ISO compliant SSP config
According to ISO can fd spec. SSP offset should be configured from beginning of bit time in user interface. Right now it is configured from Sample point.
- Change description in IPxact.
- Subtract tseg1 duration from ssp offset in reg.map. This can be done in ssp module inside of bus_sampling.
- Add DBT time Quanta edge to bus sampling forcing ssp shift reg to shift only when aligned to time quanta. Thisway the value in ssp offset will change from clock cycles to time quanta.
- Describe a section in the docs on how to configure SSP. Preferably with some diagrams.
After this issue is resolved, viktor may implement ssp_cfg test. Note that adding ssp support to driver is not blocked by this issue since ssp_offset field will not change. Only its meaning will change...
