V4L/DVB: IR: extend interfaces to support more device settings

2010-08-09T02:43:00Z

LIRC: add new IOCTL that enables learning mode (wide band receiver) Still missing features: carrier report & timeout reports. Will need to pack these into ir_raw_event Signed-off-by: Maxim Levitsky Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: IR: add helper function for hardware with small o/b buffer

2010-08-09T02:43:00Z

Some ir input devices have small buffer, and interrupt the host each time it is full (or half full) Add a helper that automaticly handles timeouts, and also automaticly merges samples of same time (space-space) Such samples might be placed by hardware because size of sample in the buffer is small (a byte for example). Also remove constness from ir_dev_props, because it now contains timeout settings that driver might want to change Signed-off-by: Maxim Levitsky Acked-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: IR: Allow not to compile keymaps in

2010-08-09T02:43:00Z

Currently, ir device registration fails if keymap requested by driver is not found. Fix that by always compiling in the empty keymap, and using it as a failback. Signed-off-by: Maxim Levitsky Acked-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: IR TX: incoming IR buffer now an int pointer

V4L/DVB: ir-core: change duration to be coded as a u32 integer

2010-05-19T15:57:42Z

This patch implements the agreed upon 1:31 integer encoded pulse/duration struct for ir-core raw decoders. All decoders have been tested after the change. Comments are welcome. Signed-off-by: David Härdeman Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: ir-core: make ir_g_keycode_from_table a public function

2010-05-19T15:57:40Z

The imon driver I've previously submitted and have been porting to use ir-core needs to use ir_g_keycode_from_table, as ir_keydown is not sufficient, due to these things having really oddball hardware decoders in them. This just moves the function declaration from ir-core-priv.h over to ir-core.h. Signed-off-by: Jarod Wilson Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: ir-core: move subsystem internal calls to ir-core-priv.h

2010-05-19T15:57:04Z

ir-core.h has the kABI to be used by the bridge drivers, when needing to register IR protocols and pass IR events. However, the same file also contains IR subsystem internal calls, meant to be used inside ir-core and between ir-core and the raw decoders. Better to move those functions to an internal header, for some reasons: 1) Header will be a little more cleaner; 2) It avoids the need of recompile everything (bridge/hardware drivers, etc), just because a new decoder were added, or some other internal change were needed; 3) Better organize the ir-core API, splitting the functions that are internal to IR core and the ancillary drivers (decoders, lirc_dev) from the features that should be exported to IR subsystem clients.

V4L/DVB: Teach drivers/media/IR/ir-raw-event.c to use durations

2010-05-19T15:57:03Z

drivers/media/IR/ir-raw-event.c is currently written with the assumption that all "raw" hardware will generate events only on state change (i.e. when a pulse or space starts). However, some hardware (like mceusb, probably the most popular IR receiver out there) only generates duration data (and that data is buffered so using any kind of timing on the data is futile). Furthermore, using signed int's to represent pulse/space durations is a well-known approach when writing ir decoders. With this patch: - s64 int's are used to represent pulse/space durations in ns - a workqueue is used to decode the ir protocols outside of interrupt context - #defines are added to make decoders clearer - decoder reset is implemented by passing a zero duration to the kfifo queue and decoders are updated accordingly Signed-off-by: David Härdeman Signed-off-by: Mauro Carvalho Chehab

V4L/DVB: ir-core: Distinguish sysfs attributes for in-hardware and raw decoders

2010-05-19T15:57:02Z

Some devices have in-hardware Remote Controller decoder, while others need a software decoder to get the IR code. As each software decoder can be enabled/disabled individually, allowing multiple protocol decoding capability. On the other hand, hardware decoders have a limited protocol support, often being able of decoding just one protocol each time. So, each type needs a different set of capabilities to control the supported protocol(s). Signed-off-by: Mauro Carvalho Chehab
