As Rob suggested, use the "mps,switch-frequency-hz" instead of the "mps,switch-frequency" for switch frequency. Fortunately, the switch frequency support isn't released, so we can modify it now without any concern. Signed-off-by:

Merge series "regulator: fix deadlock vs memory reclaim" from Michał Mirosław <mirq-linux@rere.qmqm.pl>: For systems that have eg. eMMC storage using voltage regulator, memory reclaim path might call back into regulator subsystem. This means we have to make sure no allocations happen with a regulator or regulator list locked. After this series I see no more lockdep complaints on my test system, but please review and test further. First four patches move allocations out of locked regions, next three came as a drive-by cleanups. --- v2: fix bug in patch #4 spotted by kernel test robot reworded commit #7 description Michał Mirosław (7): regulator: push allocation in regulator_init_coupling() outside of lock regulator: push allocation in regulator_ena_gpio_request() out of lock regulator: push allocations in create_regulator() outside of lock regulator: push allocation in set_consumer_device_supply() out of lock regulator: plug of_node leak in regulator_register()'s error path regulator: cleanup regulator_ena_gpio_free() regulator: remove superfluous lock in regulator_resolve_coupling() drivers/regulator/core.c | 164 +++++++++++++++++++++------------------ 1 file changed, 87 insertions(+), 77 deletions(-) -- 2.20.1 -

I see it takes about 5us per regulator to grab the lock, check that this regulator isn't going to do anything for suspend, and then release the lock. When that is combined with PMICs that have dozens of regulators we get into a state where we spend a few miliseconds doing a bunch of locking operations synchronously to figure out that there's nothing to do. Let's reorganize the code here a bit so that we don't grab the lock until we're actually going to do something so that suspend is a little faster. Signed-off-by:

Since only regulator_ena_gpio_request() allocates rdev->ena_pin, and it guarantees that same gpiod gets same pin structure, it is enough to compare just the pointers. Also we know there can be only one matching entry on the list. Rework the code take advantage of the facts. Signed-off-by:
