2019-04-15regulator: max8998: Factor out struct voltage_map_descAxel Lin
The struct voltage_map_desc is used for storing min/max/step fileds, and then setup the min_uV, uV_step and n_voltages fields for regulator_desc. Introduce MAX8998_LINEAR_REG/MAX8998_OTHERS_REG macro to setup these filds directly in regulator_desc to simplify the code.

2019-04-11regulator: mcp16502: Remove setup_regulators functionAxel Lin
It seems a little bit odd current code pass struct regulator_config rather than a pointer to setup_regulators. The setup_regulators is so simple and only has one caller, so remove it. Signed-off-by: Axel Lin <axel.lin@ingics.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2019-04-11regulator: mcp16502: Remove unneeded fields from struct mcp16502Axel Lin
At the context with rdev, we can use rdev->regmap instead of mcp->rmap. The *rdev[NUM_REGULATORS] is not required because current code uses devm_regulator_register() so we don't need to store *rdev for clean up paths.

2019-04-10regulator: anatop: Remove unneeded fields from struct anatop_regulatorAxel Lin
These fields are only used in anatop_regulator_probe() so use local variables instead. The *initdata is not used so can be removed. The *anatop is renamed to *regmap for better readability.

2019-04-08ASoC: ab8500: add range to usleep_rangeNicholas Mc Guire
Providing a range for usleep_range() allows the hrtimer subsystem to coalesce timers - as this delay has no upper limit anyway (interrupts or context switch is possible) it should not hurt to extend this from 2 to 2-4 milliseconds.

The original code separates the selector 25-52 into 2 ranges on purpose because DCDC1/DCDC3 only support up to 1.8V/1.5V in the old code. Both DCDC1 and DCDC3 support up to 3.3V since commit b4c2e158a1e1 ("regulator: tps65217: Allow DCDC1 and DCDC3 up to 3.3V"), so merge 25-30 and 31-52 ranges to one range.
