[PATCH 0/4] pinctrl: mcp23s08 fixes

[Jan Kundrát <jan.kundrat@xxxxxxxxx>]

My HW has two physical chips on the same SPI CS, and that's a bit
problematic. I've already solved conflicts in, e.g., debugfs entries for
pinctrl and made it possible to distinguish the chip labels, but there
was no way of attaching names to the individual GPIO lines from the DT.
One approach suggested by Phil back in February [1] was to introduce
intermediate nodes to the DT.

Jan Kundrát (4):
  pinctrl: mcp23s08: Do not complain about unsupported params
  pinctrl: mcp23s08: Kconfig: update to reflect supported features
  pinctrl: mcp23s08: debugfs: Do not restore the INTF register
  pinctrl: mcp23s08: work around GPIO line naming
