The patches were generated from the RPi repo with the following command: git format-patch v6.6.34..rpi-6.1.y Some patches needed rebasing and, as usual, the applied and reverted, wireless drivers, Github workflows, READMEs and defconfigs patches were removed.

Subject: [PATCH 0847/1085] Improvement on backup-switchover-mode overlay value
|
|
definitions (#5884)
|
|
|
|
For the RV3028 RTC, the definitions for its `backup-switchover-mode` overlay
|
|
were not intelligible neither complete/exhaustive.
|
|
|
|
Accordingly to the https://github.com/raspberrypi/linux/issues/2912#issuecomment-477670051
|
|
these one here proposed should be correct.
|
|
|
|
`/boot/config.txt` should be as a configuration example, for rv3028, on a
|
|
Uputronics GPS Extension HAT:
|
|
|
|
# For GPS Expansion Board from Uputronics
|
|
dtparam=i2c_arm=on
|
|
dtoverlay=i2c-rtc,rv3028,backup-switchover-mode=3
|
|
dtoverlay=pps-gpio,gpiopin=18
|
|
init_uart_baud=115200
|
|
|
|
From my tests (`sudo rmmod rtc_rv3028 && sudo i2cget -y 1 0x52 0x37`):
|
|
|
|
`Default from factory`: `0x10`
|
|
`Mode 0`: `0x10`
|
|
`Mode 1`: `0x14`
|
|
`Mode 2`: `0x18`
|
|
`Mode 3`: `0x1c`
|
|
|
|
`Mode 3`: `0x1c` is consistent with the manufacturer configuration script: http://store.uputronics.com/files/configure-rv3028.sh
