-config ETRAX_RTC

- Enables drivers for the Real-Time Clock battery-backed chips on
- some products. The kernel reads the time when booting, and
- the date can be set using ioctl(fd, RTC_SET_TIME, &rt) with rt a
- rtc_time struct (see <file:arch/cris/include/asm/rtc.h>) on the
- /dev/rtc device. You can check the time with cat /proc/rtc, but
- normal time reading should be done using libc function time and
- friends.

Bit set = changeable.
You probably want 00 here.

- If your product has the RST signal line for the DS1302 RTC on the
- Generic Port then say Y here, otherwise leave it as N in which
- case the RST signal line is assumed to be connected to Port PB
- (just like the SCL and SDA lines).

- This controls the initial value of the trickle charge register.
- 0 = disabled (use this if you are unsure or have a non rechargeable battery)
- Otherwise the following values can be OR:ed together to control the
- charge current:
- 1 = 2kohm, 2 = 4kohm, 3 = 4kohm
- 4 = 1 diode, 8 = 2 diodes
- Allowed values are (increasing current): 0, 11, 10, 9, 7, 6, 5
