2013-10-31Input: i8042 - add PNP modaliasesTom Gundersen1-0/+2
This allows the module to be autoloaded in the common case. In order to work on non-PnP systems the module should be compiled in or loaded unconditionally at boot (c.f. modules-load.d(5)), as before.

2013-10-31Input: evdev - fall back to vmalloc for client event bufferDaniel Stone1-4/+12
evdev always tries to allocate the event buffer for clients using kzalloc rather than vmalloc, presumably to avoid mapping overhead where possible. However, drivers like bcm5974, which claims support for reporting 16 fingers simultaneously, can have an extraordinarily large buffer. The resultant contiguous order-4 allocation attempt fails due to fragmentation, and the device is thus unusable until reboot. Try kzalloc if we can to avoid the mapping overhead, but if that fails, fall back to vzalloc.

If hardware (or firmware) detects palm on the surface of the device it does not mean that the data packet is bad from the protocol standpoint.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: First round of new drivers, functionality and cleanups for IIO in the 3.13 cycle A number of new drivers and some new functionality + a lot of cleanups all over IIO. New Core Elements 1) New INT_TIME info_mask element for integration time, which may have different effects on measurement noise and similar, than an amplifier and hence is different from existing SCALE. Already existed in some drivers as a custom attribute. 2) Introduce a iio_push_buffers_with_timestamp helper to cover the common case of filling the last 64 bits of data to be passed to the buffer with a timestamp. Applied to lots of drivers. Cuts down on repeated code and moves a slightly fiddly bit of logic into a single location. 3) Introduce info_mask_[shared_by_dir/shared_by_all] elements to allow support of elements such as sampling_frequency which is typically shared by all input channels on a device. This reduces code and makes these controls available from in kernel consumers of IIO devices. New drivers 1) MCP3422/3/4 ADC 2) TSL4531 ambient light sensor 3) TCS3472/5 color light sensor 4) GP2AP020A00F ambient light / proximity sensor 5) LPS001WP support added to ST pressure sensor driver. New driver functionality 1) ti_am335x_adc Add buffered sampling support. This device has a hardware fifo that is fed directly into an IIO kfifo buffer based on a watershed interrupt. Note this will act as an example of how to handle this increasingly common type of device. The only previous example - sca3000 - take a less than optimal approach which is largely why it is still in staging. A couple of little cleanups for that new functionality followed later. Core cleanups: 1) MAINTAINERS - Sachin actually brought my email address up to date because I said I'd do it and never got around to it :) 2) Assign buffer list elements as single element lists to simplify the iio_buffer_is_active logic. 3) wake_up_interruptible_poll instead of wake_up_interruptible to only wake up threads waiting for poll notifications. 4) Add O_CLOEXEC flag to anon_inode_get_fd call for IIO event interface. 5) Change iio_push_to_buffers to take a void * pointer so as to avoid some annoying and unnecessary type casts. 6) iio_compute_scan_bytes incorrectly took a long rather than unsigned long. 7) Various minor tidy ups. Driver cleanups (in no particular order) 1) Another set of devm_ allocations patches from Sachin Kamat. 2) tsl2x7x - 0 to NULL cleanup. 3) hmc5843 - fix missing > in MODULE_AUTHOR 4) Set of strict_strto* to kstrto* conversions. 5) mxs-lradc - fix ordering of resource removal to match creation 6) mxs-lradc - add MODULE_ALIAS 7) adc7606 - drop a work pending test duplicated in core functions. 8) hmc5843 - devm_ allocation patch 9) Series of redundant breaks removed. 10) ad2s1200 - pr_err -> dev_err 11) adjd_s311 - use INT_TIME 12) ST sensors - large set of cleanups from Lee Jones and removed restriction to using only triggers provided by the st_sensors themselves from Dennis Ciocca. 13) dummy and tmp006 provide sampling_frequency via info_mask_shared_by_all. 14) tcs3472 - fix incorrect buffer size and wrong device pointer used in suspend / resume functions. 15) max1363 - use defaults for buffer setup ops as provided by the triggered buffer helpers as they are the same as were specified in max1363 driver. 16) Trivial tidy ups in a number of other drivers.

The EMR sensor of Intuos4 and newer devices can send a packet with 0x20 in its second byte which contains only location information. This packet is sent when the pen is too far away to reliably obtain other information. Because only the location is updated userspace will continue to see stale information for other values, most notably TOUCH, PRESSURE, and DISTANCE. This patch ensures userspace is not left with stale device state information when the pen re-enters proximity (possibly leading to the assumption the pen is still in contact even though it is actually hovering).

2013-09-18Input: i8042 - i8042_flush fix for a full 8042 bufferAndrey Moiseev1-9/+14
When 8042 internal data buffer is full, the driver erroneously decides that the controller is not present. i8042_flush returns the number of flushed bytes, which is in 0 - I8042_BUFFER_SIZE range inclusive. Therefore, i8042_flush has no way to indicate an error. Moreover i8042_controller_check takes initially full buffer (i8042_flush returned I8042_BUFFER_SIZE) as a sign of absence of the controller. Let's change i8042 to return success/error instead and make sure we do not return error prematurely.
