I agree, but so far all the handling for clks/gpios for IPU3 (+ IPU4 (*))
laptops is done in the drivers/platform/x86/intel/int3472 code and the
passing of platform_data with regulator init-data would also happen in
the mfd-cell instantiation code living there. IOW if we just go with
that then we will already have everything in one place. At least
for the IPU3 case.
Regards,
Hans
*) IPU4 also used the INT3472 ACPI devices and what we have for discrete
IO devices seems to match.
