Subject: [PATCH v6 0/3] Add i.MX91/93 parallel display support

Hi,

this patchset adds the driver, dt-bindings and dt integration required
to drive a parallel display on the i.MX93.

Since the i.MX91 register layout equals the one from the i.MX93, I added
the support for both but tested only the i.MX93 use-case.

This patchset depends on:
 - https://lore.kernel.org/all/20251201-v6-18-topic-imx93-blkctrl-v1-0-b57a72e60105@pengutronix.de/

@Conor Dooley
I dropped your r-b tag since I added the 'bus-width' property.

Regards,
  Marco

Changelog:
v5:
- https://lore.kernel.org/all/20250304082434.834031-1-victor.liu@nxp.com/

- rebase onto v6.18-rc1
- add review feedback (Alexander)
- driver license "GPL v2" -> "GPL" (checkpatch)
