From c94fa15ba2d736af786ac1e56686d41987b1aba0 Mon Sep 17 00:00:00 2001 From: Sekhar Nori Date: Mon, 16 Nov 2009 17:21:35 +0530 Subject: [PATCH] davinci: move PSC register definitions from psc.c to psc.h The motivation behind the change is to use the same definitions in the assembly code responsible for suspending the SoC, a part of which is to clock gate the DDR2 clock. Note that the assembly code cannot invoke the C function meant for this. The main reason being that stack in DDR2 cannot be accessed while DDR2 clock is being clock gated.
