|
Linux driver did activate RTC registers at start and deactivated them only at shutdown. But as long as the registers are activated, the power consumption is higher. Correct is to activate the registers immediately before reading from or writing to them and to deactivate them immediately after again. |

|
Driver rewritten to handle register activation correctly. |
