Bug#1000219: linux-image-rpi: Option SERIAL_SC16IS7XX is currently not enabled
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
