gfdt_get_clock()

Arguments:

node

The FDT offset where the clock node is stored or will be added.

freq

The clock frequency, in Hertz.

Description:

This function gets the phandle for the clock node at the offset specified by node in the FDT. If a clock node doesn't already exist at this offset, the function generates one here. The freq argument sets the clock frequency the guest will see; for example, to set the clock frequency to 32.768 KHz, set freq to 32768.

Returns:

If successful, a phandle for the clock node; otherwise an errno value.
