iMX25 external RTC

[Venku]

Hello I am trying to use an external RTC (m41t81s). Enabled this option under RTC in menuconfig, didn't yield any results. No device under /dev for rtc, neither an entry in sys/bus..

Under I2C RTC, have enabled M41t80.

I have removed the DryIce RTC.

Are there any tweaks reqd in BSP for this to run?

Update : RTC works

mxc25_3stack.c:

i2c_board_info mxc_i2c_board_info __initdata = {
{
.type = "m41t81s",
.addr = 0x68,
},

entry for this i2c device was reqd in the structure for it to work..
