From d9e6625c70ff007ae246c9d62f8cdec8d08b2457 Mon Sep 17 00:00:00 2001 From: Benoit Cousson Date: Thu, 20 May 2010 12:31:08 -0600 Subject: OMAP: CM: Move MAX_MODULE_READY_TIME to cm.h The maximum timeout to wait for the PRCM to request that a module exit idle or reach functionnal state is common to OMAP2/3/4 SoCs, so, move it to the chip family-common cm.h include file. Reduce the timeout from 20 ms to 2 ms.
