LinuxLists.cc - [PATCH v2 1/3] regulator: s2mpxxx: Move regulator min/step voltages in common place

2014-07-15 11:03:08

Subject: [PATCH v2 1/3] regulator: s2mpxxx: Move regulator min/step voltages in common place

This is a cleanup patch and moves min/step voltages in a common samsung
header file so that they can be used by other s2mpxxx PMIC drivers. Only
few required macros are added currently and others can be added if needed.

Subject: [PATCH v2 3/3] regulator: s2mps11: Optimize the regulator description macro

This patch makes the regulator description macro take minimum and
steps voltage as parameter. In this way many repeated macros can be
removed. Now these macros are repeated only if the the LDO/BUCK ctrl
registers have non-linear positions. The good thing is these ctrl registers
are mostly linear so they are not passed as parameters.

This patch reduces the code size and also allow easy addition of more
s2mpxxx PMIC drivers which differs a lot in minimum/step voltages.
