Measurement shows very stable waveform, even where - * PCI activity slows the access to the UART, which trips up other - * versions. - * - For other system, non-integer-microsecond pulse/space lengths, - * done using fixed point binary. So, much more accurate carrier - * frequency. - * - fine tuned transmitter latency, taking advantage of fractional - * microseconds in previous change - * - Fixed bug in the way transmitter latency was accounted for by - * tuning the pulse lengths down - the send_pulse routine ignored - * this overhead as it timed the overall pulse length - so the - * pulse frequency was right but overall pulse length was too - * long. Fixed by accounting for latency on each pulse/space - * iteration. - * - * Steve Davies <steve@daviesfam.org> July 2001 - */ - -#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt - -#include <linux/module.h> -#include <linux/errno.h> -#include <linux/signal.h> -#include <linux/sched.h> -#include <linux/fs.h> -#include <linux/interrupt.h> -#include <linux/ioport.h> -#include <linux/kernel.h> -#include <linux/serial_reg.h> -#include <linux/ktime.h> -#include <linux/string.h> -#include <linux/types.h> -#include <linux/wait.h> -#include <linux/mm.h> -#include <linux/delay.h> -#include <linux/poll.h> -#include <linux/platform_device.h> -#include <linux/gpio.h> -#include <linux/io.h> -#include <linux/irq.h> -#include <linux/fcntl.h> -#include <linux/spinlock.h> - -/* From Intel IXP42X Developer's Manual (#252480-005): */ -/* ftp://download.intel.com/design/network/manuals/25248005.pdf */ -#define UART_IE_IXP42X_UUE 0x40 /* IXP42X UART Unit enable */ -#define UART_IE_IXP42X_RTOIE 0x10 /* IXP42X Receiver Data Timeout int.enable */ - -#include <media/lirc.h> -#include <media/lirc_dev.h> - -#define LIRC_DRIVER_NAME "lirc_serial" - -struct lirc_serial { - int signal_pin; - int signal_pin_change; - u8 on; - u8 off; - long (*send_pulse)(unsigned long length); - void (*send_space)(long length); - int features; - spinlock_t lock; -}; - -#define LIRC_HOMEBREW 0 -#define LIRC_IRDEO 1 -#define LIRC_IRDEO_REMOTE 2 -#define LIRC_ANIMAX 3 -#define LIRC_IGOR 4 -#define LIRC_NSLU2 5 - -/*** module parameters ***/ -static int type; -static int io; -static int irq; -static bool iommap; -static int ioshift; -static bool softcarrier = true; -static bool share_irq; -static int sense = -1; /* -1 = auto, 0 = active high, 1 = active low */ -static bool txsense; /* 0 = active high, 1 = active low */ - -/* forward declarations */ -static long send_pulse_irdeo(unsigned long length); -static long send_pulse_homebrew(unsigned long length); -static void send_space_irdeo(long length); -static void send_space_homebrew(long length); - -static struct lirc_serial hardware[] = { - [LIRC_HOMEBREW] = { - .lock = __SPIN_LOCK_UNLOCKED(hardware[LIRC_HOMEBREW].lock), - .signal_pin = UART_MSR_DCD, - .signal_pin_change = UART_MSR_DDCD, - .on = (UART_MCR_RTS | UART_MCR_OUT2 | UART_MCR_DTR), - .off = (UART_MCR_RTS | UART_MCR_OUT2), - .send_pulse = send_pulse_homebrew, - .send_space = send_space_homebrew, -#ifdef CONFIG_LIRC_SERIAL_TRANSMITTER - .features = (LIRC_CAN_SET_SEND_DUTY_CYCLE | - LIRC_CAN_SET_SEND_CARRIER | - LIRC_CAN_SEND_PULSE | LIRC_CAN_REC_MODE2) -#else - .features = LIRC_CAN_REC_MODE2 -#endif - }, - - [LIRC_IRDEO] = { - .lock = __SPIN_LOCK_UNLOCKED(hardware[LIRC_IRDEO].lock), - .signal_pin = UART_MSR_DSR, - .signal_pin_change = UART_MSR_DDSR, - .on = UART_MCR_OUT2, - .off = (UART_MCR_RTS | UART_MCR_DTR | UART_MCR_OUT2), - .send_pulse = send_pulse_irdeo, - .send_space = send_space_irdeo, - .features = (LIRC_CAN_SET_SEND_DUTY_CYCLE | - LIRC_CAN_SEND_PULSE | LIRC_CAN_REC_MODE2) - }, - - [LIRC_IRDEO_REMOTE] = { - .lock = __SPIN_LOCK_UNLOCKED(hardware[LIRC_IRDEO_REMOTE].lock), - .signal_pin = UART_MSR_DSR, - .signal_pin_change = UART_MSR_DDSR, - .on = (UART_MCR_RTS | UART_MCR_DTR | UART_MCR_OUT2), - .off = (UART_MCR_RTS | UART_MCR_DTR | UART_MCR_OUT2), - .send_pulse = send_pulse_irdeo, - .send_space = send_space_irdeo, - .features = (LIRC_CAN_SET_SEND_DUTY_CYCLE | - LIRC_CAN_SEND_PULSE | LIRC_CAN_REC_MODE2) - }, - - [LIRC_ANIMAX] = { - .lock = __SPIN_LOCK_UNLOCKED(hardware[LIRC_ANIMAX].lock), - .signal_pin = UART_MSR_DCD, - .signal_pin_change = UART_MSR_DDCD, - .on = 0, - .off = (UART_MCR_RTS | UART_MCR_DTR | UART_MCR_OUT2), - .send_pulse = NULL, - .send_space = NULL, - .features = LIRC_CAN_REC_MODE2 - }, - - [LIRC_IGOR] = { - .lock = __SPIN_LOCK_UNLOCKED(hardware[LIRC_IGOR].lock), - .signal_pin = UART_MSR_DSR, - .signal_pin_change = UART_MSR_DDSR, - .on = (UART_MCR_RTS | UART_MCR_OUT2 | UART_MCR_DTR), - .off = (UART_MCR_RTS | UART_MCR_OUT2), - .send_pulse = send_pulse_homebrew, - .send_space = send_space_homebrew, -#ifdef CONFIG_LIRC_SERIAL_TRANSMITTER - .features = (LIRC_CAN_SET_SEND_DUTY_CYCLE | - LIRC_CAN_SET_SEND_CARRIER | - LIRC_CAN_SEND_PULSE | LIRC_CAN_REC_MODE2) -#else - .features = LIRC_CAN_REC_MODE2 -#endif - }, -}; - -#define RS_ISR_PASS_LIMIT 256 - -/* - * A long pulse code from a remote might take up to 300 bytes.
