gpio: syscon: retrive syscon node and regs offsets from dt
This patch adds handling of new "gpio,syscon-dev" DT property,
which allows to specify syscon node and data/direction registers
offsets in DT.
"gpio,syscon-dev" has following format:
gpio,syscon-dev = <&syscon_dev data_reg_offset [direction_reg_offset]>;
where
- syscon_dev - phandle on syscon node
- data_reg_offset - offset of data register (in bytes)
- direction_reg_offset - offset of dirrection register (optional, in bytes)
for example:
gpio,syscon-dev = <&devctrl 0x254>;
In such way, the support of multiple Syscon GPIO devices is added.
