2010-06-01V4L/DVB: Bug fix: make IR work again for dm1105Igor M. Liplianin
It makes IR to work again for dm1105 and, possibly, others. Signed-off-by: Igor M. Liplianin <liplianin@me.by> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-05-19V4L/DVB: ir-core: remove IR_TYPE_PDDavid Härdeman
Pulse-distance is not a protocol, it is a line coding (used by some protocols, like NEC). Looking at the uses of IR_TYPE_PD, the real protocol seems to be NEC in all cases (drivers/media/video/cx88/cx88-input.c is the only user). So, remove IR_TYPE_PD while it is still easy to do so.

2010-05-19V4L/DVB: ir-core: move subsystem internal calls to ir-core-priv.hMauro Carvalho Chehab
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.

2010-05-19V4L/DVB: ir-core: properly present the supported and current protocolsMauro Carvalho Chehab
Hardware decoders have a more limited set of decoders than software ones. In general, they support just one protocol at a given time, but allow changing between a few options. Rename the previous badly named "current_protocol" as just "protocol", meaning the current protocol(s) accepted by the driver, and add a "support_protocols" to represent the entire universe of supported protocols by that specific hardware. As commented on http://lwn.net/Articles/378884/, the "one file, one value" rule doesn't fit nor does make much sense for bitmap or enum values. So, the supported_protocols will enum all supported protocols, and the protocol will present all active protocols. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-05-19V4L/DVB: ir-core: Distinguish sysfs attributes for in-hardware and raw decodersMauro Carvalho Chehab
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 <mchehab@redhat.com>
2010-05-19V4L/DVB: rename sysfs remote controller devices from rcrcv to rcDavid Härdeman
When the remote controller class is anyway being renamed from ir to rc this would be a good time to also rename the devices from rcrcvX to rcX. I know we haven't reached any agreement on whether transmission will eventually be handled by the same device, but this change will at least make the device name non-receive-specific which will make it possible in the future (and if a different approach is finally agreed upon, the device name still works).

2010-05-19V4L/DVB: ir-core: Make use of the new IR keymap modulesMauro Carvalho Chehab
Instead of using the ugly keymap sequences, use the new rc-*.ko keymap files. For now, it is still needed to have one keymap loaded, for the RC code to work. Later patches will remove this depenency. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-05-18V4L/DVB: ir-core: rename sysfs remote controller class from ir to rcMauro Carvalho Chehab
IR is an alias for Infrared Remote, while RC is an alias for Remote Controller. While currently all implementations are with Infrared Remote Controller, this subsystem is not meant to be used only by IR type of RC's. So, as discussed on both linux-media and linux-input, the better is to rename the subsystem as Remote Controller. While, currently, the only application that uses the /sys/class/irrcv is ir-keytable application, and its sysfs support works only with the current linux-next code, it is still possible to change the userspace API without the risk of breaking applications. So, better to rename this sooner than later. Later patches will be needed to rename the files and to move them away from drivers/media, but this is not a critical issue. So, for now, let's just change the name of the sysfs class/nodes. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2010-05-18V4L/DVB: ir-core: dynamically load the compiled IR protocolsMauro Carvalho Chehab
Instead of hardcoding the protocols into ir-core, add a register interface for the IR protocol decoders, and convert ir-nec-decoder into a client of ir-core. With this approach, it is possible to dynamically load the needed IR protocols, and to add a RAW IR interface module, registered as one IR raw protocol decoder. This patch opens a way to register a lirc_dev interface to work as an userspace IR protocol decoder. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2010-05-18V4L/DVB: ir: use a real device instead of a virtual classMauro Carvalho Chehab
Change the ir-sysfs approach to create irrcv0 as a device, instead of using class_dev. Also, change the way input is registered, in order to make its parent to be the irrcv device. Due to this change, now the event device is created under /sys/class/ir/irrcv class: /sys/class/irrcv/irrcv0/ |-- current_protocol |-- device -> ../../../1-3 |-- input9 | |-- capabilities | | |-- abs ...

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Add sysfs skeleton to export remote controller information via /sys/class/irrcv. For now, the code doesn't do much. It just exports an attribute that is meant to report and control the IR protocol used by the keytable. However, the callbacks for this new attribute weren't set yet. Also, it lacks symlinks to the used event interface. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
