Hi,
Here is a new set of my input patches, would love to hear comments and/or
suggestions. The patches can also be found at:
http://www.geocities.com/dt_or/input/2_6_6-rc2/
bk pull bk://dtor.bkbits.net/input
01-synaptics-cleanup.patch
Adjust the way we extract button data; do not announce BTN_BACK/BTN_FORWARD
unless touchpad has SYN_CAP_FOUR_BUTTON; adjust querying extended
capailities according to the latest Synaptics documentation addendum
02-synaptics-middle-button.patch
Support for touchpads that have middle button.
03-dont-change-max-proto.patch
Do not mangle global parameter when probing for protocol extensions.
04-lkkbd-whitespace.patch
05-lkkbd-simplify.patch
Drop some duplicate checks.
06-atkbd-soften-xfree-warning.patch
Soften accusations against XFree when we get spurios ACK/NAK from the KBC.
07-atkbd-trailing-whitespace.patch
08-atkbd-bitfields.patch
Cleanup, convert some essentialy boolean fields ino bitfields.
09-atkbd-timeout-complaints.patch
Do not complain about surious NAK in cases when keyboard controller's
timeout is bigger then in atkbd and NAK to our probe comes too late.
10-psmouse-rescan-on-hotplug.patch
When we get 0xAA 0x00 froma device do reconnect and not rescan in case
it's an old device that just reset for some reason (KVM switch?)
11-psmouse-reconnect-after-error.patch
Move psmouse_reconnectafter handling from synaptocs to psmouse-base so
it can later be used by other protocols.
12-psmouse-protocol-handler.patch
Add protocol_handler funtion pointer to the psmouse structure so we
won't have unsighly if/switch constructs in psmouse-base when we add
support for more protocols.
13-psmouse-sliced-command.patch
Synaptics and logips2pp noth implemented their own routines of sening
extended PS/2 commands to the mouse; consolidate the code.
14-atkbd-reconnect-probe.patch
Do not alter psmouse structure when probing for supported protocols
at reconnect. Cures an OOPS when Synaptics is not detected at first
(USB legacy emulation problem, etc) but is detected after resume.
15-psaux-config.patch
Allow disabling legacy psaux device even for non-embedded systems;
not everyone wants/needs it.

Input: synaptics driver cleanup
- pack all button data in 2 bytes instead of 48
- adjust the way we extract button data
- query extended capabilities if SYN_EXT_CAP_REQUESTS >= 1
(was == 1) according to Synaptics' addendum to the interfacing
guide
- do not announce or report BTN_BACK/BTN_FORWARD unless touchpad
has SYN_CAP_FOUR_BUTTON in its capability flags

Here we are. Linus, please apply this patch. It incorporated Dmitry's
changes and also updates the lkkbd driver to it's current version (which
I use on my Athlon).
#
# This patch updates the lkkbd driver to it's current version.
# It also incorporates two patches suggested on LKML (fixing
# some leading whitespace and an unneccessary check).

By the way, until the atkbd.c / keyboard.c interaction is fixed, using setkeycodes might
*not* make the keys known *properly*. (example: try setkeycodes e001 129: you'll notice
that a key whose raw code is 0x81 will not produce keycode 129, because the raw mode
emulation will actually turn the 0x81 in a 0x85.)
(See also the temporary patch I posted recently).

I have 2 more:

- make open and close methods optional so drivers are not forced to supply

I think this is incorrect. We cannot set the bits in bitfields
atomically, which we need in some cases. We probably need to add
volatiles to some of them, too.

We may need to protect ourselves against this - it may confuse the probe
in addition to just generating spurious messages.

Hmm.. you were against extending timeout in atkbd_command as it would prolong
probing. It should not interfere with probing as we only kill data when we not
expecting a response to a command.

I don't think we have a problem with concurrent access here... One group is set
exclusively in atkbd_interrupt, other one is pretty mich static.

If you need volatile in the driver, then the driver is probably buggy.
