Subject: [PATCH 0/7] media: i2c: dw9719: add DT compatible and DW9718S
 support

The DW9718S voice coil motor is found on various smartphones like
motorola-nora that are currently being worked on in the postmarketOS
community. Since the way it operates is very similar to DW9719, this
patch series adds support for it to the existing dw9719 driver. Because
that driver did not yet support DT, we also add DT bindings and the
dongwoon,dw9719 ofw compatible. With DW9718S, the driver was
tested fully, including runtime PM.

This is a follow-up of [1] and [2].

Changes compared to previous submission:
* Deprecate dongwoon,vcm-freq in favor of dongwoon,vcm-prescale
* Instead of per-device config struct use model ID to handle cases
