2017-09-27regulator: cpcap: Fix standby modeSebastian Reichel1-3/+5
commit 91a024e80336528d12b67b5a2e636b9e4467d3ec upstream. The original patch from Tony uses standby mode bit inverted, which is not correct. This fixes all instances in the driver code for get & set mode. This did not yet make problems, since mode has not been changed by any mainline driver so far.

2017-06-13regulator: core: Prioritise consumer mappings over regulator nameCharles Keepax1-5/+5
Currently, when looking up a regulator supply, the regulator name takes priority over the consumer mappings. As there are a lot of regulator names that are in fairly common use (VDD, MICVDD, etc.) this can easily lead to obtaining the wrong supply, when a system contains two regulators that share a name. The explicit consumer mappings contain much less ambiguity as they specify both a name and a consumer device. As such prioritise those if one exists and only fall back to the regulator name if there are no matching explicit mappings.

2017-06-07regulator: da9061: BUCK and LDO regulator driverSteve Twiss2-14/+293
Regulator support for the DA9061 is added into the DA9062 regulator driver. The regulators for DA9061 differ from those of DA9062. A new DA9061 enumeration list for the LDOs and Bucks supported by this device is added. Regulator information added: the old regulator information for DA9062 is renamed from local_regulator_info[] to local_da9062_regulator_info[] and a new array is added to support local_da9061_regulator_info[]. The probe() function switches on the da9062_compatible_types enumeration and configures the correct da9062_regulator_info array and number of regulator entries. Kconfig is updated to reflect support for DA9061 and DA9062 regulators. Signed-off-by: Steve Twiss <stwiss.opensource@diasemi.com> Signed-off-by: Mark Brown <broonie@kernel.org>

Commit 43530b69d758328d3ffe6ab98fd640463e8e3667 ("regulator: Use regmap_read/write(), regmap_update_bits functions directly") intended to replace working inline helper functions with standard regmap calls. However, it also inverted the set/clear logic of the "CORE ADJ Allowed" bit. That patch was clearly never tested, since without that bit cleared, the core VDCDC1 voltage output does not react to I2C configuration changes. This patch fixes the issue by clearing the bit as in the original, correct implementation. Note for stable back porting that, due to subsequent driver churn, this patch will not apply on every kernel version.
