From c5b736d093217890245a33e9a98fe92d6f3529bf Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Fri, 20 Mar 2009 17:29:01 -0700 Subject: davinci: major rework of clock, PLL, PSC infrastructure This is a significant rework of the low-level clock, PLL and Power Sleep Controller (PSC) implementation for the DaVinci family. The primary goal is to have better modeling if the hardware clocks and features with the aim of DVFS functionality. Highlights: - model PLLs and all PLL-derived clocks - model parent/child relationships of PLLs and clocks - convert to new clkdev layer - view clock frequency and refcount via /proc/davinci_clocks Special thanks to significant contributions and testing by David Brownell.
