[PATCH 0/2] staging/greybus: Add BeaglePlay Greybus Driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This driver can be used in any Greybus setup where SVC and Linux Host
are connected over UART.

This driver has been tested on BeaglePlay by BeagleBoard.org. It communicates
with BeaglePlay CC1352 co-processor which serves as Greybus SVC. This
replaces the old setup with bcfserial, wpanusb and GBridge. This driver also
contains async HDLC code since communication with SVC take place over UART
using HDLC.

This patchset also introduces a compatible property for the UART that is
connected to CC1352 in BeaglePlay. I am not quite sure if it needs its
own DT Schema file under `Documentation/devicetree/bindings/serial`.

This driver has been created as a part of my Google Summer of Code 2023.
For more information, take a look at my blog.

I have made most of the changes requested in the first version of this
patch and simplified the code as well.

This patchset has been tested over `next-20230825`.
