2015-11-19[media] media: rc: move check whether a protocol is enabled to the coreHeiner Kallweit10-31/+3
Checking whether a protocol is enabled and calling the related decoder functions should be done by the rc core, not the protocol handlers. Properly handle lirc considering that no protocol bit is set for lirc. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

2015-11-19[media] media: rc: fix decoder module unloadingHeiner Kallweit1-3/+14
Currently, if a decoder module is unloadad, the respective protocol is still shown as enabled (if it was enabled before). Fix this by resetting the respective protocol bits if a decoder module is unloaded.

2015-11-19[media] rc-core: Remove 'struct timeval' usageTina Ruchandani1-10/+9
streamzap uses 'struct timeval' to store the start time of a signal for gap tracking. struct timeval uses a 32-bit seconds representation which will overflow in year 2038 and beyond. Replace struct timeval with ktime_t which uses a 64-bit seconds representation and is 2038 safe. This patch uses ktime_get_real() preserving the use of wall-clock time in the original code.

2015-11-19[media] rc: allow rc modules to be loaded if rc-main is not a moduleRussell King1-1/+1
rc-main mistakenly uses #ifdef MODULE to determine whether it should load the rc keymap modules.

2015-11-19[media] rc: gpio-ir-recv: add timeout on idleEric Nelson1-0/+22
Many decoders require a trailing space (period without IR illumination) to be delivered before completing a decode. Since the gpio-ir-recv driver only delivers events on gpio transitions, a single IR symbol (caused by a quick touch on an IR remote) will not be properly decoded without the use of a timer to flush the tail end state of the IR receiver. This patch initializes and uses a timer and the timeout field of rcdev to complete the stream and allow decode. The timeout can be overridden through the use of the LIRC_SET_REC_TIMEOUT ioctl.

2015-05-14[media] rc: rc-loopback: Add loopback of filter scancodesJames Hogan1-0/+36
Add the s_wakeup_filter callback to the rc-loopback driver, which instead of setting the filter just feeds the scancode back through the input device so that it can be verified.

2015-05-14[media] rc: rc-core: Add support for encode_wakeup driversJames Hogan3-1/+24
Add support in rc-core for drivers which implement the wakeup scancode filter by encoding the scancode using the raw IR encoders. This is by way of rc_dev::encode_wakeup which should be set to true to make the allowed wakeup protocols the same as the set of raw IR encoders. As well as updating the sysfs interface to know which wakeup protocols are allowed for encode_wakeup drivers, also ensure that the IR decoders/encoders are loaded when an encode_wakeup driver is registered.

2015-05-14[media] rc: ir-rc6-decoder: Add encode capabilityAntti Seppälä1-0/+122
Add the capability to encode RC-6 and RC-6A scancodes as raw events. The protocol is chosen based on the specified protocol mask, and whether all the required bits are set in the scancode mask, and none of the unused bits are set in the scancode data. The Manchester modulation helper is used several times with various timings so that RC-6 header preamble, the header, header trailing bit and the data itself can be modulated correctly.

2015-05-14[media] rc: ir-rc5-decoder: Add encode capabilityJames Hogan1-0/+116
Add the capability to encode RC-5, RC-5X and RC-5-SZ scancodes as raw events. The protocol is chosen based on the specified protocol mask, and whether all the required bits are set in the scancode mask, and none of the unused bits are set in the scancode data. For example a scancode filter with bit 16 set in both data and mask is unambiguously RC-5X. The Manchester modulation helper is used, and for RC-5X it is used twice with two sets of timings, the first with a short trailer space for the space in the middle, and the second with no leader so that it can continue the space. The encoding in RC-5-SZ first inserts a pulse and then simply utilizes the generic Manchester encoder available in rc-core.

2015-05-14[media] rc: rc-ir-raw: Add Manchester encoder (phase encoder) helperAntti Seppälä2-0/+118
Adding a simple Manchester encoder to rc-core. Manchester coding is used by at least RC-5 and RC-6 protocols and their variants.

2015-05-14[media] rc: rc-ir-raw: Add scancode encoder callbackJames Hogan2-0/+39
Add a callback to raw ir handlers for encoding and modulating a scancode to a set of raw events. This could be used for transmit, or for converting a wakeup scancode filter to a form that is more suitable for raw hardware wake up filters.
