Mauro Carvalho Chehab d6697288d8 media: atomisp: Prepare sensor support for ACPI PM 
Add support code for this driver to use ACPI power management.

Yet, at least with known devices, this won't work without
further changes.

The rationale is that the ACPI handling code checks for the _PR? tables
in order to know what is required to switch the device from power state
D0 (_PR0) up to D3COLD (_PR3).

The adev->flags.power_manageable is set to true if the device has a _PR0
table, which can be checked by calling acpi_device_power_manageable(adev).

However, this only says that the device can be set to power off mode.

At least on the DSDT tables we've seen so far, there's no _PR3 nor _PS3
(which would have a somewhat similar effect).

So, using ACPI for power management won't work, except if adding
an ACPI override logic somewhere.
