[v2,0/4] media: hi556: Add reset / clk / regulator support

Hi All,

Here is v2 of my patch-series to make the hi556 driver work on x86_64
devices where the power-up / down sequence is not fully handled in ACPI
(as is done on chromebooks) but where instead the driver is expected
to do it itself.

Changes in v2:
- Parse endpoint immediately after getting it and then immediately call
  fwnode_handle_put(ep) to avoid leaking the endpoint fwnode on errors

This has been successfully tested on a "HP Spectre x360 13.5 (2023)":
https://github.com/intel/ipu6-drivers/issues/202

Regards,

Hans
