From 2a6ba39ad6a277595ef9a0187a44f09e062dd3b2 Mon Sep 17 00:00:00 2001 From: Wolfgang Grandegger Date: Tue, 1 Sep 2009 05:37:33 +0000 Subject: can: sja1000: legacy SJA1000 ISA bus driver This patch adds support for legacy SJA1000 CAN controllers on the ISA or PC-104 bus. The I/O port or memory address and the IRQ number must be specified via module parameters: insmod sja1000_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod sja1000_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 sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Here is a full list of the supported module parameters: port:I/O port number (array of ulong) mem:I/O memory address (array of ulong) indirect:Indirect access via address and data port (array of byte) irq:IRQ number (array of int) clk:External oscillator clock frequency (default=16000000 [16 MHz]) (array of int) cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF]) (array of byte) ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL]) (array of byte) Note: for clk, cdr, ocr, the first argument re-defines the default for all other devices, e.g.: insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \ clk=24000000,24000000 Signed-off-by: Wolfgang Grandegger Tested-by: Oliver Hartkopp Signed-off-by: David S.
