Some devices are not fast enough to differentiate between a fast-moving contact and a new contact. This problem cannot be fully resolved because information is truly missing, but it is possible to safe-guard against obvious mistakes by restricting movement with a maximum displacement. The new problem formulation for dmax > 0 cannot benefit from the speedup for positive definite matrices, but since the convergence is faster, the result is about the same. For a handful of contacts, the latency difference is truly negligible.

We now have a binding which adds two parameters to the matrix keypad DT node. This is separate from the GPIO-driven matrix keypad binding, and unfortunately incompatible, since that uses row-gpios/col-gpios for the row and column counts. So the easiest option here is to provide a function for non-GPIO drivers to use to decode the binding. Note: We could in fact create an entirely separate structure to hold these two fields, but it does not seem worth it, yet. If we have more parameters then we can add this, and then refactor each driver to hold such a structure.

There are 16 programmable Step Configuration registers which are used by the sequencer. 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.

Most MT drivers perform the same actions on frame synchronization. Some actions, like dropping unseen contacts, are also unnecessarily complex. Collect common frame synchronization tasks in a new function, input_mt_sync_frame(). Depending on the flags set, it drops unseen contacts and performs pointer emulation. With init flags and frame synchronization in place, most MT drivers can be simplified. First out are the bcm5974 and hid-multitouch drivers, following this patch.

由 Arnd Bergmann 提交于
The EETI touchscreen asserts its IRQ line as soon as it has data in its internal buffers. The line is automatically deasserted once all data has been read via I2C. Hence, the driver has to monitor the GPIO line and cannot simply rely on the interrupt handler reception. In the current implementation of the driver, irq_to_gpio() is used to determine the GPIO number from the i2c_client's IRQ value. As irq_to_gpio() is not available on all platforms, this patch changes this and makes the driver ignore the passed in IRQ. Instead, a GPIO is added to the platform_data struct and gpio_to_irq is used to derive the IRQ from that GPIO. If this fails, bail out. The driver is only able to work in environments where the touchscreen GPIO can be mapped to an IRQ. Without this patch, building raumfeld_defconfig results in: drivers/input/touchscreen/eeti_ts.c: In function 'eeti_ts_irq_active': drivers/input/touchscreen/eeti_ts.c:65:2: error: implicit declaration of function 'irq_to_gpio' [-Werror=implicit-function-declaration] Signed-off-by: NDaniel Mack <zonque@gmail.com> Signed-off-by: NArnd Bergmann <arnd@arndb.de> Cc: stable@vger.kernel.org (v3.2+) Cc: Dmitry Torokhov <dmitry.torokhov@gmail.com> Cc: Sven Neumann <s.neumann@raumfeld.com> Cc: linux-input@vger.kernel.org Cc: Haojian Zhuang <haojian.zhuang@gmail.com>
