I've got four devices on i2c that I need to read. Simple thermal and
voltage monitors. I2c works fine in uboot, and now I'm trying to get things
to work in linux.
In the kernel .config I enable
I2C
and
I2C_MPC
During the platform boot code:
I init the IO ports for i2c, (same as ep8248e code)
{3, 14, CPM_PIN_INPUT | CPM_PIN_SECONDARY},
{3, 15, CPM_PIN_INPUT | CPM_PIN_SECONDARY},
__Do I need to configure a brg for the i2c along with the other devices ?
i.e. cpm2_clk_setup ?
Next, I'm sure my device tree needs work, but my first stab adds i2c onto
the SOC @ 11860 (immr+11860= I2c mode register) and interrupt 1.

[EMAIL PROTECTED] {
device_type = "i2c";
compatible = "fsl-i2c";
reg = <11860 18>;
interrupts = <1 3>;
interrupt-parent = <&PIC>;
};
After Cleaning up these routines and descriptions, would I be expected to
continue using the /dev/i2c- entries?
