I'm not sure that I really understand what all the fuss is about.
As I understand things the convention that prevails for
MSTP clocks under mach-shmobile is as follows:
1. Clocks not registered by CLKDEV_ICK_ID() are grouped together
under /* MSTP */ followed by:
2. Clocks registered using CLKDEV_ICK_ID() are grouped together
under /* ICK */
I am unsure of the historical reason for this but it does
seem to be consistent.
