An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in
enabled state by the hwmod framework post the initial setup.
Once a real user of the device (a driver) tries to enable it
at a later point, the hwmod framework throws a WARN() about
the device being already in enabled

Hi all!
The 2011.12 release marks glmark2's 10th major release!
Our OpenGL (ES) 2.0 graphics benchmark, glmark2, has been a central
component of the Linaro Graphics WG since the group's creation, and even
before that, when we still had a "User Platforms" team.
glmark2 has been improving steadily

Is there a portable/generic approach for other drivers that may
want to use arm-cpufreq.c? arm_clk is not normally defined for
my SoC and I don't see an easy way to pull it in.

cpufreq needs cpu clock to change frequency.

The driver support single core and multi core ARM SoCs. For multi core,
it assume all cores share the same clock and voltage.
Changes in v2:
- add volatage change support
- change '_' in property name to '-'
- use initial value to calculate loops_per_jiffy
- fix reading cpu_volts property bug

Why isn't of_clk_get() hidden inside clk_get() ?
