Subject: I2C: ds1337 - fix 12/24 hour mode bug
Message-ID: <[EMAIL PROTECTED]>
From: Ladislav Michl <[EMAIL PROTECTED]>
DS1339 manual, page 6, chapter Date and time operation:
The DS1339 can be run in either 12-hour or 24-hour mode. Bit 6 of the
hours register is defined as the 12-hour or 24-hour mode-select bit.
When high, the 12-hour mode is selected.
Patch below makes ds1337 driver work as documented in manual.
