2010-12-20ARM: pxa: Push Colibri evalboard MFP into module filesMarek Vasut
This change -- pushing the MFP configuration back into Module files -- is necessary because some evalboards can be used with multiple modules, where MFP differs from module to module. Therefore MFP isn't board-specific, but module-specific and the module should preconfigure itself for the board. (And there is also the C preprocesor limitation and conflicting #define-s) Signed-off-by: Marek Vasut <marek.vasut@gmail.com> Acked-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>

2010-12-20Input: fix double equality sign in ueventHenrik Rydberg
Looking at the uevent stream for input devices, all properties are on the form "A=B" except the bitmap values, which are on the form "A==B". This bug has been around at least since 2007, and the input uevent code has been untouched since. The recent addition of device properties suggests this is a good time for a remedy.

2010-12-20Input: introduce device propertiesHenrik Rydberg
Today, userspace sets up an input device based on the data it emits. This is not always enough; a tablet and a touchscreen may emit exactly the same data, for instance, but the former should be set up with a pointer whereas the latter does not need to. Recently, a new type of touchpad has emerged where the buttons are under the pad, which changes logic without changing the emitted data. This patch introduces a new ioctl, EVIOCGPROP, which enables user access to a set of device properties useful during setup. The properties are given as a bitmap in the same fashion as the event types, and are also made available via sysfs, uevent and /proc/bus/input/devices.

2010-12-19ARM: fix cache-feroceon-l2 after stack based kmap_atomic()Nicolas Pitre
Since commit 3e4d3af501 "mm: stack based kmap_atomic()", it is actively wrong to rely on fixed kmap type indices (namely KM_L2_CACHE) as kmap_atomic() totally ignores them and a concurrent instance of it may happily reuse any slot for any purpose. Because kmap_atomic() is now able to deal with reentrancy, we can get rid of the ad hoc mapping here. While the code is made much simpler, there is a needless cache flush introduced by the usage of __kunmap_atomic(). It is not clear if the performance difference to remove that is worth the cost in code maintenance (I don't think there are that many highmem users on that platform anyway) but that should be reconsidered when/if someone cares enough to do some measurements.

Because kmap_atomic() is now able to deal with reentrancy, we can get rid of the ad hoc mapping here, and we even don't have to disable IRQs anymore (highmem case). While the code is made much simpler, there is a needless cache flush introduced by the usage of __kunmap_atomic().
