In commit e9153311 ("regulator: vctrl-regulator: Avoid deadlock getting and setting the voltage"), all calls to get/set the voltage of the control regulator were switched to unlocked versions to avoid deadlocks. However, the call in the probe path is done without regulator locks held. In this case the locked version should be used. Switch back to the locked regulator_get_voltage() in the probe path to avoid any mishaps. Fixes: e9153311 ("regulator: vctrl-regulator: Avoid deadlock getting and setting the voltage") Signed-off-by:

The helper to send IRQ notification for regulator errors had still old description mentioning calling BUG() as a last resort when error status reading has kept failing for more times than a given threshold. The impementation calling BUG() did never end-up in-tree but was replaced by hopefully more sophisticated handler trying to power-off the system. Fix the documentation to reflect actual behaviour.

Enable regmap cache to reduce i2c transactions and corresponding interrupts if regulator is accessed frequently. Since the register map is small -- there's only one register in sy8824c and sy8824e, there are only two registers in sy20276 and sy20278, so we use a FLAT regmap cache. Signed-off-by:

In addition to the ability of merging some power outputs, this chip has an overdrive mode. BCORE1, BCORE2 and BPRO have this ability, in which case the legal current draw is increased from 2 amps to 2.5 amps (at the expense of a quiescent current increase), and the configurable current limits are doubled. If a current higher than maximum half-current mode is requested, enable overdrive, and scale the current limit down. Symmetrically, scale the current limit up when querying a overdrive-enabled regulator. Signed-off-by:

Merge series "Move Hisilicon 6421v600 SPMI and USB drivers out of staging" from Mauro Carvalho Chehab <mchehab+huawei@kernel.org>: Hi Greg, As promised, that's the version 11, meant to be applied after -rc1. It depends on a regression fix patch merged via the regulator's tree: https://git.kernel.org/pub/scm/linux/kernel/git/broonie/regulator.git/commit/?h=for-5.14&id=5db5dd5be70eaf808d9fd90174b957fc5c2912cb (the dependence is just because of a trivial merge conflict) This series contain the final bits needed for the USB3 bus to work without staging drivers on Hikey 970.

This API hook isn't used anywhere outside of the regulator devres code. This function is needed for the devm_regulator_bulk_register_supply_alias() function on the error path, to cleanup any previously registered supply aliases. This change makes the devm_regulator_unregister_supply_alias() local to the regulator core framework, to avoid it being used in any weird logic. It's also removing the doc-string for devm_regulator_unregister_supply_alias(), since it doesn't need to be documented anymore, as no other external consumer should use it. Signed-off-by:
