[PATCH v2 0/2] pinctrl: mcp23s08: Fix probe issues

[Judith Mendez]

MCP23S18 driver probe failures on AM62L3 BeagleBadge[0].

Fix MCP23S18 probe failures found with BeagleBadge which has a MCP23S18
on board chip. Fixes are made up of initializing chip data before regmap
init, and using device_property_read_u8 to match binding spec. First fix
prevents kernel oops and second fix prevents MCP chip probe failure.
