2011-05-26mfd: Use mfd cell platform_data for twl4030 codec cells platform bitsSamuel Ortiz
With the addition of a platform device mfd_cell pointer, MFD drivers can go back to passing platform data back to their sub drivers. This allows for an mfd_cell->mfd_data removal and thus keep the sub drivers MFD agnostic. This is mostly needed for non MFD aware sub drivers.

2011-05-17Input: tsc2007 - add max_rt parameter to platform dataThierry Reding
Finger touch events or very quick stylus events on low-quality panels can cause the tsc2007 to read bogus values. Looking at oscilloscope snapshots, this seems to be caused by the touch event disappearing during the measurements. These bogus values result in misclicks, where the X and Y values deviate from the real position. Most of these misclicks can be filtered out by setting a low enough threshold for the maximum resistance (which is loosely the inverse of the pressure) allowed to consider a set of values valid. Since this behaviour is largely dependent on the type and quality of the panel, this commit introduces the max_rt parameter. The default value is kept at MAX_12BIT.

2011-05-17Input: elantech - remove support for proprietary X driverÉric Piel
Apparently somewhere someone had a proprietary X driver. To get the multitouch info, it uses some hack on the normal API instead of using the multitouch protocol. Now that the multitouch info is transmitted correctly it makes not much sense to keep it. Especially because it's impossible to find this proprietary X driver anywhere, so the number of users must be very low.

2011-05-17Input: elantech - report multitouch with proper ABS_MT messagesÉric Piel
Multitouch info was reported only via a old protocol used by the proprietary X driver from elantech. Let's report the multitouch info also following the official MT protocol. It's semi-mt because the device only reports the lowest/highest coordinates. This was done following the multi-touch-protocol.txt documentation, and inspired by the bcm5974 and elantech implementations. Testing was light as there is not many applications using this protocol yet, but the X synaptics driver didn't complain and the X multitouch driver behaved correctly.

2011-05-12arch/tile: finish enabling support for TILE-Gx 64-bit chipChris Metcalf
This support was partially present in the existing code (look for "__tilegx__" ifdefs) but with this change you can build a working kernel using the TILE-Gx toolchain and ARCH=tilegx. Most of these files are new, generally adding a foo_64.c file where previously there was just a foo_32.c file. The ARCH=tilegx directive redirects to arch/tile, not arch/tilegx, using the existing SRCARCH mechanism in the top-level Makefile. Changes to existing files: - <asm/bitops.h> and <asm/bitops_32.h> changed to factor the include of <asm-generic/bitops/non-atomic.h> in the common header. - <asm/compat.h> and arch/tile/kernel/compat.c changed to remove the "const" markers I had put on compat_sys_execve() when trying to match some recent similar changes to the non-compat execve. It turns out the compat version wasn't "upgraded" to use const. - <asm/opcode-tile_64.h> and <asm/opcode_constants_64.h> were previously included accidentally, with the 32-bit contents. Now they have the proper 64-bit contents. Finally, I had to hack the existing hacky drivers/input/input-compat.h to add yet another "#ifdef" for INPUT_COMPAT_TEST (same as x86_64).

2011-04-28Input: wm831x-ts - fix races with IRQ managementMark Brown
If the WM831x pen down and data IRQs run in parallel it is possible for the data and pen down IRQs to deadlock themselves as one is part way through disabling its operation while the other is part way through enabling. Fix this by always disabling the pen down interrupt while data is active and vice versa. When a changeover is required we disable the IRQ that is to be stopped then schedule work that will enable the new IRQ. We need to handle the data flow in the data IRQ as the readback from the device needs to be ordered correctly with the IRQ for robust operation. This also fixes an issue when using the built in IRQs due to enable_irq() not being valid from interrupt context on an interrupt controller with bus operations like the built in IRQ controller - this issue may also have affected other interrupt controllers. We can't rely on having the data and pen down IRQs available via GPIOs on the CPU on every system.
