It is. Without OpRegion, the driver can't power on the camera sensors.

It'd be interesting to know if this is strictly required for the driver
to work properly. The call to intel_soc_pmic_exec_mipi_pmic_seq_element
has some error handling after it, maybe that should just be surrounded
by an #ifdef or IS_ENABLED for PMIC_OPREGION, like some other drivers
do.

Regardless of that:

[PATCH 9/9] staging: media: atomisp: add PMIC_OPREGION dependency

2020-05-29 Thread Arnd Bergmann
Without that driver, there is a link failure in

ERROR: modpost: "intel_soc_pmic_exec_mipi_pmic_seq_element"
[drivers/staging/media/atomisp/pci/atomisp_gmin_platform.ko] undefined!

Add an explicit Kconfig dependency.
