The S6SY761 touchscreen is a capicitive multi-touch controller
for mobile use. It's connected with i2c at the address 0x48.
This commit provides a basic version of the driver which can
handle only initialization, touch events and power states.
The controller is controlled by a firmware which, in the version
I currently have, doesn't provide all the possible
functionalities mentioned in the datasheet.

Hi,
sorry for the mix-up of the previous patch. This one should be
fine. Here's the changelog:
v3 - v4
- fixed a mismatch on the module name
v2 - v3
- added security check on an unsigned value which can (unlikely)
get a "negative" value
- in the probe function the interrupt is requested after the
input device registration in order to avoid checking in the
interrupt handler whether the input device has been registered
- removed the 'prev_pm_state' variable. Its original meaning
was to restore the state of the device when coming back from
sleep mode, but because I removed in patch v2 the low power
mode, now the device works only in two modes and therefore
'prev_pm_state' is not required any longer.
v1 - v2
- remove the low power functionality as it doesn't bring any
benefit
- use get_unaligned_be16 instead of the form 'a << 8 | b'
- use max_t instead of '? :'
- use managed 'devm_device_add_group()'
Thanks,
Andi

+* Samsung S6SY761 touchscreen controller
+
+Required properties:
+- compatible : must be "samsung,s6sy761"
+- reg : I2C slave address, (e.g. 0x48)
+- interrupt-parent : the phandle to the interrupt controller which provides
+ the interrupt
+- interrupts : interrupt specification
+- avdd-supply : analogic power supply
+- vdd-supply : power supply
+
+Optional properties:
+- touchscreen-size-x : see touchscreen.txt. This property is embedded in the
+ device. If defined it forces a different x resolution.
+- touchscreen-size-y : see touchscreen.txt. This property is embedded in the
+ device. If defined it forces a different y resolution.
+
+Example:
+
+i2c@00000000 {
+
+ /* ... */
+
+ touchscreen@48 {
+ compatible = "samsung,s6sy761";
+ reg = <0x48>;
+ interrupt-parent = <&gpa1>;
+ interrupts = <1 IRQ_TYPE_NONE>;
+ avdd-supply = <&ldo30_reg>;
+ vdd-supply = <&ldo31_reg>;
+ touchscreen-size-x = <4096>;
+ touchscreen-size-y = <4096>;
