From 348276f4a37ab98559c8c63cbe2a122b7ff65421 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Tue, 23 Aug 2011 11:33:08 +0900 Subject: [PATCH] ARM: S3C64XX: Save/restore S3C64XX_SDMA_SEL on suspend/resume This patch makes sure that S3C64XX_SDMA_SEL register is preserved during sleep mode, as it is critical for DMA operation and the DMA driver alone does not provide any power management facilities.
