46 May be 0 for disabling the ramp delay on BUCK{1,2,3,4}.

48 In the absence of the regulator-ramp-delay property, the default ramp
49 delay will be used.

51 Note: Some bucks share the ramp rate setting i.e. same ramp value
52 will be set for a particular group of bucks so provide the same
53 regulator-ramp-delay value for them.
54 Groups sharing ramp rate:
55 * buck{1,6},
56 * buck{2,4},
57 * buck{8,9,10}.
