I would probably wait for control module to become syscon and probably
model this as syscon clk - I thin we should be seeing a series
sometime soon.
Yeah, I will be posting a series in a bit, just running some final tests
on it.
I did the above with Tero's series. Adding the DES HDCP clock works ok.

However, I'm not able to do this in HWMOD framework. To enable the DSS
IP block I need to enable both the DSS func clock and the DES HDCP
clock, but the HWMOD framework only allows one mainclock.

I added the HDCP clock as an opt clock, but those are not enabled
intially by the HWMOD framework, and the call in omap_hwmod.c:_enable()
to soc_ops.wait_target_ready(oh) calls fails.

So... Any ideas how to proceed?
Add the clock enable at the end of dra7xx_dt_clk_init()?

You need to disable the clock at some point though.
