Hi Oleksij,
Do we have any support for regular expression support for the
regmap_reg_range, since all the ports have same register configuration
except the port number in the msb. Becaue If I need to add regmap
validation for lan937x which has 5 variant with port count from 4 to 8
it will increase the file size. Do we need to move the register map to
other file or adding in ksz_common.c itself is fine.
