From: Santosh Shilimkar <santosh.shilimkar@xxxxxx> On OMAP4, there is an issue when L3INIT transitions to OFF mode without device OFF. The SAR restore mechanism will not get triggered without wakeup from device OFF and hence the USB host and USB TLL context will not be restored. Hardware team recommended to remove the OFF state support for L3INIT_PD since there is no power impact. It will be removed on next OMAP revision (OMAP4440 and beyond). Hence this patch removed the OFF state from L3INIT_PD. The deepest state supported on L3INIT_PD is OSWR just like CORE_PD and PER_PD Signed-off-by: Santosh Shilimkar <santosh.shilimkar@xxxxxx> [b-cousson@xxxxxx: update the changelog with next OMAP info] Signed-off-by: Benoit Cousson <b-cousson@xxxxxx> --- arch/arm/mach-omap2/powerdomains44xx_data.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/arch/arm/mach-omap2/powerdomains44xx_data.c b/arch/arm/mach-omap2/powerdomains44xx_data.c index cec9c09..26d7641 100644 --- a/arch/arm/mach-omap2/powerdomains44xx_data.c +++ b/arch/arm/mach-omap2/powerdomains44xx_data.c @@ -267,7 +267,7 @@ static struct powerdomain l3init_44xx_pwrdm = { .prcm_offs = OMAP4430_PRM_L3INIT_INST, .prcm_partition = OMAP4430_PRM_PARTITION, .omap_chip = OMAP_CHIP_INIT(CHIP_IS_OMAP4430), - .pwrsts = PWRSTS_OFF_RET_ON, + .pwrsts = PWRSTS_RET_ON, .pwrsts_logic_ret = PWRSTS_OFF_RET, .banks = 1, .pwrsts_mem_ret = { -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
