[PATCH 1/1] ACPI: property: Replicate DT-aligned u32 properties from DisCo for Imaging

From: Sakari Ailus
Date: Wed Nov 01 2023 - 07:15:39 EST


MIPI DisCo for Imaging defines properties for camera sensors that
functionally align with DT equivalents. Replicate the values of these
properties so no-one else needs to know about these property names.

Properties replicated are:

"mipi-img-clock-frequency" -> "clock-frequency"
"mipi-img-led-max-current" -> "led-max-microamp"
"mipi-img-flash-max-current" -> "flash-max-microamp"
"mipi-img-flash-max-timeout" -> "flash-max-timeout-us"

Hi Rafael,

Could you include this patch in the set? Then I think it's fairly
complete on ACPI framework side.
