Bosch MCAN controller Device Tree Bindings
Required properties:
- compatible : Should be "bosch,m_can" for M_CAN controllers
- reg : physical base address and size of the M_CAN
registers map and message ram
- interrupts : property with a value describing the interrupt
- clocks : clocks used by controller
- mram-cfg : message ram configuration data, the format is
<offset sidf_elems xidf_elems rxf1_elems rxb_elems txe_elems txb_elems>
The 'offset' is the address offset inside the message ram. This is usually set
if you're using the shared message ram while the other part is used by another
m_can controller.
The left cell are all the number of each elements inside the message ram.
Please refer to 2.4.1 Message RAM Con.guration in Bosch M_CAN user mannual
for each elements definition.
