From 55ed96945b1f3d0f4ad21a27b32ce4bd99d8c268 Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 26 Jan 2010 20:12:59 -0700 Subject: OMAP2/3 clkdm/pwrdm: move wkdep/sleepdep handling from pwrdm to clkdm MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Move clockdomain wakeup dependency and sleep dependency data structures from the powerdomain layer to the clockdomain layer, where they belong. These dependencies were originally placed in the powerdomain layer due to unclear documentation; however, it is clear now that these dependencies are between clockdomains. For OMAP2/3, this is not such a big problem, but for OMAP4 this needs to be fixed. Thanks to Benoît Cousson for his advice on this patch.

This patch extends the find_idlest() function in clkops to pass back the idle state indicator for that clock, thus allowing idle state indicators to be defined on a per clock basis if required. This is specifically needed on AM35xx devices as the new IPSS clocks indicates the idle status (0 is idle, 1 is ready) in a way just opposite to how its handled in OMAP3 (0 is ready, 1 is idle).
