2008-02-08CRIS v32: Update driver for RTC chip pcf8563.Jesper Nilsson
- Moved all calls to register_chrdev to a function called by module_init. - Added mutex locking. - Added better error handling at start up. - Added BIN_TO_BCD of the month value before it is saved to the RTC. - Corrected the month value returned by pcf8563_readreg. - Cache the voltage low value at driver init so the battery status information does not get 'accidentally' cleared when setting the RTC time. - Removed obsolete CONFIG_ETRAX_RTC_READONLY - Voltage low ioctl():s RTC_VLOW_RD -> RTC_VL_READ, RTC_VLOW_SET -> RTC_VL_CLR

2008-02-08CRIS v10: Setup serial port 2 to avoid accidental TXD pulse on startup.Jesper Nilsson
