The series add support for the serial GPIO controller used by
Microchip Sparx5, as well as (MSCC) ocelot/jaguar2 SoCs.
v6 changes:
- Use "bus-frequency" instead of "microchip,sgpio-frequency". Drop
'$ref'. (Robh)
- Added "ngpios" description, bumped minimum to 32. (Linus)
- Added "#size-cells" description. (Linus)
- Changed "bus-frequency" validation in driver to reflect the YAML
description.
v5 changes (driver comments from Linus):
- Collect bank data in sgpio_bank struct
- Add is_input boolean to sgpio_bank struct
- Use single-bit bitmasks in sgpio_output_set() and sgpio_output_get()
- Eliminate superfluous struct pinctrl_dev *pctl_dev in bank data
- Fix wrong ngpio consistency check
v4 changes (binding comments from Rob):
- microchip,sgpio-port-ranges changed to uint32-matrix so tuples can
be represented properly.
- gpio controller node name changed to "gpio@[0-1]"
- whitespace fixes
- DT files updated as per schema changes
v3 changes:
- Renamed all usage of "mchp" abbrevation with "microchip".
- Split the in/output directions into (two) separate banks.
- Eliminated the bindings include file (from above)
- Changed SPDX license to "GPL-2.0-or-later"
- Change -ENOTSUPP to -EOPNOTSUPP
- Minor type/symbol naming changes
v2 changes:
- Adds both in and output modes.
- Use direct adressing of the individual banks (#gpio-cells = <4>),
also osoleting need for addressing macros in bindings include file.
- Property 'microchip,sgpio-ports' (uint32, bitmask) replaced by
proper range set (array of [start,end]) 'microchip,sgpio-port-ranges'.
- Fixes whitespace issues in Kconfig file
