* [media] dib0700: avoid the risk of forgetting to add the adapter's sizeMauro Carvalho Chehab2015-05-141-82/+35
| | | | | | | | | | | | | | | | | 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. Better to use a macro that would do it for us, at least while this is not converted to dvb-usb-v2. Compile-tested only. Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

* [media] rc: rc-core: Add support for encode_wakeup driversJames Hogan2015-05-143-1/+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.

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

| | | | | | | | | | | | | Converting debug prints to use pr_foo() is not trivial, as the result will be a way worse than what's provided here, due to the pieces of the code that prints the I2C transfers. Those use a lot pr_cont(), and, depending on using either level 1 or 2, a different set of macros are selected.

* [media] saa7134: better handle core debug messagesMauro Carvalho Chehab2015-05-131-35/+33
| | | | | | | | | | | | | | | | | | | On media drivers, debugging messages should be grouped into categories, as this makes easier to debug the driver. In the case of saa7134, the core has 2 debug categories, one for IRQ, and another one for the core itself. The IRQ have actually 2 levels of debug. So, instead of using pr_dbg(), where everything would be in the same box, let's define two macros that use pr_fmt(), one for the core, and another one for irq. With that, we can replace the remaining printk() occurrences at the core to use either core_dbg() or irq_dbg(), depending on the group of debug macros that need to be enabled.
