clock framework: Don't disable a clock already enabled by boot loader?

[dirk.behme@de.bosch.com (Dirk Behme)]

Hi,

we register a clock using clk_register_clkdev() etc already enabled by a 
boot loader. We are doing only the clk_register_clkdev(), but no 
clock_enable() etc on this clock.

With this, enable_count for this clock is zero, while in fact it's 
already on. I.e. the kernel doesn't know that it is on.

This results in

late_initcall(clk_disable_unused())

disabling this clock because the kernel thinks it's unused.

Is this the intended behavior? Is there a way to let the kernel know 
"the clock is enabled already, set enable_count != 0"? Or is the only 
way to do this correctly calling clock_enable() on an already enabled clock?

Many thanks and best regards

Dirk
