I'd rather hope the optional clock could be enabled whenever the driver
needs it, between enabling and disabling the hwmod.

Yeah, this is the case most of the time, except for you.

Are you talking only about the DSS_FCLK opt-clock from PRCM, or all DSS
opt clocks (sys clk, hdmi clk, tv clk, dac clock)?

I hope the rest of the opt clocks can be enabled later. Although I guess
all/many of them will be needed during reset, but that should be already
handled by the hwmod fmwk.

Yes, sorry, for the confusion, but the point is that they all look the 
same to me :-)

The PRCM does not make any difference for any of these opt_clock, they 
are all under SW control.

Except that one of them must be enabled because internally it is used as 
a functional clock.
