Package: linux-image-rpi
Version: 5.10.70-1
Severity: wishlist
X-Debbugs-Cc: bernhardu@mailbox.org


Dear Maintainer,
I attempted to use a plain Debian image created with [1]
with a Raspberry Pi Zero WH and with
a "Serial Expansion HAT" via I2C.

Unfortunately it looks like the Debian kernel has the
needed module not enabled [2].

(A Raspbian shows the configuration shown in [3].)


But I am not sure if this would be sufficient already
(at least for multiple of this HATs),
because the manufacturer description leads to
adding some device tree overlays (sc16is752-i2c.dtbo), which seem not
to be contained in the linux-image-rpi package too.

Kind regards,
Bernhard
