Example:
@@ -99,4 +146,5 @@ pm8941-wled@d800 {
qcom,switching-freq = <1600>;
qcom,ovp = <29>;
qcom,num-strings = <2>;

Nit. I would assume that specifying qcom,num-strings = <2> implies that
the first 2 strings are used, so one would not also specify
qcom,enabled-strings.
Thanks Bjorn for reviewing the series !
"qcom,enabled-strings" need be specified along with the
"qcom,num-strings".
Because the enabled-strings can be <0, 2> or <0, 3 > also. The driver
picks the string
configuration from the enabled-strings array and enable only those
current-sinks.
(And you should use decimal for natural numbers)
I will modify it in next series.
