This patch makes sure that the LCD bypass state is preserved during sleep mode. It achieves this by saving the S3C64XX_MODEM_MIFPCON register, which is not handled by any other code currently. --- 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 9756321..58899b0 100644 --- a/arch/arm/mach-s3c64xx/pm.c +++ b/arch/arm/mach-s3c64xx/pm.c @@ -30,6 +30,7 @@ #include #include #include +#include #ifdef CONFIG_S3C_PM_DEBUG_LED_SMDK void s3c_pm_debug_smdkled(u32 set, u32 clear) @@ -88,6 +89,7 @@ static struct sleep_save misc_save[] = { SAVE_ITEM(S3C64XX_MEM1CONSLP), SAVE_ITEM(S3C64XX_SDMA_SEL), + SAVE_ITEM(S3C64XX_MODEM_MIFPCON), }; void s3c_pm_configure_extint(void)
