Urrgh.. this slipped past.. :(

ti,system-power-controller is traditionally used for other PMICs from
TI to indicate that poweroff functionality will be provided by the
PMIC driver. similar approach is taken by Maxim as well.. I know the
commit introducing the binding has been around for long, but
considering that we do not have a single dts using this yet, should we
consider adding "ti,system-power-controller"(as against removing
ti,use_poweroff - so that older down stream dtbs still work) and using
it in the new code?

just proposing here.
