更改的地方总共包括三个文件

arch/arm/mach-pxa/raumfeld.c | 1 +

drivers/input/touchscreen/eeti_ts.c | 8 +++++---

include/linux/input/eeti_ts.h | 1 +

1、raumfeld.c

static struct eeti_ts_platform_data eeti_ts_pdata = {

.irq_active_high = 1,

.gpio = GPIO_TOUCH_IRQ,//添加

};

2、/drivers/input/touchscreen/eeti_ts.c

struct eeti_ts_priv {

struct input_dev *input;

struct work_struct work;

struct mutex mutex;

int irq, irq_active_high;//删除

int irq, gpio, irq_active_high;//添加

};

static inline int eeti_ts_irq_active(struct eeti_ts_priv *priv)

{

return gpio_get_value(irq_to_gpio(priv->irq)) == priv->irq_active_high;//删除

return gpio_get_value(priv->gpio) == priv->irq_active_high;//添加

}

static int __devinit eeti_ts_probe(struct i2c_client *client,

pdata = client->dev.platform_data;

下面两句

==========================================

if (pdata)

priv->irq_active_high = pdata->irq_active_high;

============================================

替换为

==========================================

if (pdata) {

priv->gpio = pdata->gpio;

priv->irq_active_high = pdata->irq_active_high;

}

===============================================

3、/include/linux/input/eeti_ts.h

struct eeti_ts_platform_data {

unsigned int irq_active_high;

unsigned int gpio;//添加

};
