linux-toradex.git/drivers/input/input.c, branch v3.14.3

Merge branch 'next' into for-linus

2014-01-23T16:10:44+00:00

First round of input updates for 3.14.

Input: allocate absinfo data when setting ABS capability

2013-12-31T18:53:19+00:00

We need to make sure we allocate absinfo data when we are setting one of
EV_ABS/ABS_XXX capabilities, otherwise we may bomb when we try to emit this
event.

Input: don't call input_dev_release_keys() in resume

2013-12-16T10:19:10+00:00

When waking up the platform by pressing a specific key, sending a
release on that key makes it impossible to react on the event in
user-space. This is fixed by moving the input_reset_device() call to
resume instead.

[dmitry.torokhov@gmail.com: make sure we still restore LED/sound state
after resume, handle hibernation properly]

Merge first round of changes for 3.13 merge window.

Input: remove a redundant max() call

2013-10-31T15:46:07+00:00

dev->hint_events_per_packet is guaranteed to be >= packet_size.
so an extra max() call is not needed.

Input: move name/timer init to input_alloc_dev()

2013-10-06T08:23:26+00:00

We want to allow drivers to call input_event() at any time after the
device got allocated. This means input_event() and input_register_device()
must be allowed to run in parallel.

The only conflicting calls in input_register_device() are init_timer() and
dev_set_name(). Both can safely be moved to device allocation and we're
good to go.

Input: document that unregistering managed devices is not necessary

2013-01-09T17:07:56+00:00

Apparently some users of managed input devices are confused whether
input_unregister_device() is needed when working with them. Clarify
this in the kernel doc for devm_input_allocate_device(): in most cases
there is no need to call neither input_unregister_device() nor
input_free_device() when working with managed devices.

Input: introduce managed input devices (add devres support)

2012-11-08T17:10:05+00:00

There is a demand from driver's writers to use managed devices framework
for their drivers. Unfortunately up to this moment input devices did not
provide support for managed devices and that lead to mixing two styles
of resource management which usually introduced more bugs, such as
manually unregistering input device but relying in devres to free
interrupt handler which (unless device is properly shut off) can cause
ISR to reference already freed memory.

This change introduces devm_input_allocate_device() that will allocate
managed instance of input device so that driver writers who prefer
using devm_* framework do not have to mix 2 styles.

Input: fix sparse warning in __input_release_device()

2012-10-25T07:12:01+00:00

This fixes the following warning:

Input: extend the number of event (and other) devices

2012-10-08T16:37:55+00:00

Extend the amount of character devices, such as eventX, mouseX and jsX,
from a hard limit of 32 per input handler to about 1024 shared across
all handlers.

To be compatible with legacy installations input handlers will start
creating char devices with minors in their legacy range, however once
legacy range is exhausted they will start allocating minors from the
dynamic range 256-1024.
