Subject: [PATCH 0/2] can: m_can: Add CAN clock generated by UPLLCK support

This patch set is to make M_CAN work on SAMA5D2.

The orignal delay is not enough for M_CAN on SAMA5D2 to syschronize
the two clock domains. Increase the delay time to ensure the value
written to INIT can be read back.

Add CAN clock generated by UPLLCK(480 MHz) support, the implementation
doesn't affect the M_CAN without configuring additional CAN clock and
its generated clock.
