Input: synaptics - adjust threshold for treating position values as negative

2012-10-07T15:39:35+00:00

commit 824efd37415961d38821ecbd9694e213fb2e8b32 upstream. Commit c039450 (Input: synaptics - handle out of bounds values from the hardware) caused any hardware reported values over 7167 to be treated as a wrapped-around negative value. It turns out that some firmware uses the value 8176 to indicate a finger near the edge of the touchpad whose actual position cannot be determined. This value now gets treated as negative, which can cause pointer jumps and broken edge scrolling on these machines. I only know of one touchpad which reports negative values, and this hardware never reports any value lower than -8 (i.e. 8184). Moving the threshold for treating a value as negative up to 8176 should work fine then for any hardware we currently know about, and since we're dealing with unspecified behavior it's probably the best we can do. The special 8176 value is also likely to result in sudden jumps in position, so let's also clamp this to the maximum specified value for the axis.

Input: edt-ft5x06 - return -EFAULT on copy_to_user() error

2012-09-19T23:00:26+00:00

copy_to_user() returns the number of bytes remaining, but we want a negative error code here. Signed-off-by: Axel Lin Signed-off-by: Dmitry Torokhov

Input: sentelic - filter out erratic movement when lifting finger

2012-09-19T21:58:07+00:00

When lifing finger off the surface some versions of touchpad send movement packets with very low coordinates, which cause cursor to jump to the upper left corner of the screen. Let's ignore least significant bits of X and Y coordinates if higher bits are all zeroes and consider finger not touching the pad.

Input: ambakmi - [un]prepare clocks when enabling amd disabling

Clocks must be prepared before enabling and unprepared after disabling. Use appropriate functions to do this in one go. Signed-off-by: Pawel Moll Signed-off-by: Dmitry Torokhov

Input: i8042 - disable mux on Toshiba C850D

2012-09-19T21:55:50+00:00

On Toshiba Satellite C850D, the touchpad and the keyboard might randomly not work at boot. Preventing MUX mode activation solves this issue. Signed-off-by: Anisse Astier Cc: stable@kernel.org Signed-off-by: Dmitry Torokhov

Revert "input: ab8500-ponkey: Create AB8500 domain IRQ mapping"

2012-09-19T17:23:18+00:00

This reverts commit ca3b3faf9bee4dc5df4f10eae2d1e48f7de0a8ad. There was a plan to place ab8500_irq_get_virq() calls in each AB8500 child device prior to requesting an IRQ, but as we're no longer using Device Tree to collect our IRQ numbers, it's actually better to allow the core to do this during device registration time. So the IRQ number we pull from its resource has already been converted to a virtual IRQ. Signed-off-by: Lee Jones Acked-by: Linus Walleij Signed-off-by: Dmitry Torokhov

Merge tag 'v3.6-rc5' into for-linus

2012-09-19T17:21:21+00:00

Sync with mainline so that I can revert an input patch that came in through another subsystem tree.

Input: usbtouchscreen - initialize eGalax devices

2012-09-05T05:17:56+00:00

Certain eGalax devices expose an interface with class HID and protocol None. Some work with usbhid and some work with usbtouchscreen, but there is no easy way to differentiate. Sending an eGalax diagnostic packet seems to kick them all into using the right protocol for usbtouchscreen, so we can continue to bind them all there (as opposed to handing some off to usbhid). This fixes a regression for devices that were claimed by (and worked with) usbhid prior to commit 139ebe8dc80dd74cb2ac9f5603d18fbf5cff049f ("Input: usbtouchscreen - fix eGalax HID ignoring"), which made usbtouchscreen claim them instead. With this patch they will still be claimed by usbtouchscreen, but they will actually report events usbtouchscreen can understand. Note that these devices will be limited to the usbtouchscreen feature set so e.g. dual touch features are not supported. I have the distinct pleasure of needing to support devices of both types and have tested accordingly. Signed-off-by: Forest Bond Signed-off-by: Dmitry Torokhov
