Kernel driver x1205===================Supported chips:  * Xicor X1205 RTC    Prefix: 'x1205'    Addresses scanned: none    Datasheet: http://www.intersil.com/cda/deviceinfo/0,1477,X1205,00.htmlAuthors:	Karen Spearel <kas11@tampabay.rr.com>,	Alessandro Zummo <a.zummo@towertech.it>Description-----------This module aims to provide complete access to the Xicor X1205 RTC.Recently Xicor has merged with Intersil, but the chip isstill sold under the Xicor brand.This chip is located at address 0x6f and uses a 2-byte register addressing.Two bytes need to be written to read a single register, while mostother chips just require one and take the second one as the datato be written. To prevent corrupting unknown chips, the user mustexplicitely set the probe parameter.example:modprobe x1205 probe=0,0x6fThe module supports one more option, hctosys, which is used to set thesoftware clock from the x1205. On systems where the x1205 is theonly hardware rtc, this parameter could be used to achieve a correctdate/time earlier in the system boot sequence.example:modprobe x1205 probe=0,0x6f hctosys=1
