Subject: [PATCH v2 00/13] Update imx678 to act as a common Sony Starvis 2 driver.
Date: Tue, 13 Oct 2026 16:16:59 +0100	[thread overview]
Message-ID: <20261013-media-starvis2-v2-0-3670722d250a@raspberrypi.com> (raw)

The IMX678 (8MPix) driver has already been accepted into the
kernel.

Whilst preparing a patchset for IMX662 (1080p), I observed such
commonality between the two that it seemed sensible to attempt
a common driver rather than submitting a separate IMX662 series
again.

On checking my box of sensors, I found I had an IMX675 (5MPix) as
well, so that has been incorporated. Subsequently I was able to
add IMX585 (8MPix) and IMX832 (1080p).

The Sony datasheets are rather lacking on the limits for HMAX.
They list HMAX (and VMAX) values for nice round framerates at
a number of the supported link frequencies.
These limits have been adopted for IMX662 and IMX832, but for
IMX675 and IMX585 they have been determined empirically by
observing values of HMAX that start to introduce image issues.

Now cleaned up over the RFC V1.

Changes in v2:
- Switched from an RFC to a patch set.
- Add the dtbinding changes.
- Added IMX832 and IMX585. Tested and fully working on all 5 modules.
- Updated 2 lane handling so that the higher link frequencies achieve
  the maximum frame rates.
- Adds a patch that corrects the minimum exposure time.
- Allow userspace selection of all link frequencies specified via DT
  (makes testing all the link frequency options far easier).
- Link to v1: https://lore.kernel.org/r/20260805-media-starvis2-v1-0-91e8e4eae44f@raspberrypi.com
