Subject: [PATCH v4 0/2] pinctrl: ocelot: Add fixes for ocelot driver

The patch series fixes 2 issues with pincfg.
- first issue is that on lan966x uses different offsets than sparx5
  so it can't use directly the ocelot_confops
- second issue is pincfg stop working when regmap support was added.

v3->v4:
- add missing check for NULL pointer when doing devm_kmemdup
- remove devm_kmemdup for pincfg_data as it can be const
- remove has_schmitt field, because we can use schmitt_bit for checking
  if it has support for PIN_CONFIG_INPUT_SCHMITT_ENABLE
- change the declaration of ocelot_pinctrl_create_pincfg

v2->v3:
- reorder ocelot_pincfg_data fields, mandatory fields go first
- move the field pincfg_data inside ocelot_pinctrl
- add back max_register for regmap_config for pincfg.
- make struct ocelot_match_data const and drop the cast.

v1->v2:
- use regmap_get_reg_stride instead of making regmap_config global
- update how ocelot_match_data structs are initialized

Horatiu Vultur (2):
  pinctrl: ocelot: Fix pincfg for lan966x
  pinctrl: ocelot: Fix pincfg
