Support for old NVMEM fixed cells was deprecated in favour of "fixed-layout". It's still part of the nvmem.yaml though and may be unknowingly used by new bindings added without much of analyze. To make it more difficult to accidentally support old syntax move its binding to separated file with "deprecated" in its name.

2023-08-16dt-bindings: rtc: isl12022: add bindings for battery alarm trip levelsRasmus Villemoes1-0/+9
The isl12022 has a built-in support for monitoring the voltage of the backup battery, and setting bits in the status register when that voltage drops below two predetermined levels (usually 85% and 75% of the nominal voltage). However, since it can operate at wide range of battery voltages (2.5V - 5.5V), one must configure those trip levels according to which battery is used on a given board. Add bindings for defining these two trip levels. While the register and bit names suggest that they should correspond to 85% and 75% of the nominal battery voltage, the data sheet also says There are total of 7 levels that could be selected for the first alarm. Any of the of levels could be selected as the first alarm with no reference as to nominal Battery voltage level. Hence this provides the hardware designer the ability to choose values based on the discharge characteristics of the battery chosen for the given product, rather than just having one battery-microvolt property and having the driver choose levels close to 0.85/0.75 times that.
