Is it possible to keep existing driver drivers/i2c/busses/i2c-aspeed.c for ast2400/ast2500, while move ast2600 support to new driver altogether, say i2c-ast2600.c along with new register mode? By default new driver can support legacy mode with same compatible "aspeed,ast2600- i2c-bus", additionally driven by dt props, switch to new mode.
