This bug is awaiting verification that the linux/5.15.0-94.104 kernel in
-proposed solves the problem. Please test the kernel and update this bug
with the results. If the problem is solved, change the tag
'verification-needed-jammy-linux' to 'verification-done-jammy-linux'. If
the problem still exists, change the tag 'verification-needed-jammy-
linux' to 'verification-failed-jammy-linux'.


If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.


See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  Subject: [PATCH 1/3] Add rtc-pcf85263 kernel driver

  BugLink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2045385

  
  [ 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/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.

  [ Other Info ]
