I'll have to read up on devm_mfd_add_devices; The aux bus was the suggestion 
of Philipp Zabel. At first sight it sounds to me like they do fairly similar 
things. I don't see any precedence for [devm_]mfd_add_devices in drivers/clk/.

Whatever way I go I'd like to use the same for all 3 clock/reset controllers. 
So far I only made topclk a simple-mfd. I recently stumbled upon spinlock 
registers in matrixclk, so I guess I can justify a simple-mfd there too. For 
lspclk all I can see is clocks and resets and I ran out of unknown registers 
in there.
