* [media] cx24120: i2c-max-write-size is now configurablePatrick Boettcher2015-05-183-16/+26
| | | | | | | | | Some i2c-hosts are quite limited regarding maximum i2c-burst-write-sizes. This patch makes the previously hardcoded field configurable by users of the driver.

* [media] Add support for TechniSat Skystar S2Jemma Denson2015-05-188-7/+1688
| | | | | | | | | | | | | | | | | | | | | This patch adds support for the Technisat Skystar S2 - this has been tried before but the cx24120 driver was a bit out of shape and it didn't got any further: https://patchwork.linuxtv.org/patch/10575/ It is an old card, but currently being sold off for next to nothing, so it's proving quite popular of late. Noticing it's quite similar to the cx24116 and cx24117 I've rewritten the driver in a similar way. There were a few registers and commands from those drivers missing from this one I've tested out and found they do something so they've been added in to speed up tuning and to make get_frontend return something useful.

| | | | | | | | | | | | | | | | | For every frontend entry, we need to add the adapter's size. There are already two patches fixing it. So, it doesn't seem trivial to keep it there at the right place. Also, currently, the indentation is wrong on all places. So, it seems that keeping it right is not too trivial.

* [media] rc: rc-core: Add support for encode_wakeup driversJames Hogan2015-05-144-1/+27
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | 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.

* [media] rc: ir-rc5-decoder: Add encode capabilityJames Hogan2015-05-141-0/+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.
