2014-08-18can: rcar_can: support all input clocksSergei Shtylyov1-6/+36
When writing the driver, I didn't give enough attention to the possible sources of the CAN clock: although the value of the CLKR register was specified by the platform data, the driver only handled one case, that is CAN clock being sourced from the clkp1 clock, the same that clocks the whole CAN module. In order to fix that overlook, we'll have to handle the CAN clock separately from the peripheral clock (however, clkp1 will be specified for a CAN device only once)...
