Functions
struct can_chip *	ctucanfd_initialize (uint32_t addr, rtems_vector_number irq, int ntxbufs, rtems_option irq_option, unsigned long can_clk_rate)
	This function initializes the CTU CAN FD controller.

Detailed Description

This header file contains the implementation of CTU CAN FD controller.

Function Documentation

ctucanfd_initialize()

struct can_chip * ctucanfd_initialize	(	uint32_t	addr,
		rtems_vector_number	irq,
		int	ntxbufs,
		rtems_option	irq_option,
		unsigned long	can_clk_rate
	)

This function initializes the CTU CAN FD controller.

This is an entry point for CTU CAN FD controller initialization. This function allocates generic CAN and CTU CAN FD related structures, sets default values and initializes the resoursec (interrupt handler, semaphore. worker thread).

Parameters

addr	CTU CAN FD code base address.
irq	Interrupt number
ntxbufs	Number of TX hardware buffers
irq_option	RTEMS_INTERRUPT_SHARED or RTEMS_INTERRUPT_UNIQUE
can_clk_rate	CAN clock rate.

Returns

Pointer to CAN chip structure on success, NULL otherwise.
