高通8x12 添加 TP和按键

1 .在tp的驱动文件中添加以下代码实现按键功能

3.                  struct kobj_attribute *attr,

43.     if (!ft5x06_virtual_key_properties_kobj || rc)  
44.         pr_err("%s: failed to create board_properties\n", __func__);  
45.

47. }  

static ssize_t
ft5x06_virtual_keys_register(struct kobject *kobj,
			     struct kobj_attribute *attr,
			     char *buf)
{
	return snprintf(buf, 200,
	__stringify(EV_KEY) ":" __stringify(KEY_HOME)  ":120:840:80:60"

}

static struct kobj_attribute ft5x06_virtual_keys_attr = {
	.attr = {
		.name = "virtualkeys.ft5x06_ts",
		.mode = S_IRUGO,
	},
	.show = &ft5x06_virtual_keys_register,
};

static struct attribute *ft5x06_virtual_key_properties_attrs[] = {
	&ft5x06_virtual_keys_attr.attr,
	NULL,
};

static struct attribute_group ft5x06_virtual_key_properties_attr_group = {
	.attrs = ft5x06_virtual_key_properties_attrs,
};

struct kobject *ft5x06_virtual_key_properties_kobj;


static void __init ft5x06_touchpad_setup(void)
{
	int rc;
	ft5x06_virtual_key_properties_kobj =
			kobject_create_and_add("board_properties", NULL);
	

	if (ft5x06_virtual_key_properties_kobj)
		rc = sysfs_create_group(ft5x06_virtual_key_properties_kobj,
				&ft5x06_virtual_key_properties_attr_group);

	if (!ft5x06_virtual_key_properties_kobj || rc)
		pr_err("%s: failed to create board_properties\n", __func__);

	
}

另外需要在-mtp.dtsi文件中配置TP的参数和gen_vkeys
