Hello, I'm using OMAP3530 with custom board. I have enabled all power mode features as described in PSP wiki, but it still fails to enter any state different from state0. ~ # cat /dbg/pm_debug/count usbhost_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 sgx_pwrdm (OFF),OFF:1,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 per_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 dss_pwrdm (ON),OFF:0,RET:3,INA:4,ON:7,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 cam_pwrdm (RET),OFF:0,RET:1,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 core_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0 neon_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0 mpu_pwrdm (ON),OFF:0,RET:0,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0 iva2_pwrdm (RET),OFF:0,RET:1,INA:0,ON:1,RET-LOGIC-OFF:0,RET-MEMBANK1-OFF:0,RET-MEMBANK2-OFF:0,RET-MEMBANK3-OFF:0,RET-MEMBANK4-OFF:0 per_clkdm->per_pwrdm (11) usbhost_clkdm->usbhost_pwrdm (3) cam_clkdm->cam_pwrdm (0) dss_clkdm->dss_pwrdm (2) core_l4_clkdm->core_pwrdm (12) core_l3_clkdm->core_pwrdm (4) d2d_clkdm->core_pwrdm (0) sgx_clkdm->sgx_pwrdm (0) iva2_clkdm->iva2_pwrdm (0) neon_clkdm->neon_pwrdm (0) mpu_clkdm->mpu_pwrdm (0) prm_clkdm->wkup_pwrdm (0) cm_clkdm->core_pwrdm (0) The next thing was trying to get the uart to sleep (though there might be also problems with other domains ?) . On trying to enable uart as wakeup source I get the following: echo enabled > /sys/devices/platform/omap/omap_uart.2/power/wakeup cat /sys/devices/platform/omap/omap_uart.2/power/wakeup #> disabled (?????) echo 1 > /sys/devices/platform/omap/omap_uart.2/sleep_timeout ~ # [ 85.006622] omap_device: omap_uart.2: new worst case deactivate latency 0: 61035 [ 85.559844] omap_device: omap_uart.2: new worst case activate latency 0: 61035 [ 982.415161] omap_device: omap_uart.2: new worst case deactivate latency 0: 91552 < console hangs here > Thanks for any suggestions, Ran -- 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
