[PATCH 0/2][SRU][J] Add ODM driver rtc-pcf85263

[AceLan Kao]

From: "Chia-Lin Kao (AceLan)" <acelan.kao at canonical.com>

[ Impact ]
rtc-pcf85263 driver is 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/i2c/devices/i2c-1/new_device

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/rtc/rtc1/device/timestamp1

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.
