From 687fe7dfb736b03ab820d172ea5dbfc1ec447135 Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Sun, 23 Jul 2023 22:30:18 -0700 Subject: [PATCH] Input: tca6416-keypad - always expect proper IRQ number in i2c client Remove option having i2c client contain raw gpio number instead of proper IRQ number. There are no users of this facility in mainline and it will allow cleaning up the driver code with regard to wakeup handling, etc. Link: https://lore.kernel.org/r/20230724053024.352054-1-dmitry.torokhov@gmail.com Signed-off-by: Dmitry Torokhov --- drivers/input/keyboard/tca6416-keypad.c | 27 ++++++++++----------------- include/linux/tca6416_keypad.h | 1 - 2 files changed, 10 insertions(+), 18 deletions(-) diff --git a/drivers/input/keyboard/tca6416-keypad.c b/drivers/input/keyboard/tca6416-keypad.c index 2f745ca..01bc0b8 100644 --- a/drivers/input/keyboard/tca6416-keypad.c +++ b/drivers/input/keyboard/tca6416-keypad.c @@ -148,7 +148,7 @@ static int tca6416_keys_open(struct input_dev *dev) if (chip->use_polling) schedule_delayed_work(&chip->dwork, msecs_to_jiffies(100)); else - enable_irq(chip->irqnum); + enable_irq(chip->client->irq); return 0; } @@ -160,7 +160,7 @@ static void tca6416_keys_close(struct input_dev *dev) if (chip->use_polling) cancel_delayed_work_sync(&chip->dwork); else - disable_irq(chip->irqnum); + disable_irq(chip->client->irq); } static int tca6416_setup_registers(struct tca6416_keypad_chip *chip) @@ -266,12 +266,7 @@ static int tca6416_keypad_probe(struct i2c_client *client) goto fail1; if (!chip->use_polling) { - if (pdata->irq_is_gpio) - chip->irqnum = gpio_to_irq(client->irq); - else - chip->irqnum = client->irq; - - error = request_threaded_irq(chip->irqnum, NULL, + error = request_threaded_irq(client->irq, NULL, tca6416_keys_isr, IRQF_TRIGGER_FALLING | IRQF_ONESHOT | IRQF_NO_AUTOEN, @@ -279,7 +274,7 @@ static int tca6416_keypad_probe(struct i2c_client *client) if (error) { dev_dbg(&client->dev, "Unable to claim irq %d; error %d\n", - chip->irqnum, error); + client->irq, error); goto fail1; } } @@ -298,8 +293,8 @@ static int tca6416_keypad_probe(struct i2c_client *client) fail2: if (!chip->use_polling) { - free_irq(chip->irqnum, chip); - enable_irq(chip->irqnum); + free_irq(client->irq, chip); + enable_irq(client->irq); } fail1: input_free_device(input); @@ -312,8 +307,8 @@ static void tca6416_keypad_remove(struct i2c_client *client) struct tca6416_keypad_chip *chip = i2c_get_clientdata(client); if (!chip->use_polling) { - free_irq(chip->irqnum, chip); - enable_irq(chip->irqnum); + free_irq(client->irq, chip); + enable_irq(client->irq); } input_unregister_device(chip->input); @@ -323,10 +318,9 @@ static void tca6416_keypad_remove(struct i2c_client *client) static int tca6416_keypad_suspend(struct device *dev) { struct i2c_client *client = to_i2c_client(dev); - struct tca6416_keypad_chip *chip = i2c_get_clientdata(client); if (device_may_wakeup(dev)) - enable_irq_wake(chip->irqnum); + enable_irq_wake(client->irq); return 0; } @@ -334,10 +328,9 @@ static int tca6416_keypad_suspend(struct device *dev) static int tca6416_keypad_resume(struct device *dev) { struct i2c_client *client = to_i2c_client(dev); - struct tca6416_keypad_chip *chip = i2c_get_clientdata(client); if (device_may_wakeup(dev)) - disable_irq_wake(chip->irqnum); + disable_irq_wake(client->irq); return 0; } diff --git a/include/linux/tca6416_keypad.h b/include/linux/tca6416_keypad.h index b0d36a9..5cf6f6f 100644 --- a/include/linux/tca6416_keypad.h +++ b/include/linux/tca6416_keypad.h @@ -25,7 +25,6 @@ struct tca6416_keys_platform_data { unsigned int rep:1; /* enable input subsystem auto repeat */ uint16_t pinmask; uint16_t invert; - int irq_is_gpio; int use_polling; /* use polling if Interrupt is not connected*/ }; #endif -- 2.7.4
