This time I'm making sure to respond to the right patch :-)

I applied your series on top of latest master and booted it on my
E20C (rk3528-based). It provides me with entries in which I can
read values, like when I applied Jonas' patch on 6.17, so I guess
that it's OK:

  # for i in /sys/devices/platform/soc/*/rockchip-otp0/cells/*; do echo ${i##*/}:;hexdump $i;done
