2015-08-04Input: zforce - make the interrupt GPIO optionalDirk Behme1-4/+4
Add support for hardware which uses an I2C Serializer / Deserializer (SerDes) to communicate with the zFroce touch driver. In this case the SerDes will be configured as an interrupt controller and the zForce driver will have no access to poll the GPIO line. To support this, we add two dedicated new GPIOs in the device tree: reset-gpios and irq-gpios, with the irq-gpios being optional. To not break the existing device trees, the index based 'gpios' entries are still supported, but marked as deprecated. With this, if the interrupt GPIO is available, either via the old or new device tree style, the while loop will read and handle the packets as long as the GPIO indicates that the interrupt is asserted (existing, unchanged driver behavior). If the interrupt GPIO isn't available, i.e. not configured via the new device tree style, we are falling back to one read per ISR invocation (new behavior to support the SerDes). Note that the gpiod functions help to handle the optional GPIO: devm_gpiod_get_index_optional() will return NULL in case the interrupt GPIO isn't available. And gpiod_get_value_cansleep() does cover this, too, by returning 0 in this case.

Add a new sun5i-a13-ts compatible to differentiate the newer models and set the curve based on the compatible string. The new curve is still not ideal on all A10-s, that seems to have to do with there being a large spread between different A10-s out there, the new curve us based on callibration results on 4 completely different models: raw min raw max temp min temp max stepsize offset Tong Zhang's hackberry 2402 2680 45.0 80.0 0.125 -255.3 Hansg's Cubieboard 2207 2300 36.0 45.0 0.096 -175.8 Olliver's lime 1 (*): 2258 2537 48.3 87.1 0.139 -265.7 Olliver's lime 2 (*): 2222 2486 46.7 91.7 0.170 -331.0 *) from: http://linux-sunxi.org/Temperature_Calibration Average all 4: 0.133 -257.0 Average without outliers (middle 2): 0.132 -261.0 Since it is better to slightly overreport the temperature this patch uses the average of all 4 as curve.

Many palmas family of PMICs have support for interrupt based power button. This allows the device to notify the processor of external push button events over the shared palmas interrupt. However, this event is generated only during a "press" operation. Software is supposed to poll(sigh!) for detecting a release event. The PMIC also supports ability to power off independent of the software decisions when the button is pressed for a long duration if the PMIC is appropriately configured on the platform. Even though the function is similar to twl4030_pwrbutton, it is substantially different in operation to belong to a new driver of it's own.

2014-09-09Input: add support for the DRV2667 haptic driverDan Murphy1-0/+17
Adding support for the DRV2667 haptic driver. This device has the ability to store vibration patterns in RAM and execute them once the GO bit is set. The initial driver sets a basic waveform in the first waveform sequence and will play the waveform when the GO bit is set and will continously play the waveform until the GO bit is unset.
