From 027c71bbae3a6eeff00c11d1b708593a5c790314 Mon Sep 17 00:00:00 2001 From: Petri Gynther Date: Tue, 13 Oct 2015 23:13:55 -0700 Subject: Input: improve autorepeat initialization Add new function input_enable_softrepeat() that allows drivers to initialize their own values for input_dev->rep[REP_DELAY] and input_dev->rep[REP_PERIOD], but also use the software autorepeat functionality from input.c. For example, a HID driver could do: static void xyz_input_configured(struct hid_device *hid, struct hid_input *hidinput) { input_enable_softrepeat(hidinput->input, 400, 100); } static struct hid_driver xyz_driver = { .input_configured = xyz_input_configured, } Signed-off-by: Petri Gynther Signed-off-by: Dmitry Torokhov --- drivers/input/input.c | 25 +++++++++++++++++++------ 1 file changed, 19 insertions(+), 6 deletions(-) (limited to 'drivers/input/input.c') diff --git a/drivers/input/input.c b/drivers/input/input.c index 5391abd28b27..880605959aa6 100644 --- a/drivers/input/input.c +++ b/drivers/input/input.c @@ -2044,6 +2044,23 @@ static void devm_input_device_unregister(struct device *dev, void *res) __input_unregister_device(input); } +/** + * input_enable_softrepeat - enable software autorepeat + * @dev: input device + * @delay: repeat delay + * @period: repeat period + * + * Enable software autorepeat on the input device. + */ +void input_enable_softrepeat(struct input_dev *dev, int delay, int period) +{ + dev->timer.data = (unsigned long) dev; + dev->timer.function = input_repeat_key; + dev->rep[REP_DELAY] = delay; + dev->rep[REP_PERIOD] = period; +} +EXPORT_SYMBOL(input_enable_softrepeat); + /** * input_register_device - register device with input core * @dev: device to be registered @@ -2108,12 +2125,8 @@ int input_register_device(struct input_dev *dev) * If delay and period are pre-set by the driver, then autorepeating * is handled by the driver itself and we don't do it in input.c. */ - if (!dev->rep[REP_DELAY] && !dev->rep[REP_PERIOD]) { - dev->timer.data = (long) dev; - dev->timer.function = input_repeat_key; - dev->rep[REP_DELAY] = 250; - dev->rep[REP_PERIOD] = 33; - } + if (!dev->rep[REP_DELAY] && !dev->rep[REP_PERIOD]) + input_enable_softrepeat(dev, 250, 33); if (!dev->getkeycode) dev->getkeycode = input_default_getkeycode; -- cgit v1.2.3-59-g8ed1b
