[PATCH 01/10] Add a common struct clk

Hi Rob,

I think you will find many examples in the kernel where that is not done 
by drivers.

Drivers should be checking the return value of clk_get - if they don't,
it's a bug. This is the logical place to check, rather than before all
clock API calls.

For cases where there is no clock provided for the device (but is a
valid clock on some machines), the platform code should return a no-op
clock from the clk_get call. This 'noop clock' would be a good contender
for inclusion into the kernel-wide infrastructure, like clk_fixed.

Cheers,


Jeremy
