Bug#927252: linux-4.19.0-4-arm64: Enable SPI CAN drivers for ARM/AARCH64
Package: src:linux
Version: 4.19.28-2
Severity: wishlist
Tags: patch
Dear Maintainer,
Please consider enabling the SPI-attached CAN bus drivers in the Debian kernel.
They are useful on ARM SoCs with an SPI bus, such as the Raspberry Pi.
The Raspbian kernel package already includes these drivers, and they do no
harm on platforms that don't use them. To load these drivers, a suitable
DeviceTree config is required.
Thank you!
Here's a patch for .config:
