The atmel driver sets a default resolution of 20 for each touchpads it
creates. On this model, 10 is more appropriate.
The resolution is not set for the touchscreen by the kernel, so match
the name to both touchpad and touchscreen.
(cherry picked from commit 696f1dbfe1)
The Lenovo X230 advertize a vertical resolution of 136, which gives a true
size of 31 mm. The actual physical size of the touchpad is 40 mm, so
override the resolution to 100.

Verified for the 5,1 Macbook, the others are guesses based on the list of
supported devices of the moshi trackpad protector.

Resolution calculated based on the min/max settings set in the kernel driver,
divided by the physical size. This is probably slightly off, but still better
than no resolution at all.

Parse properties in the form
EVDEV_ABS_00="<min>:<max>:<res>:<fuzz>:<flat>"
and apply them to the kernel device. Future processes that open that device
will see the updated EV_ABS range.
This is particularly useful for touchpads that don't provide a resolution in
the kernel driver but can be fixed up through hwdb entries (e.g. bcm5974).
All values in the property are optional, e.g. a string of "::45" is valid to
set the resolution to 45.
The order intentionally orders resolution before fuzz and flat despite it
being the last element in the absinfo struct. The use-case for setting
fuzz/flat is almost non-existent, resolution is probably the most common case
we'll need.
To avoid multiple hwdb invocations for the same device, replace the
hwdb "keyboard:" prefix with "evdev:" and drop the separate 60-keyboard.rules
file. The new 60-evdev.rules is called for all event nodes
anyway, we don't need a separate rules file and second callout to the hwdb
builtin.
(cherry picked from commit 51c0c28698)
Changes to 51c0c28698:
- leave 60-keyboard.rules in place. This forces a double callout to the
keyboard builtin but avoids breaking current setups that rely on the
keyboard: prefix
- drop the AT keyboard matching rule from 60-evdev.rules, this is for keyboard
matches and handled by the 60-keyboard.rules that was restored with the
backport.
Since 3.19, the devices have the proper vid/pid and the model number in the
name.

(cherry picked from commit 39addb81b6)
On these several HP laptops, the microphone mute hotkey is "Fn+F8" and
the scancode for this hotkey is 0x81, but this scancode was mapped to
fn_esc in the HP generic keymap section. To fix this problem, we add
a machine specific keymap section to add the correct keymap rule.

Currently used to tag devices in the new Lenovo *50 series and the X1 Carbon
3rd. These laptops re-introduced the physical trackpoint buttons that were
missing from the *40 series but those buttons are now wired up to the
touchpad.
The touchpad now sends BTN_0, BTN_1 and BTN_2 for the trackpoint. The same
button codes were used in older touchpads that had dedicated scroll up/down
buttons. Input drivers need to work around this and thus know what they're
dealing with.
For the previous gen we introduced INPUT_PROP_TOPBUTTONPAD in the kernel, but
the resulting mess showed that these per-device quirks should really live in
userspace.
The list currently includes the X1 Carbon 3rd PNPID, others will be added as
get to know which PNPID they have.
Some time ago 95-keymap.rules was replaced by
60-keyboard.hwdb. Original comments for MSI laptops (that were in
95-keymap.rules) were removed, but I think they are important for
understanding what's going on.
