can: cc770: legacy CC770 ISA bus driver
This patch adds support for legacy Bosch CC770 and Intel AN82527 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 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.
