From e2da3aaa4254d9e79d9524190fc7e5f0cbdc3c33 Mon Sep 17 00:00:00 2001 From: Sekhar Nori Date: Mon, 16 Nov 2009 17:21:36 +0530 Subject: [PATCH] davinci: make it possible to include clock.h and psc.h in assembly code psc.h contains register defines for PSC module which need to be accessed in assembly code which helps the DA850/OMAP-L138 SoC go to sleep. Shutting down DDR clock using PSC is a part of the sleep procedure. Also, the PLL related hardware definitions in clock.h are needed in assembly code to bypass the DDR2 PLL.
