do we need regmap-i2c in barebox?

I have made draft version of pcf85363 i2c rtc driver for barebox.
I used drivers/rtc/rtc-pcf85363.c from linux kernel as a prototype.
The linux driver uses REGMAP_I2C linux feature. Barebox has regmap
framework, but no special i2c regmap features.

In barebox source tree I have found drivers/mfd/stpmic1.c which
uses regmap for i2c device without REGMAP_I2C linux feature.
So I have just stolen i2c regmap code from stpmic1.c for pcf85363
driver. I'll send pcf85363 i2c rtc driver for barebox in a separate

Is there any sense in porting drivers/base/regmap/regmap-i2c.c from
linux into barebox?
