Subject: input: touchscreen: remove msg21xx mstar touch driver
Remove msg21xx mstar touch driver from the kernel code
as it has never been used in any of the recent platforms.

-Mstar touch controller
-
-The mstar controller is connected to host processor
-via i2c. The controller generates interrupts when the
-user touches the panel. The host controller is expected
-to read the touch coordinates over i2c and pass the coordinates
-to the rest of the system.
-
-Required properties:
-
- - compatible : should be "mstar,msg21xx".
- - reg : i2c slave address of the device.
- - interrupt-parent : parent of interrupt.
- - interrupts : touch sample interrupt to indicate presense or release
- of fingers on the panel.
- - vdd-supply : Power supply needed to power up the device.
- - vcc_i2c-supply : Power source required to power up i2c bus.
- - mstar,irq-gpio : irq gpio which is to provide interrupts to host,
- same as "interrupts" node. It will also
- contain active low or active high information.
- - mstar,reset-gpio : reset gpio to control the reset of chip.
- - mstar,display-coords : display coords in pixels. It is a four
- tuple consisting of min x, min y, max x and
- max y values.
- - pinctrl-names : This should be defined if a target uses pinctrl framework.
- See "pinctrl" in Documentation/devicetree/bindings/pinctrl/msm-pinctrl.txt.
- Specify the names of the configs that pinctrl can install in driver.
- Following are the pinctrl configs that can be installed:
- "pmx_ts_active" : Active configuration of pins, this should specify active
- config defined in pin groups of interrupt and reset gpio.
- "pmx_ts_suspend" : Disabled configuration of pins, this should specify sleep
- config defined in pin groups of interrupt and reset gpio.
- "pmx_ts_release" : Release configuration of pins, this should specify
- release config defined in pin groups of interrupt and reset gpio.
- - mstar,num-max-touches: It defines the maximum number of touch supported by the controller.
- - mstar,hard-reset-delay-ms : hard reset delay in ms
- - mstar,post-hard-reset-delay-ms : post hard reset delay in ms
-
-Optional properties:
-
- - mstar,button-map : button map of key codes. It is a three tuple consisting of key codes.
- - mstar,panel-coords : panel coords for the chip in pixels.
- It is a four tuple consisting of min x,
- min y, max x and max y values.
- - mstar,ic-type : It defines the ic-type of the controller. Values are as folows:
- 1 -> msg2133.
- 2 -> msg21xxA.
- 3 -> msg26xxM.
-
-Example:
- i2c@78b9000 { /* BLSP1 QUP5 */
- mstar@26 {
- compatible = "mstar,msg21xx";
- reg = <0x26>;
- interrupt-parent = <&msm_gpio>;
- interrupts = <13 0x2008>;
- mstar,irq-gpio = <&msm_gpio 13 0x00000001>;
- mstar,reset-gpio = <&msm_gpio 12 0x0>;
- vdd-supply = <&pm8916_l17>;
- vcc_i2c-supply = <&pm8916_l6>;
- mstar,display-coords = <0 0 480 854>;
- pinctrl-names = "pmx_ts_active","pmx_ts_suspend";
- pinctrl-0 = <&ts_int_active &ts_reset_active>;
- pinctrl-1 = <&ts_int_suspend &ts_reset_suspend>;
- mstar,button-map = <172 139 158>;
- mstar,ic-type = <2>;
- mstar,num_max_touches = <2>;
- mstar,hard-reset-delay-ms = <100>;
- mstar,post-hard-reset-delay-ms = <100>;
