config TEST_ALL_BITRATES
	bool "Test all CAN in Automation (CiA) recommended bitrates"
	help
	  Enable test of all bitrates recommended by CAN in Automation (CiA). Not all CAN
	  controllers can meet all of the bitrates listed below, and some board configurations may
	  impose limits on which bitrates can be met due to limitations in the CAN core clock
	  frequency selection.

	  CiA 301 lists the following nominal bitrates as recommended:
	  - 10 kbit/s
	  - 20 kbit/s
	  - 50 kbit/s
	  - 125 kbit/s
	  - 250 kbit/s
	  - 500 kbit/s
	  - 800 kbit/s
	  - 1 Mbit/s

	  CiA 601-2 lists the following exemplary CAN FD data phase bitrates:
	  - 1.0 Mbit/s
	  - 2.0 Mbit/s
	  - 4.0 Mbit/s
	  - 5.0 Mbit/s
	  - 8.0 Mbit/s

	  CiA 601-3 recommends the following CAN FD core clock frequencies for good node
	  interoperability. The higher the frequency, the better:
	  - 20 MHz
	  - 40 MHz
	  - 80 MHz

	  If this option is not enabled, the tests will be limited to a historical, safe set of CAN
	  bitrates.
