From 7704ac937345d4b502062952657027234aa86a37 Mon Sep 17 00:00:00 2001 From: Benjamin Tissoires Date: Tue, 23 Sep 2014 12:08:08 -0400 Subject: HID: wacom: implement generic HID handling for pen generic devices ISDv4 and v5 are plain HID devices. We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires Acked-by: Jason Gerecke Signed-off-by: Jiri Kosina --- drivers/hid/wacom.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'drivers/hid/wacom.h') diff --git a/drivers/hid/wacom.h b/drivers/hid/wacom.h index 64bc1b296d91..0cc53440543a 100644 --- a/drivers/hid/wacom.h +++ b/drivers/hid/wacom.h @@ -89,6 +89,7 @@ #include #include #include +#include #include #include #include @@ -143,4 +144,9 @@ int wacom_setup_input_capabilities(struct input_dev *input_dev, struct wacom_wac *wacom_wac); int wacom_setup_pad_input_capabilities(struct input_dev *input_dev, struct wacom_wac *wacom_wac); +void wacom_wac_usage_mapping(struct hid_device *hdev, + struct hid_field *field, struct hid_usage *usage); +int wacom_wac_event(struct hid_device *hdev, struct hid_field *field, + struct hid_usage *usage, __s32 value); +void wacom_wac_report(struct hid_device *hdev, struct hid_report *report); #endif -- cgit v1.2.3
