Subject: [PATCH] can: flexcan: switch the i.MX series to timestamp based rx-offload
As explained by commit b3cf53e988ce ("can: flexcan: add support for
timestamp based rx-offload"), the controller has 64 message buffers but
it uses only 6 for reception. Enabling timestamp mode, instead of FIFO,
allows you to use the maximum number of messages for reception.
