i2c: Delete outdated x1205 driver documentation
The x1205 driver moved to the RTC subsystem and was significantly modified since then, so just delete the outdated documentation. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Alessandro Zummo <alessandro.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 is
|
|
||||||
still 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 most
|
|
||||||
other chips just require one and take the second one as the data
|
|
||||||
to be written. To prevent corrupting unknown chips, the user must
|
|
||||||
explicitely set the probe parameter.
|
|
||||||
|
|
||||||
example:
|
|
||||||
|
|
||||||
modprobe x1205 probe=0,0x6f
|
|
||||||
|
|
||||||
The module supports one more option, hctosys, which is used to set the
|
|
||||||
software clock from the x1205. On systems where the x1205 is the
|
|
||||||
only hardware rtc, this parameter could be used to achieve a correct
|
|
||||||
date/time earlier in the system boot sequence.
|
|
||||||
|
|
||||||
example:
|
|
||||||
|
|
||||||
modprobe x1205 probe=0,0x6f hctosys=1
