We need "tbclk" clock data for the functioning of ehrpwm
module. Hence, populating the required clock information

Looks good to me.

Tero, just to be clear, are you planning on batching up OMAPish clock
patches and sending a pull request (once they have been reviewed on the
list)?

No, I haven't been planning on sending a pull-req, as I believe you still want to ack the TI related clock driver patches yourself also. If you want to change the setup I am of course willing to negotiate the terms. :)

Thanks,
