Hi all,
This patch series is an attempt to add support for the third CAN-FD
channel on R-Car V3H2. It consists of three parts:
1. Extend Pin Function Control for the third CAN-FD pin group,
2. Extend the R-Car CAN-FD driver for third CAN-FD channel,
3. Update DTS.
Unfortunately full testing requires local access to a (modified)
Condor-I board:
- CANFD2 can be made available on GP1_19 and GP1_20, which are routed
to test points CP4 and CP5, and to EXIO connector A after populating
two zero-ohm resistors,
- The ADV7511W node must be disabled, as its interrupt pin is shared
with CANFD2_RX,
- An external CAN transceiver must be added.
Alternatively, perhaps some testing can be performed by adding support
for the various test modes (External/Internal Loopback Mode,
Inter-Channel Communication Test) to the CAN-FD driver?
I still have to look into that...
Thanks for your comments!
