Hello,
This series adds support for a variant of the ISC named XISC.
This block is present in the product named sama7g5.
I started by moving code around, the code which was specialized for sama5d2
type of ISC, to have it inside the dedicated sama5d2 file.
I added several new pipeline elements to the code base, which would be common
to sama5d2 and the new sama7g5, but only used by the new style pipeline.
I separated the input and output formats on a per-product separate array.
I added the new sama7g5 compatible driver for the xisc, which is similar with
the sama5d2, but with differences in terms of DT, clocks and callbacks to
specific operations.
I added the binding for the xisc by copying and modifying the existing
isc one. I know that it has to be converted to yaml, and I will do that if
it looks good.
Feedback is appreciated.
Thanks,
Eugen
Changes in v2:
- Fixed krobot warnings with W=1 regarding functions with no prototype
- Fixed new sama7g5 driver to use the new subdev fwnode API in kernel 5.12. my driver was
based on old 5.10 style API.
