* [media] drxk_hard: Don't use CamelCaseMauro Carvalho Chehab2013-06-08
| | | | | | | | | | | | X-Patchwork-Delegate: mchehab@redhat.com Thare are lots of CamelCase warnings produced by checkpatch.pl. This weren't fixed at the time the driver got submitted due to the lack of manpower do to such cleanup. Now that I have one script that automates this task, cleans it. That makes the driver almost checkpatch-compliant, except for 80 column warnings. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | Hi, This patch uses the driver from openpli[1] as a template to restore the remote control support. I had to divert from the original to use the in kernel rc protocol decoder. The key repetition does, not seem to work but I cant find the problem in the driver. As a raw rc provider, no key table is hardcoded. Rodrigo.

* [media] stb0899: fix inversion enum values to match usage with CFRReinhard Nißl2013-06-08
| | | | | | | | | | | | | | | | | | | Throughout the zig-zag-implementations, inversion is taken into account when reading and writing the CFR register, which contains the derotator frequency. As swapping IQ signals changes the sign of that register for example, the idea is to compensate that sign change by multiplying the register value with the inversion enum value. The current enum values 0 and 1 for IQ_SWAP_OFF and IQ_SWAP_ON don't work in the case IQ_SWAP_OFF, due to the multiplication by zero (I've only found a single device which actually uses IQ_SWAP_OFF in it's config). I've changed the enum values to +1 and -1 to accommodate to the intended usage.

* [media] stb0899: enable auto inversion handling unconditionallyReinhard Nißl2013-06-08
| | | | | | | | | | | | | It seems that current inversion handling addresses only the signal routing on the PCB, i. e. IQ signals are either swapped or not. But when the device is operated in a Satellite Channel Router (SCR) environment, an additional inversion is required due to the way how the SCR works. Therefore it makes sense to me to always enable auto inversion handling and drop the enum value IQ_SWAP_AUTO.

| | | | | | | | | | | | | | | | | | | This patch adds a list of supported codecs per device type which is used to determine the allowed pixel formats and maximum frame sizes depending on the possible codecs. It allows frame sizes larger than 720 x 576 on CODA7 and adds support for the YVU420 (planar YUV 4:2:0 with switched Cb and Cr) format. Other uncompressed formats that could be added in the future are the chroma interleaved NV12 and NV21 formats and the multiplanar variants YUV420M, YVU420M, NV12M, and NV21M. Further, rawstreamon is renamed to streamon_out and compstreamon is renamed to streamon_cap in preparation for decoding support. The maximum encoded frame buffer size is increased to 1 MiB. Instead of tracking inst_type and codec across S_FMT calls, set the codec and inst_type in start_streaming.
