is used; where one or more
protocol(s) are expected, something like u64 is used.

The patch has been rewritten so that the format of the sysfs "protocols"
file is no longer altered (at the loss of some detail). The file itself
should probably be deprecated in the future though.

      [media] rc-msi-digivox-ii: Add full scan keycodes · b45681a6
      由 Wolfgang Bail 提交于 
      The ir-rc from my MSI DigiVox mini II Version 3 (af9015) will not work since
kernel 3.2.x.

sudo ir-keytable -t shows:

	1348890734.303273: event MSC: scancode = 317
	1348890734.303280: event key down: KEY_POWER (0x0074)
	1348890734.303282: event sync
	1348890734.553961: event key up: KEY_POWER (0x0074)
	1348890734.553963: event sync
	1348890741.303451: event MSC: scancode = 30d
	1348890741.303457: event key down: KEY_DOWN (0x006c)
	1348890741.303459: event sync
	1348890741.553956: event key up: KEY_DOWN (0x006c)

So I changed in rc-msi-digivox-ii.c { 0x0002, KEY_2 }, to { 0x0302, KEY_2 },
and so on. And now it works well.

      [media] ati_remote: add support for Medion X10 Digitainer remote · 9d454d48
      由 Anssi Hannula 提交于 
      Add support for another Medion X10 remote. This was apparently
originally used with the Medion Digitainer box, but is now sold
separately without any Digitainer labeling.

A peculiarity of this remote is a scrollwheel in place of up/down
buttons. Each direction is mapped to 8 different scancodes, each
corresponding to 1..8 notches, allowing multiple notches to the same
direction to be transmitted in a single scancode. The driver transforms
the multi-notch scancodes to multiple events of the single-notch
scancode.
(0x70..0x77 = 1..8 notches down, 0x78..0x7f = 1..8 notches up)

Since the scrollwheel scancodes are the same that are used for mouse on
some other X10 (ati_remote) remotes, the driver will now check whether
the active keymap has a keycode defined for the single-notch scancode
when a mouse/scrollwheel scancode (0x70..0x7f) is received. If set,
scrollwheel is assumed, otherwise mouse is assumed.

This remote ships with a different receiver than the already supported
Medion X10 remote, but they share the same USB ID. The only difference
in the USB descriptors is that the Digitainer receiver has the Remote
Wakeup bit set in bmAttributes of the Configuration Descriptor.
Therefore that is used to select the default keymap.

Thanks to Stephan Raue from OpenELEC (www.openelec.tv) for providing me
both a Medion X10 Digitainer remote+receiver and an already supported
Medion X10 remote+receiver. Thanks to Martin Beyss for providing some
useful information about the remote (including the "Digitainer" name).
This patch has been tested by both of them and myself.
