Subject: [PATCH] regulator: axp20x: Get rid of AXP20X_xxx_START/END/STEPS defines
The AXP20X_xxx_START/END/STEPS defines make the code hard to read and
very hard to check the linear range settings because it needs to check
the defines one-by-one.
The original code without the defines is very good in readability
as the meaning of each field of REGULATOR_LINEAR_RANGE is clear.
So I suggest to get rid of AXP20X_xxx_START/END/STEPS defines.
