| | * | | Input: stmpe-ts - add DT support for stmpe touchscreenVipul Kumar Samar2012-11-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows the STMPE Touchscreen driver to be successfully probed and initialised when Device Tree support is enabled. Bindings are mentioned in Documentation too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In device tree enabled setups requiring preallocated memory for storing keymap is quite often awkward, so let's provide an option of allocating it directly in matrix_keypad_build_keymap().

| | * | | Input: introduce managed input devices (add devres support)Dmitry Torokhov2012-11-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

We have several new drivers, most of the time coming with their sub devices drivers: - Austria Microsystem's AS3711 - Nano River's viperboard - TI's TPS80031, AM335x TS/ADC, - Realtek's MMC/memstick card reader - Nokia's retu We also got some notable cleanups and improvements: - tps6586x got converted to IRQ domains. - tps65910 and tps65090 moved to the regmap IRQ API. - STMPE is now Device Tree aware. - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ APIs and a conversion to the recently added PWM framework. - sta2x11 gained regmap support. Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts. Many due to __devinit/exit removal, others due to one or two of the new drivers also having come in through another tree. * tag 'mfd-3.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6: (119 commits) mfd: tps6507x: Convert to devm_kzalloc mfd: stmpe: Update DT support for stmpe driver mfd: wm5102: Add readback of DSP status 3 register mfd: arizona: Log if we fail to create the primary IRQ domain mfd: tps80031: MFD_TPS80031 needs to select REGMAP_IRQ mfd: tps80031: Add terminating entry for tps80031_id_table mfd: sta2x11: Fix potential NULL pointer dereference in __sta2x11_mfd_mask() mfd: wm5102: Add tuning for revision B mfd: arizona: Defer patch initialistation until after first device boot mfd: tps65910: Fix wrong ack_base register mfd: tps65910: Remove unused data mfd: stmpe: Get rid of irq_invert_polarity mfd: ab8500-core: Fix invalid free of devm_ allocated data mfd: wm5102: Mark DSP memory regions as volatile mfd: wm5102: Correct default for LDO1_CONTROL_2 mfd: arizona: Register haptics devices mfd: wm8994: Make current device behaviour the default mfd: tps65090: MFD_TPS65090 needs to select REGMAP_IRQ mfd: Fix stmpe.c build when OF is not enabled mfd: jz4740-adc: Use devm_kzalloc ...

The FIFO can be shared between 2 devices but since the interrupt used is threshold interrupt on FIFO1, we would end up having wrong interrupts. Hence changing the same.

Program the Steps in order to configure a channel input to be sampled. If the same step is applied several times, the coordinate values read are more accurate. Hence we provide the user an option of how many steps should be configured. For ex: If this value is assigned as 4, This means that 4 steps are applied to read x co-ordinate and 4 steps to read y co-ordinate. Furtheron the interrupt handler already holds code to use delta filter and report the best value out of these values to the input sub-system.

Bit masks were not defined earlier. For ex: consider a register define as: write(xyz, ABC) ABC is expected to be written to register bits 0-11. Here we see that value written is as expected, but this write is also affecting all the remaining bits of xyz. The remaining bits hold the default value as 0 and the write also sets it to zero. Hence wrong usage were not causing user visible bugs. Due to these reasons it was difficult to follow when compared with TRM. Unused definitions are also removed. Since there is change in some naming convention because of all the above mentioned reasons, the same has been updated throughout the code. Bit declarations are grouped to increase readability.
