Subject: [PATCH 3/5] ARM: s3c64xx: Save/restore S3C64XX_SDMA_SEL on suspend/resume.
Date: Thu, 21 Jul 2011 14:57:35 +0200 [thread overview]
Message-ID: <mailman.45.1311955585.20020.linux-arm-kernel@lists.infradead.org> (raw)
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.
