Hi All, We are working on Power management on OMAP3 (3530) and I am trying to disable CLKEN and HFCLKOUT through TWL4030 power scripts. However we have not been able to achieve this.
Following are the changes and tests done so far. - VAUX1, CLKEN and HFCLKOUT were assigned to P1 group. - Wrote Singular messages to turn on/off these signals in TWL4030 scripts. - We observed that VAUX1 is able to switch ON/OFF properly as per the script but HFCLKOUT and CLKEN are not behaving as expected. - However if we try writing CLKEN_DEV_GRP to zero, CLKEN is going low. - We have made sure that SYS_OFF_MODE and CLK_REQ signals go low during the system OFF mode, LVL_WAKEUP bit enabled in Px_SW_EVENTS, and STS_CHG bit in STS_HW_CONDITIONS is zero. Is there anything that I am missing? Kindly let me know. Part number of TPS used in our board is TPS65950 BZXNR with regards, - Nagendra. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
