The clickpad flags are in cap[0]:4 and cap[1]:0 bits. + +When the device is detected, the driver now reports only the left +button as the supported buttons so that X11 driver can detect that +the device is Clickpad. A Clickpad device gives the button events +only as the middle button. The kernel driver morphs to the left +button. The real handling of Clickpad is done rather in X driver +side. + +Signed-off-by: Takashi Iwai +Signed-off-by: Dmitry Torokhov +Acked-by: Jian-feng Ding +--- + drivers/input/mouse/synaptics.c | 35 ++++++++++++++++++++++++++++++----- + drivers/input/mouse/synaptics.h | 4 ++++ + 2 files changed, 34 insertions(+), 5 deletions(-) + +diff --git a/drivers/input/mouse/synaptics.c b/drivers/input/mouse/synaptics.c +index d3f5243..9ab9ff0 100644 +--- a/drivers/input/mouse/synaptics.c ++++ b/drivers/input/mouse/synaptics.c +@@ -136,7 +136,8 @@ static int synaptics_capability(struct psmouse *psmouse) + if (synaptics_send_cmd(psmouse, SYN_QUE_CAPABILITIES, cap)) + return -1; + priv->capabilities = (cap[0] << 16) | (cap[1] << 8) | cap[2]; +- priv->ext_cap = 0; ++ priv->ext_cap = priv->ext_cap_0c = 0; ++ + if (!SYN_CAP_VALID(priv->capabilities)) + return -1; + +@@ -149,7 +150,7 @@ static int synaptics_capability(struct psmouse *psmouse) + if (SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 1) { + if (synaptics_send_cmd(psmouse, SYN_QUE_EXT_CAPAB, cap)) { + printk(KERN_ERR "Synaptics claims to have extended capabilities," +- " but I'm not able to read them."); ++ " but I'm not able to read them.\n"); + } else { + priv->ext_cap = (cap[0] << 16) | (cap[1] << 8) | cap[2]; + +@@ -161,6 +162,16 @@ static int synaptics_capability(struct psmouse *psmouse) + priv->ext_cap &= 0xff0fff; + } + } ++ ++ if (SYN_EXT_CAP_REQUESTS(priv->capabilities) >= 4) { ++ if (synaptics_send_cmd(psmouse, SYN_QUE_EXT_CAPAB_0C, cap)) { ++ printk(KERN_ERR "Synaptics claims to have extended capability 0x0c," ++ " but I'm not able to read it.\n"); ++ } else { ++ priv->ext_cap_0c = (cap[0] << 16) | (cap[1] << 8) | cap[2]; ++ } ++ } ++ + return 0; + } + +@@ -347,7 +358,15 @@ static void synaptics_parse_hw_state(unsigned char buf[], struct synaptics_data + hw->left = (buf[0] & 0x01) ? 1 : 0; + hw->right = (buf[0] & 0x02) ? 1 : 0; + +- if (SYN_CAP_MIDDLE_BUTTON(priv->capabilities)) { ++ if (SYN_CAP_CLICKPAD(priv->ext_cap_0c)) { ++ /* ++ * Clickpad's button is transmitted as middle button, ++ * however, since it is primary button, we will report ++ * it as BTN_LEFT. ++ */ ++ hw->left = ((buf[0] ^ buf[3]) & 0x01) ? 1 : 0; ++ ++ } else if (SYN_CAP_MIDDLE_BUTTON(priv->capabilities)) { + hw->middle = ((buf[0] ^ buf[3]) & 0x01) ? 1 : 0; + if (hw->w == 2) + hw->scroll = (signed char)(buf[1]); +@@ -592,6 +611,12 @@ static void set_input_params(struct input_dev *dev, struct synaptics_data *priv) + + dev->absres[ABS_X] = priv->x_res; + dev->absres[ABS_Y] = priv->y_res; ++ ++ if (SYN_CAP_CLICKPAD(priv->ext_cap_0c)) { ++ /* Clickpads report only left button */ ++ __clear_bit(BTN_RIGHT, dev->keybit); ++ __clear_bit(BTN_MIDDLE, dev->keybit); ++ } + } + + static void synaptics_disconnect(struct psmouse *psmouse) +@@ -696,10 +721,10 @@ int synaptics_init(struct psmouse *psmouse) + + priv->pkt_type = SYN_MODEL_NEWABS(priv->model_id) ?
