Update the bindings with the new properties used for PMI8998.
Changes from V3:
- Removed the default values.Why?
+- qcom,current-limit-microamp + Usage: optional + Value type: <u32> + Definition: uA; per-string current limit; value from 0 to 30000 with + 2500 uA step. - qcom,current-boost-limit Usage: optional Value type: <u32> Definition: mA; boost current limit. For pm8941: one of: 105, 385, 525, 805, 980, 1260, 1400, - 1680. Default: 805 mA + 1680. For pmi8998: one of: 105, 280, 450, 620, 970, 1150, 1300, - 1500. Default: 970 mA + 1500.
I'd say that optional properties should list default values...?
- qcom,ovp Usage: optional Value type: <u32> Definition: V; Over-voltage protection limit; one of: - 27, 29, 32, 35. default: 29V + 27, 29, 32, 35. This property is supported only for PM8941.
Same here.
+- qcom,ovp-millivolt + Usage: optional + Value type: <u32> + Definition: mV; Over-voltage protection limit; + For pmi8998: one of 18100, 19600, 29600, 31100 + If this property is not specified for PM8941, it + falls back to "qcom,ovp" property. +
"voltage-limit-millivolt"? "ovp" is not really well known acronym. Pavel -- (english) http://www.livejournal.com/~pavelmachek (cesky, pictures) http://atrey.karlin.mff.cuni.cz/~pavel/picture/horses/blog.html
