Subject: can: flexcan: Add check for transceiver maximum bitrate limitation
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=ee97302d78654eebc1decc80d70c6a7de0217545;p=linux.git

can: flexcan: Add check for transceiver maximum bitrate limitation

CAN FD can transmit up to 8Mbps, but some transceivers only can support
5Mbps, so add check in driver.
