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. --- arch/arm/mach-s3c64xx/pm.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-) diff --git a/arch/arm/mach-s3c64xx/pm.c b/arch/arm/mach-s3c64xx/pm.c index 799a212..9756321 100644 --- a/arch/arm/mach-s3c64xx/pm.c +++ b/arch/arm/mach-s3c64xx/pm.c @@ -86,6 +86,8 @@ static struct sleep_save misc_save[] = { SAVE_ITEM(S3C64XX_MEM0CONSLP0), SAVE_ITEM(S3C64XX_MEM0CONSLP1), SAVE_ITEM(S3C64XX_MEM1CONSLP), + + SAVE_ITEM(S3C64XX_SDMA_SEL), }; void s3c_pm_configure_extint(void)
