Subject: ARM: S3C64XX: Save/restore S3C64XX_SDMA_SEL on suspend/resume
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=348276f4a37ab98559c8c63cbe2a122b7ff65421;p=linux-beck.git

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.
