/* The rk3568 CAN-FD errata sheet as of Tue 07 Nov 2023 11:25:31 +08:00

 * states that only the rk3568v2 is affected by erratum 5, but tests

 * with the rk3568v2 and rk3568v3 show that the RX_FIFO_CNT is

 * sometimes too high. In contrast to the errata sheet mark rk3568v3

 * as effected by erratum 5, too.
