* | media: ddbridge: split code into multiple filesDaniel Scheller2017-08-096-577/+710
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of 0.9.9b, the ddbridge code has been split from one single file (ddbridge-core.c) into multiple files, with the purpose of taking care of different topics, and to be able to reuse code in different kernel modules (ddbridge.ko and octonet.ko). This applies the same code split, with a notable difference: In the vendor package, the split was done by moving all code parts into separate files, and in the "main" code files (ddbridge.c and octonet.c), a simple "#include ddbridge-core.c" was done. In this patch, the same split (codewise) is done, but all resulting .c/.o files will be handled by the makefile, with proper prototyping of all shared functions done in ddbridge.h. To avoid conflicts wrt the global space, the I2C functions and necessary prototypes for ddbridge-i2c.c are moved into ddbridge-i2c.h, which is to be included wherever required.

* | media: ddbridge: move/reorder functionsDaniel Scheller2017-08-091-331/+325
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions in ddbridge-core.c have been moved to different positions in newer versions of the dddvb vendor driver package (most notably in version 0.9.9b). Perform the same code move to keep the diff of the upcoming code bump simpler.

* | media: solo6x10: export hardware GPIO pins 8:31 to gpiolib interfaceAnton Sviridenko2017-08-092-0/+102
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 24 GPIO pins from 32 available on solo6x10 chips are exported to gpiolib. First 8 GPIOs are reserved for internal use on capture card boards, GPIOs in range 8:15 are configured as outputs to control relays, remaining 16:31 are configured as inputs to read sensor states. Now with this patch userspace DVR software can switch relays and read sensor states when GPIO extension cards are attached to Softlogic solo6x10 based video capture cards.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replace the copy and the silence ops with the new PCM ops. The device supports only 1 channel and 8bit sample, so it's always bytes=frames, and we need no conversion of unit in the callback. Also, it's a capture stream, thus no silence is needed.
