If we request a GPIO hog, then gpiochip_add_data will attempt
to request some of its own GPIOs. The driver also uses
gpiochip_generic_request which means that for any GPIO request to
succeed the pinctrl needs to be registered. Currently however the
driver registers the GPIO and then the pinctrl mea

Hi Elaine,
in general, I expect some sort of explanation in the commit message on
why clocks need to be always on and cannot be handled from a driver.
Also you can save flags, if you just make leave-clocks critical, which also
is way safer than using clk_ignore_unused - see rk3399.

This is a simple kernel API to query the bypass state of a regulator.

Enabling bypass mode makes a regulator passthrough the supply voltage
directly. It is possible that the supply voltage is set high enough that
it violates machine constraints so let's check for that.
The supply voltage might be higher because of min_dropout_uV or maybe
there is just an unrelated c

If there are any errors in getting the cpu0 regulators, the driver returns

If the cpufreq driver tries to modify voltage/freq during suspend/resume

To avoid this scenario we just increase cpufreq to highest setpoint

The on-stack resource-window 'win' in setup_res() is not
properly initialized. This causes the pointers in the
embedded 'struct resource' to contain stale pointers.
These pointers (in my case the ->child pointer) gets later
propagated to the global iomem_resources list, causin

The function acpi_bus_attach() creates platform_devices if
this is specified by the firmware. But in acpi_bus_trim()
these devices are not removed, leaving a dangling reference

Hi,
here are fixes for three issues I found in ACPI code during
hotplug testing. Patches 2 and 3 fix the same issue, but I
think both make sense on their own.
Please review.
Thanks,
