From: Hiroshi DOYU <[email protected]> The constraints(opp >= 2) should be set whenever returning from DSP hibernation.
This fixes the problem at the following steps: 1) wait DSP hibernate 2) echo mem > /sys/power/state 3) type key to wakeup Signed-off-by: Hiroshi DOYU <[email protected]> --- drivers/dsp/bridge/wmd/tiomap_sm.c | 16 +++++----------- 1 files changed, 5 insertions(+), 11 deletions(-) diff --git a/drivers/dsp/bridge/wmd/tiomap_sm.c b/drivers/dsp/bridge/wmd/tiomap_sm.c index 02e2675..69f6fb3 100644 --- a/drivers/dsp/bridge/wmd/tiomap_sm.c +++ b/drivers/dsp/bridge/wmd/tiomap_sm.c @@ -98,11 +98,6 @@ DSP_STATUS CHNLSM_DisableInterrupt(struct WMD_DEV_CONTEXT *pDevContext) DSP_STATUS CHNLSM_InterruptDSP2(struct WMD_DEV_CONTEXT *pDevContext, u16 wMbVal) { -#ifdef CONFIG_BRIDGE_DVFS - struct dspbridge_platform_data *pdata = - omap_dspbridge_dev->dev.platform_data; - u32 opplevel = 0; -#endif struct CFG_HOSTRES resources; DSP_STATUS status = DSP_SOK; unsigned long timeout; @@ -116,12 +111,11 @@ DSP_STATUS CHNLSM_InterruptDSP2(struct WMD_DEV_CONTEXT *pDevContext, if (pDevContext->dwBrdState == BRD_DSP_HIBERNATION || pDevContext->dwBrdState == BRD_HIBERNATION) { #ifdef CONFIG_BRIDGE_DVFS - if (pdata->dsp_get_opp) - opplevel = (*pdata->dsp_get_opp)(); - if (opplevel == VDD1_OPP1) { - if (pdata->dsp_set_min_opp) - (*pdata->dsp_set_min_opp)(VDD1_OPP2); - } + struct dspbridge_platform_data *pdata = + omap_dspbridge_dev->dev.platform_data; + + if (pdata->dsp_set_min_opp) + (*pdata->dsp_set_min_opp)(VDD1_OPP2); #endif /* Restart the peripheral clocks */ DSP_PeripheralClocks_Enable(pDevContext, NULL); -- 1.6.2.4 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
