as far as I remember there has not been any binding merged that declares
this supply. Thankfully following the double phandle below, the Edge2 is
designed to use the same regulator for the mem-supply, so special handling
isn't even needed.
Indeed, currently there isn't any user in the mainline tree (neither
bindings nor drivers) for this separate regulator. Mainline cpufreq-dt
only expects a single regulator, and as Heiko pointed out Edge2 uses the
same physical regulator to power both the CPU core and its SRAM, so
adding a separate mem-supply here isn't helpful.
Best regards, Alexey
