| * [media] rc: interim support for 32-bit NEC-ish scancodesJarod Wilson2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Apple and TiVo remotes I've got use an NEC-ish protocol, but rather than a command/not_command pair, they have what appear to be vendor ID bytes. This change makes the NEC decoder warn if the command/not_command checksum fails, but then passes along a full 32-bit scancode for keymap lookup. This change should make no difference for existing keymaps, since they simply won't have 32-bit scancodes, but allows for a 32-bit keymap. At the moment, that'll have to be uploaded by the user, but I've got Apple and TiVo remote keymaps forthcoming. In the long run (2.6.40, hopefully), we should probably just always use all 32 bits for all NEC keymaps, but this should get us by for 2.6.39. (Note that a few of the TiVo keys actuallly *do* pass the command checksum, so for now, the keymap for this remote will have to be a mix of 24-bit and 32-bit scancodes, but so be it).

As the Hauppauge Black is now part of the hauppauge keymap, just remove it. Also, remove the modprobe hacks to select between the Gray and the Black versions of the remote controller as: - Both are supported by default by the keymap; - If the user just wants one keyboard supported, it is just a matter of changing the keymap via the userspace tool (ir-keytable), removing the keys that he doesn't desire. As ir-keytable auto-loads the keys via udev, this is better than obscure modprobe parameters. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Jarod Wilson <jarod@redhat.com>
| * [media] remove the old RC_MAP_HAUPPAUGE_NEW RC mapMauro Carvalho Chehab2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. delete mode 100644 drivers/media/rc/keymaps/rc-hauppauge-new.c Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Jarod Wilson <jarod@redhat.com>
| * [media] rc/keymaps: Rename Hauppauge table as rc-hauppaugeMauro Carvalho Chehab2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are two "hauppauge-new" keymaps, one with protocol unknown, and the other with the protocol marked accordingly. However, both tables are miss-named. Also, the old rc-hauppauge-new is broken, as it mixes three different controllers as if they were just one. This patch solves half of the problem by renaming the correct keycode table as just rc-hauppauge. This table contains the codes for the four different types of remote controllers found on Hauppauge cards, properly mapped with their different addresses. create mode 100644 drivers/media/rc/keymaps/rc-hauppauge.c delete mode 100644 drivers/media/rc/keymaps/rc-rc5-hauppauge-new.c [Jarod: fix up RC_MAP_HAUPPAUGE defines] Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Jarod Wilson <jarod@redhat.com>

| * [media] rc: New rc-based ite-cir driver for several ITE CIRsJuan J. Garcia de Soria2011-03-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a second version of an rc-core based driver for the ITE Tech IT8712F CIR and now for a pair of other variants of the IT8512 CIR too. This driver should replace the lirc_it87 and lirc_ite8709 currently living in the LIRC staging directory. The driver should support the ITE8704, ITE8713, ITE8708 and ITE8709 (this last one yet untested) PNP ID's. The code doesn'te reuse code from the pre-existing LIRC drivers, but has been written from scratch using the nuvoton.cir driver as a skeleton. This new driver shouldn't exhibit timing problems when running under load (or with interrupts disabled for relatively long times). It works OOTB with the RC6 MCE remote bundled with the ASUS EEEBox. TX support is implemented, but I'm unable to test it since my hardware lacks TX capability. Signed-off-by: Juan J.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the code in saa7134-input is not a module, but the config for it is set as a boolean instead of a tristate, this causes a strange dependency on RC_CORE. VIDEO_SAA7134_RC (which determines if saa7134-input.o is built) depends on RC_CORE and VIDEO_SAA7134. If VIDEO_SAA7134 is compiled as 'y' but RC_CORE is compiled as 'm' VIDEO_SAA7134_RC can still be set to 'y' which causes undefined symbols that it needs from RC_CORE. The simplest solution is to not allow VIDEO_SAA7134_RC be enabled if RC_CORE compiled as a module (m) and VIDEO_SA7134 is compiled into the kernel (y).
