* media: venus: hfi_parser: add common capability parserStanimir Varbanov2018-07-251-337/+19
| | | | | | | | | | | | This adds common capability parser for all supported Venus versions. Having it will help to enumerate better the supported raw formats and codecs and also the capabilities for every codec like max/min width/height, framerate, bitrate and so on.

Instead, on first error, we should probably just bail out. Other option is to increment read_bytes by sizeof(u32) before the switch, rather than only accounting for the ptype header in the non-error case. Note that in this case it is HFI_ERR_SYS_INVALID_PARAMETER, ie. an unrecognized/unsupported parameter, so interpreting the next word as a property type would be bogus. The other error cases are due to truncated buffer, so there isn't likely to be anything valid to interpret in the remainder of the buffer. So just bailing seems like a reasonable solution.

* [media] media: venus: hfi: add Host Firmware Interface (HFI)Stanimir Varbanov2017-06-201-0/+1054
This is the implementation of HFI. It is charged with the responsibility to comunicate with the firmware through an interface commands and messages. - hfi.c has interface functions used by the core, decoder and encoder parts to comunicate with the firmware. For example there are functions for session and core initialisation. - hfi_cmds has packetization operations which preparing packets to be send from host to firmware. - hfi_msgs takes care of messages sent from firmware to the host.
