Read from external RTC while booting in AM3354 custom board

Other Parts Discussed in Thread: BQ32000Hi, I have connected external RTC BQ32000 to I2C2 lines of am335x. To the same I2C bus, touch screen is also connected. I guess, by default date and time is read from the internal RTC. It is currently reading from rtc0. I want to change it to external RTC. I have muxed uart1_ctsn.i2c2_sda and uart1_rtsn.i2c2_scl pins and added BQ32k to the i2c_boardinfo structure and configured BQ32000 driver through menuconfig. But only touch screen gets detected on the i2c2 bus when booted. What I am missing? How to make BQ32000 to get detected on bus. Regards, Pradeep
