Adding i2c read/write support in Little Kernel


Hi All,

I am using little kernel in 410.

I have a requirement of reading and writing on I2C Expander (on i2c bus no. 3) in little Kernel.

It has default support of initialization, reading and writing for I2C-0 interface.

Now I want to in do initialization for I2C-3 interface.

Pinmuxing and other basic stuff had implemented. But I am finding some solution to enable clock for this i2c-3 controller clock.

I need pll configuration for enabling clock for this i2c-3 controller.

Can any body please guide me with some pointer to make it done.
