Dear Wolfram, Though register-set looks identical but features were different. And also manufacturer is different. But still it might be possible that we can reuse ds1307.c with some modification. But if I look at the drivers present in drivers/rtc folder. Most of them looks similar but still there are different drivers for different chips.
Please suggest which way is more preferred: modifying existing drivers(of different manufacturer) or writing new driver.
