Hi, After I switch from the i2c-intel-mid.c to i2c-designware-* driver, the i2c controller is blocking the system from entering S3 on Oaktrail. See if any hints here, thanks.
During boot up, it says controller timed out..: [ 9.236134] i2c-designware-pci 0000:09:14.0: controller timed out I don't know the reason yet. and then after boot finished, when I try to put the system to S3 by "echo mem > /sys/power/state", it failed. [ 55.077016] i2c-designware-pci 0000:09:14.0: pci_set_power_state failed [ 55.077060] pci_legacy_suspend(): i2c_dw_pci_suspend+0x0/0x54 returns -5 [ 55.077074] pm_op(): pci_pm_suspend+0x0/0xd0 returns -5 [ 55.077084] PM: Device 0000:09:14.0 failed to suspend async: error -5 Don't know if this happens on other platform or not. Any hints? BTW, I tried both the 10 patches series (V1) and the 13 patches series (V2), neither works. http://www.spinics.net/lists/linux-i2c/index.html#04752 Thanks, Kangkai _______________________________________________ MeeGo-kernel mailing list [email protected] http://lists.meego.com/listinfo/meego-kernel
