Recent commits "iwlwifi: remove power-wasting calls to apm_ops.init()" and "iwlagn: power up device before initializing EEPROM" had the goal of reducing device power consumption from the time the module is loaded until the interface is brought up and the device's power saving mechanisms kick in. The idea is that once the module is loaded there is no need for the device to consume power until the interface is brought up. With the current solution the device is only powered up during EEPROM read, and then so also only if the EEPROM type is OTP. We have found that on certain platforms even non-OTP devices require power to be up during EEPROM read. On these platforms the driver never loads and the system log contains the following: iwlagn 0000:03:00.0: MAC is in deep sleep!. CSR_GP_CNTRL = 0x080403D8 We thus now power up all devices during EEPROM read. Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W. Linville <linville@tuxdriver.com> |
