[libcamera-devel] RFC: Arducam 64 MP (Hawkeye)

[Kieran Bingham]

Hi Sakari, Laurent,

Last night I hooked up the Arducam 64 MP Hawkeye camera [0], to an RPi4,
and added the camera helper for the RaspberryPi IPA to libcamera, and
was able to use the camera directly with dtoverlay=arducam_64mp in the
Raspberry Pi /boot/config.txt using the latest release from Raspberry
Pi.

Raspberry Pi have already added the driver for this camera [1] to their
tree, and I have been given the tuning files from Arducam.

This has allowed me to capture an image with pretty good response to
changing lighting conditions, and colours. [2] ... The AF isn't yet
enabled, so that shot is out of focus a little. (That's for later).

Arducam do not wish to name the sensor used in the module, and have
called it the 'arducam_64mp'. But attempting to upstreaming this with
that name worries me.

Furthermore, we would like to maintain libcamera as supporting cameras
that have 'upstream' drivers (or drivers that are on their way
upstream), so I'm keen to identify how we can upstream the drivers to
create a better experience for users who are currently finding that they
need to run a fork of libcamera to operate the module.

So ultimately - my open question is ... Is it acceptable to have camera
drivers that are named by their 'module/integration' rather than their
sensor?
