Subject: [PATCH 1/3] Add rtc-pcf85263 kernel driver
BugLink: https:/
[ Impact ]
rtc-pcf85263 driver needed for ODM partner
[ Test Plan ]
Load the driver setting the timestamp level to 0 (default to 1) :
modprobe rtc-pcf85263 tsl=0
export the rtc device:
echo "pcf85263 0x51" > /sys/bus/
RTC device should act as a standard RTC,
hwclock -r -f /dev/rtc1 #for reading
hwclock -w -f /dev/rtc1 #for writing
This driver has anti-tampering function.
Get the current tamper timestamp:
cat /sys/class/
unmount the bottom metal panel, unscrewing the 6x T-10 screws and let the anti-tampering goes in open state.
The timestamp should be updated to the current time.
[ Where problems could occur ]
Events could occur on the I2C bus communication.
[ Other Info ]

I have no comment on the driver itself, but the commit description should contains your signed-off, and the BugLink should be "BugLink: https:/ /bugs.launchpad .net/bugs/ 2045385"
