From 9615a29932e8a2c719142ac81481ad7d0e271924 Mon Sep 17 00:00:00 2001 From: Milo Kim Date: Tue, 25 Aug 2015 15:07:08 +0900 Subject: [PATCH] power:lp8727_charger: parsing child node after getting debounce-ms According to lp8727 bindings[*], charging parameter is optional. So parsing can be skipped in case those properties are undefined. However, 'debounce-ms' should be read prior to checking the properties. Otherwise, 'debounce-ms' property will be ignored even it is configured inside the DT. So, counting child is processed after updating 'debounce-ms'.
