Input: elantech - make arrays debounce_packet static, reduces object code size

2017-09-11T21:23:40+00:00

Don't populate the arrays debounce_packet on the stack, instead make
them static.  Makes the object code smaller by over 870 bytes:

Merge branch 'bind_unbind' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core into next

This brings in devm_device_add_group() and friends so that we can create
driver-specific device attributes as managed resources.

Input: elantech - constify attribute_group structures

2017-07-12T21:19:28+00:00

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by  work with const
attribute_group. So mark the non-const structs as const.

Input: elantech - add Fujitsu Lifebook E546/E557 to force crc_enabled

2017-06-07T17:32:10+00:00

The Lifebook E546 and E557 touchpad were also not functioning and
worked after running:

        echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add them to the list of machines that need this workaround.

Merge tag 'v4.12-rc3' into next

2017-05-30T02:54:21+00:00

Sync with mainline to bring in changes in platform drovers dropping
calls to sparse_keymap_free() so that we can remove it for good.

Input: elantech - force relative mode on a certain module

2017-05-12T01:00:32+00:00

One of Elan modules with sample version is 0x74 and hw_version is 0x03 has
a bug in absolute mode implementation, so let it run in default PS/2
relative mode.

Input: elantech - add Fujitsu Lifebook E547 to force crc_enabled

2017-04-18T18:29:24+00:00

Temporary got a Lifebook E547 into my hands and noticed the touchpad
only works after running:

	echo "1" > /sys/devices/platform/i8042/serio2/crc_enabled

Add it to the list of machines that need this workaround.

Input: elantech - add Fujitsu Lifebook E556 to force crc_enabled

Another Lifebook machine that needs the same quirk as other similar
models to make the driver working.

Also let's reorder elantech_dmi_force_crc_enabled list so LIfebook enries
are in alphabetical order.

Input: elantech - force needed quirks on Fujitsu H760

2016-10-04T00:31:57+00:00

Just like Fujitsu CELSIUS H730, the H760 also has an Elantech touchpad with
the same quirks. Without this patch, the touchpad is useless out-of-the-box
as the mouse pointer won't move.

This patch makes the driver aware of both the crc_enabled=1 requirement and
the middle button, making the touchpad fully functional out-of-the-box.
