Hi,

This patch adds possibility to register external clocks (outside the main
SoC) on TI boards through device tree. Clock sources as such include for
example twl-6030 / twl-6040 chips and variants which can be used to clock
for example audio / WLAN chips.

This patch can be queued once someone has a use-case + patches that requires
usage of such clocks.
