| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the flexcan driver uses hardware local echo. This blindly echos all transmitted frames to all receiving sockets, regardless what CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to. This patch now submits transmitted frames to be echoed in the transmit complete interrupt, preserving the reference to the sending socket. This allows the can protocol to correctly handle the local echo. Further this patch moves tx_bytes statistic accounting into the tx_complete handler.

The I/O port or memory address and the IRQ number must be specified via module parameters: insmod cc770_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 for memory mapped ISA devices. Indirect access via address and data port is supported as well: insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Furthermore, the following mode parameter can be defined: clk: External oscillator clock frequency (default=16000000 [16 MHz]) cir: CPU interface register (default=0x40 [DSC]) bcr: Bus configuration register (default=0x40 [CBY]) cor: Clockout register (default=0x00) Note: for clk, cir, bcr and cor, the first argument re-defines the default for all other devices, e.g.: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000 Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Acked-by: Marc Kleine-Budde <mkl@pengutronix.de> Signed-off-by: David S.

The I/O port or memory address and the IRQ number must be specified via module parameters: insmod cc770_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 for memory mapped ISA devices. Indirect access via address and data port is supported as well: insmod cc770_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Furthermore, the following mode parameter can be defined: clk: External oscillator clock frequency (default=16000000 [16 MHz]) cir: CPU interface register (default=0x40 [CPU_DSC]) ocr, Bus configuration register (default=0x00) cor, Clockout register (default=0x00) Note: for clk, cir, bcr and cor, the first argument re-defines the default for all other devices, e.g.: insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod cc770_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000,24000000 Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver is currently not supported on x86_64 systems because the "isa_driver" interface is used (CONFIG_ISA=y). To overcome this limitation, the driver is converted to a platform driver, similar to the serial 8250 driver. Signed-off-by: Wolfgang Grandegger <wg@grandegger.com> Signed-off-by: David S.
