Hi,
Original thread (v1): http://marc.info/?t=140380766500004&r=1&w=2
This series is based on: git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git
branch: topic/palmas (4c0c9ca Merge remote-tracking branch 'regulator/fix/palmas' into regulator-palmas)
This series does a few cleanups to help ensure we dont make typo mistakes and finally provides a fix as attempted by (v1).
Basic cpufreq tests performed on OMAP5uEVM, DRA7-evm, DRA72-evm all of which are palmas variants.
The patches are also available here: https://github.com/nmenon/linux-2.6-playground/commits/broonie-topic-palmas-fixes

Palmas regulator needs to full up the regulator_desc based on PMIC and
type of regulator. However, we dont need to do desc[id] every time. we
can simplify by using a pointer to desc[id] and filling up the
parameters.

We use regmap regulator ops to enable/disable and check if regulator
is enabled for various SMPS. However, these depend on valid
enable_reg, enable_mask and enable_value in regulator descriptor.
So, similar to fix we did in commit 318dbb02b50c
("regulator: palmas: Fix SMPS enable/disable/is_enabled"), populate the
same for TPS65917 SMPS registration. LDO definitions are already in
place.
Fixes: d6f83370ed97 ("regulator: palmas: Add tps65917 PMIC support")

reg_info is a generic term which might cause conflict at a later point
in time. To prevent such a thing from occuring in future, rename to
palmas_reg_info.

Palmas register information is part of the ddata pointer which is used
through out the code by indexing off the driver data array. Instead,
just do the indexing once and use the pointer to further reference
structure fields.
This simplifies code and prevents errors by accessing wrong variables.

With commit d6f83370ed978d5570b7c8c22988310cb9376202 (regulator: palmas:
Add tps65917 PMIC support) palmas_regs_info naming is confusing as it is
a driver data parameter and a local variable. To prevent mistaken
updates, rename the local variable to palmas_generic_regs_info.
