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.
Just one question to Mike and Tero:
would it be possible to have generic binding for such an external clocks?
We have the palmas clock driver already upstream which handles the 32K clocks
from the PMIC. Palmas class of PMICs can be used with TI/nVidia(/Intel?)
platforms. We use Palmas on omap5-uevm, DRA7-EVM also uses Palmas compatible
PMIC and some nVidia platform also uses this class of devices (and they all
need to have control over the 32K clock(s)).
Other platforms initialize their clocks in different manner, they can
use generic of_clk_init I believe. If they can't use that for some
reason, then they need to implement something similar to this.

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