[PATCH RFC 2/3] ARM: dts: omap4 clock data

Tue Jun 4 02:39:17 EDT 2013


This is a first pass at creating a unique node for each clock in the
OMAP4 power, reset and & clock manager (PRCM).  So far I have only
converted mux clocks & fixed-rate clocks, which coexist with the current
clock data in the kernel.  The rest needs to be done but better to
publish early and often to see what others think of this approach.
