This follows on the change ("regulator: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in 4.14") but changes regulators didn't exist in Linux 4.19 but did exist in Linux 5.4.

2021-01-07regulator: mcp16502: lpm pin can be optional on some platformsClaudiu Beznea1-1/+1
On some platform (e.g. SAMA7G5) LPM pin should be optional as it can be controlled explicitly (via shutdown controller registers) in the platform specific power saving code to decrease the power consumption while suspended as this SoC pin may be connected to other devices that could take power saving actions based on its value.

2019-04-11regulator: mcp16502: Remove setup_regulators functionAxel Lin1-26/+11
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 Lin1-24/+16
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.

2018-12-14regulator: mcp16502: add support for suspendAndrei.Stefanescu@microchip.com1-0/+34
This patch adds support for entering/resuming suspend states. It does this by setting the LPM pin of the PMIC. When suspending the PMIC will enter the Low-power mode when the LPM pin will be set to high. If the suspend target state is suspend-to-mem, the PMIC will transition to Hibernate mode, otherwise, if it is standby, it will remain in Low-power mode.
