[PATCH v3 4/5] ipa: raspberrypi: Add tuning file for IMX327 sensor

Sun Nov 24 20:29:49 CET 2024
Add a default tuning file for Sony IMX327 sensor. This tuning file
is a copy of the IMX290 and is added to make the IMX327 sensor
just work without hassle. Note the extra description field to
clarify this is just an interim tuning file untill someone
provides a proper one.
