2015-08-07Input: elants_i2c - wire up regulator supportDmitry Torokhov1-22/+162
Elan touchscreen controllers use two power supplies, vcc33 and vccio, and we need to enable them before trying to access the device. On X86 firmware usually does this, but on ARM it is usually left to the kernel.

2015-08-04Input: atmel_mxt_ts - use deep sleep mode when stoppedNick Dyer1-11/+108
The hardcoded 0x83 CTRL setting overrides other settings in that byte, enabling extra reporting that may not be useful on a particular platform. Implement improved suspend mechanism via deep sleep. By writing zero to both the active and idle cycle times the maXTouch device can be put into a deep sleep mode, using minimal power. It is necessary to issue a calibrate command after the chip has spent any time in deep sleep, however a soft reset is unnecessary. Use the old method on Chromebook Pixel via platform data option. This patch also deals with the situation where the power configuration is zero on probe, which would mean that the device never wakes up to execute commands. After a config download, the T7 power configuration may have changed so it is necessary to re-read it.

2015-08-03Input: zforce - make the interrupt GPIO optionalDirk Behme1-14/+49
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.

2015-08-03thermal: consistently use int for temperaturesSascha Hauer1-4/+4
The thermal code uses int, long and unsigned long for temperatures in different places. Using an unsigned type limits the thermal framework to positive temperatures without need. Also several drivers currently will report temperatures near UINT_MAX for temperatures below 0°C. This will probably immediately shut the machine down due to overtemperature if started below 0°C. 'long' is 64bit on several architectures. This is not needed since INT_MAX °mC is above the melting point of all known materials. Consistently use a plain 'int' for temperatures throughout the thermal code and the drivers. This only changes the places in the drivers where the temperature is passed around as pointer, when drivers internally use another type this is not changed.

2015-07-30Input: touchscreen - export OF module alias informationJavier Martinez Canillas2-0/+2
The I2C core always reports the MODALIAS uevent as "i2c:<client name" regardless if the driver was matched using the I2C id_table or the of_match_table. So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

2015-07-23Input: tc3589x-keypad - change name of wakeup propertyDmitry Torokhov1-1/+4
Wakeup property of device is not Linux-specific, it describes intended system behavior regardless of the OS being used. Therefore let's drop "linux," prefix, and, while at it, use the same name as I2C bus does: "wakeup-source". We keep parsing old name to keep compatibility with old DTSes.
