commit 9a633a2bced158c57b73cf4d8e87be60473de1d2 upstream.

commit 40b1936e (regulator: Introduce TI Adaptive Body Bias(ABB) on-chip
LDO driver) missed a pair of brackets which cause the wrong vset data to be
picked up from efuse, resulting in bad VBB voltage values.

As documented in Application Note SWPA117 v2.1(NDA), LDO override has a
requirement that when switching from Bias active + override active
mode(FBB/RBB) to Bypass(nominal) mode, LDO reset must be performed
*after* LDO transitions to Bypass(nominal) mode.

The same rule in reverse applies when switching from a ABB bypass mode
to ABB enabled - LDO override *must* be performed prior to transition to
required ABB mode, if we do not do that, the same glitch takes place.

Currently while transitioning to ABB bypass, we reset the LDO overide
prior to the transition which causes a few milliseconds where ABB LDO
voltage could go all the way to 800mV(based on SoC process node),
during this period, the delta voltage between VDD rail and VBB rail
could cause the system to improperly function.

Fix the linear range settings in commit 5ff26a14c3331
"regulator: wm831x-ldo: Convert to use linear ranges".

For wm831x_gp_ldo:
We have below equations for list voltage before converting to linear ranges:

sel <= 0xe:
        volt = 0.9-1.6V in 50mV steps
sel <= 0x1f:
        volt = 1.7-3.3V in 100mV steps

max_uV for the first linear range should be 1600000 rather than 1650000. Fix it.

For wm831x_aldo:
We have below equations for list voltage before converting to linear ranges:

sel <= 0xc:
        volt = 1-1.6V in 50mV steps
sel <= 0x1f
        volt = 1.7-3.5V in 100mV steps

max_uV for the first linear range should be 1600000 rather than 1650000. Fix it.
