Input: joydev - fix JSIOCSAXMAP ioctl

2011-01-06T23:08:09+00:00

commit d2520a426dc3033c00077e923a553fc6c98c7564 upstream.

Fixed JSIOCSAXMAP ioctl to update absmap, the map from hardware axis to
event axis in addition to abspam.  This fixes a regression introduced
by 999b874f.

Input: i8042 - fix device removal on unload

2011-01-06T23:07:47+00:00

commit af045b86662f17bf130239a65995c61a34f00a6b upstream.

We need to call platform_device_unregister(i8042_platform_device)
before calling platform_driver_unregister() because i8042_remove()
resets i8042_platform_device to NULL. This leaves the platform device
instance behind and prevents driver reload.

Input: twl40300-keypad - fix handling of "all ground" rows

2010-08-02T17:29:54+00:00

commit 3fea60261e73dbf4a51130d40cafcc8465b0f2c3 upstream.

The Nokia RX51 board code (arch/arm/mach-omap2/board-rx51-peripherals.c)
defines a key map for the matrix keypad keyboard. The hardware seems to
use all of the 8 rows and 8 columns of the keypad, although not all
possible locations are used.

The TWL4030 supports keypads with at most 8 rows and 8 columns. Most keys
are defined with a row and column number between 0 and 7, except

        KEY(0xff, 2, KEY_F9),
        KEY(0xff, 4, KEY_F10),
        KEY(0xff, 5, KEY_F11),

which represent keycodes that should be emitted when entire row is
connected to the ground.  since the driver handles this case as if we
had an extra column in the key matrix. Unfortunately we do not allocate
enough space and end up owerwriting some random memory.

Input: i8042 - add Gigabyte Spring Peak to dmi_noloop_table

2010-08-02T17:29:54+00:00

commit 3e1bbc8d5018a05c0793c8a32b777a1396eb4414 upstream.

Gigabyte "Spring Peak" notebook indicates wrong chassis-type, tripping up
i8042 and breaking the touchpad.  Add this model to i8042_dmi_noloop_table[]
to resolve.

Input: gamecon - reference correct input device in NES mode

2010-08-02T17:29:53+00:00

commit 7b5d3312fbfbb21d2fc7de94e0db66cfdf8b0055 upstream.

We moved input devices from 'struct gc' to individial pads (struct
gc-pad), but gc_nes_process_packet() was still trying to use old
ones and crashing.

Input: ad7877 - keep dma rx buffers in seperate cache lines

2010-05-13T07:43:32+00:00

With dma based spi transmission, data corruption is observed
occasionally. With dma buffers located right next to msg and
xfer fields, cache lines correctly flushed in preparation for
dma usage may be polluted again when writing to fields in the
same cache line.

Make sure cache fields used with dma do not share cache lines
with fields changed during dma handling. As both fields are part
of a struct that is allocated via kzalloc, thus cache aligned,
moving the fields to the 1st position and insert padding for
alignment does the job.

Input: psmouse - reset all types of mice before reconnecting

2010-05-13T07:43:26+00:00

Synaptics hardware requires resetting device after suspend to ram
in order for the device to be operational. The reset lives in
synaptics-specific reconnect handler, but it is not being invoked
if synaptics support is disabled and the device is handled as a
standard PS/2 device (bare or IntelliMouse protocol).

Let's add reset into generic reconnect handler as well.

Input: elantech - use all 3 bytes when checking version

2010-05-13T07:43:19+00:00

Apparently all 3 bytes returned by ETP_FW_VERSION_QUERY are significant
and should be taken into account when matching hardware version/features.
