From cb74f0223fcf9b2db8f57d9ee5fa4738c066f3c6 Mon Sep 17 00:00:00 2001 From: Kevin Hilman Date: Wed, 20 Oct 2010 23:19:03 +0000 Subject: [PATCH] omap: UART: fix wakeup registers for OMAP24xx UART2 On OMAP24xx, UART2 WKEN and WKST registers are in PM_WKEN2_CORE and PM_WKST2_CORE respecitvely. Fix the OMAP2 register init to use the correct registers on OMAP24xx.
