Yes they are same, l22 is vana l23 is vdig for camera sensor.
riva and rolex is using 2.8v for vana and 1.2v for vdig.
tiare is using 2.85v for vana and 1.2 v for vdig so l22 min-voltage also
should be increased
but l23 max-voltage increase is unnecessary, there is no reason to keep
downstream value there.
Here is some proof
