2016-06-28input: touchscreen: fusion: implement multitouch with slot handlingStefan Agner
According to multi-touch-protocol.txt the kernel knows two type of devices: - Type A: devices which provide anonymous contacts - Type B: devices which are capable of tracking individual contacts The Fusion touch screen is a Type B device: The Touch ID field allows to differentiate between 2 different fingers. This updates the driver to properly allocate a slot for each identified contact and use the helper functions available from the input core system.
2016-06-28input: touchscreen: fusion: use level triggered interruptStefan Agner
Use level triggered interrupt which makes sure that even we miss a rising edge (due to latencies in the kernel), the interrupt still will be handled later, and doesn't freeze the input device.
2016-06-28input: touchscreen: fusion: add device tree integrationMax Krummenacher
Add device tree integration and add the device to the dtb. i2c device, interrupt and reset GPIO can be specified in the dts as follows: Note that additionally you may have to set the pinmuxing for the pins to be GPIO. &i2c1 { status = "okay"; pcap@10 { /* TouchRevolution Fusion 7 and 10 multi-touch controller */ compatible = "touchrevolution,fusion-f0710a"; reg = <0x10>; gpios = <&gpio6 10 0 /* MXM-11, Pen down interrupt */ &gpio6 9 0 /* MXM-13, Reset interrupt */ >; };
2016-06-28input: touchscreen: fusion: platform independent GPIO descriptionStefan Agner
Use platform independent description for requested GPIOs. (cherry picked from commit c300f3a605f8984449c1a5324fd3edda6f2fd8ff)
2016-06-28input: touchscreen: fusion: fix error handlingStefan Agner
Fix chip reset by sleeping long enought after reset. Do proper error handling (free GPIO on failure). Use dev_* for message logging to get similar messages for all fusion driver related errors and warnings. (cherry picked from commit 63b293000723e61a880470f093fbe82e86ebd81b)
2016-06-28input: touchscreen: fusion: use new I2C PM functionsStefan Agner
To avoid warnings use the new I2C power management function for suspend and resume. (cherry picked from commit 9d996316a470d37fb71c521f27106b014f3f0b23)
2016-06-28input: touchscreen: added platform data for Fusion touchscreenStefan Agner
Added platform data struct to define interrupt and reset GPIO. This allows to initialize the touchscreen controller inside the driver rather then in each platform and use the driver as a module. (cherry picked from commit cb82730b70f31af3b43041ac4e47de69c18016c9)
2016-06-28input: touchscreen: fix race condition in Fusion driverStefan Agner
When the next interrupt request apeares between the confirmation of the previous (a write via I2C, fusion_F0710A_write_complete) and the reenable of the GPIO interrupt, the driver hangs and no more touch inputs are reported. This patch moves the confirmation after the reenabling of the GPIO interrupt. (cherry picked from commit e95019a4f20b8cdfbe03658e4f73b69cdcf97540)
2016-06-28input: touchscreen: add ABS_X/ABS_Y axis for Fusion touchscreenStefan Agner
Recent evdev X-Server input driver implementation complain when only multitouch axes have been reported ("found only multitouch-axes. That shouldn't happen."). Therefor also report the primary touch detection with default axis. (cherry picked from commit dda7a631ac901e4d140e8a6612c5c6b5506b6a91)

On i.MX6UL EVK board, we use a external GPIO DC regulator to control the VDD_ARM_SOC_IN voltage, if default voltage is 1.4V when the system is bootup. Per design team, when the highest setpoint freq is not bigger than 528MHz, we can decrease this regulator voltage to 1.3V. On i.MX6UL TO1.1, we add a 700MHz setpoint. When the highest setpoint freq is 700MHz, the DC regulator should be at 1.4V to to cover the IR drop.

2016-06-24ARM: imx: fix clock for i.MX 7 when Cortex-M4 is runningStefan Agner
Commit b0149f1c7c ("MLK-11620 ARM: imx: single SOC config/compile support") ifdef'd clock functionality for SoloX only if Cortex-M4 is running. However, i.MX 7 also provides a Cortex-M4, hence the true branch in those if statements have been taken. Since the whole block was ifdef'd, the functions were rendered useless for i.MX 7.

2016-06-24ARM: dts: imx7d-colibri: Work around poweroff issueStefan Agner
The AD7879 interrupt GPIO is a wakeup pin. On poweroff, the external pull-up is not holding the GPIO high, hence causing a falling edge on the pad. Since the GPIO is a wakeup pin, this causes the SNVS Dumb PMIC to switch to on again (hence causing a reboot instead of a power- off). Make sure the interrupt line stays high during poweroff by configuring a pull-up on the IOMUXC LPSR GPR.
