[PATCH 3/6] can: rockchip-canfd: enable erratum 6 on RK3588

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner at cherry.de>

Sending extended CAN frames from the RK3588's CAN controller, sometimes
sends standard frames, as explained in the erratum's description:

  can0  00001234   [4]  DE AD BE EF
  can0  00000001   [4]  DE AD BE EF
  can0  000007FF   [4]  DE AD BE EF
  can0  00000800   [4]  DE AD BE EF
  can0  1FFFFFFF   [4]  DE AD BE EF
  can0  12345678   [4]  DE AD BE EF
  can0       234   [4]  DE AD BE EF
  can0  00000001   [4]  DE AD BE EF

Enabling the erratum, introduces the correct behaviour in re-sending the
frame:

  can0  1FFFFFFF   [4]  DE AD BE EF
  can0  12345678   [4]  DE AD BE EF
  can0       234   [4]  DE AD BE EF
  can0  00001234   [4]  DE AD BE EF
  can0  00000001   [4]  DE AD BE EF
