From 6a06fa6863f190a0ed72f273a2ae5fedc89973ff Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 8 Dec 2009 16:33:11 -0700 Subject: [PATCH] OMAP clockdomain/powerdomain: optimize out sleepdep code on OMAP24xx OMAP24xx chips don't support software-configurable sleep dependencies. Test early for this so the compiler can redact the entire function body on OMAP24xx.
