Hi Steven,

In the current driver design, the max number of sgpio pins is hardcoded
in macro MAX_NR_HW_SGPIO and the value is 80.

For supporting sgpio master interfaces of AST2600 SoC, the patch series
contains the following enhancement:
- Convert txt dt-bindings to yaml.
- Update aspeed dtsi to support the enhanced sgpio.
- Get the max number of sgpio that SoC supported from dts.
- Support muiltiple SGPIO master interfaces.
- Support up to 128 pins.

Changes from v1:
* Fix yaml format issues.
* Fix issues reported by kernel test robot.

Please help to review.

I think it's worth leaving a little more time between sending series.

I've just sent a bunch of reviews on v1.

Cheers,

Andrew
