SubjectRE: [PATCH v2] Input: Bug 18122 - Support Lenovo S10-3t's 2-button ClickPad
Date
I do not have a S10-3t.  I have a HP DV7t with a standard 1 button Clickpad.
I am sorry for any confusion.

I think that 2 different Clickpads will need to be defined: 1 button
Clickpads and 2 button Clickpads. Maybe like this?

#define SYN_CAP_CLICKPAD1BTN(ex0c) ((ex0c) & 0x100000)
#define SYN_CAP_CLICKPAD2BTN(ex0c) ((ex0c) & 0x000100)

So the only exception is the one reported by tob. These are the bits
I've collected:

Yan's S10-3t: model: 1, fw: 7.4, id: 0x1e0b1, caps:
0xd04771/0xa40000/0x4a0500 (2 button clickpad)
tob's S10-3t: model: 1, fw: 7.4, id: 0x1e0b1, caps:
0xd04771/0xe40000/0x5a0400 (?)
hp Envy 14/mini210:
model: 1, fw: 7.4, id: 0x1e0b1, caps:
0xd04771/0xe40000/0x5a0400 (1 button clickpad)

I asked tob to double-check his model and whether his touchpad emits
BTN_MIDDLE or not but get no reply yet. I've checked 4 S10-3t
purchased at different dates and all of them show same exc0 cap, but I
have to say other models selling in other parts of the world may be
still different.
