2012-03-16regulator: Fix up a confusing dev_warn when DT lookup failsRajendra Nayak
of_parse_phandle() returns NULL either if the property name itself does not exist or if it (exists and) does not reference a valid phandle. Giving out a warn like the one below (that the property references an invalid phandle) can be confusing when the property itself does not exist in the node. Fix it with a more sensible message and make it a dev_dbg instead of a dev_warn.

2012-03-14regulator: Refactor tps6507x to use one tps6507x_pmic_ops for all LDOs and DCDCsAxel Lin
All the callback functions implementation for DCDCx and LDOx are very similar, I think it is ok to use one tps6507x_pmic_ops for all LDOs and DCDCs. This refactor removes a couple of duplicated code.
