Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
"Items of note:
- evdev users can now limit or mask the kind of events they will
receive. This will allow applications such as power manager or
network manager to only be woken when user presses special keys
such as KEY_POWER or KEY_WIFI and not be bothered with ordinary
key presses coming from keyboard
- support for FocalTech FT6236 touchscreen controller
- support for ROHM BU21023/24 touchscreen controller
- edt-ft5x06 touchscreen driver got a face lift and can now be used
with FT5506
- support for Google Fiber TV Box remote controls
- improvements in xpad driver (with more to come)
- several parport-based drivers have been switched to the new device
model
- other miscellaneous driver improvements"

Introduction +~~~~~~~~~~~~~~~ + This module is intended to try to make the lives of input driver developers +easier by allowing them to test various serio devices (mainly the various +touchpads found on laptops) without having to have the physical device in front +of them. userio accomplishes this by allowing any privileged userspace program +to directly interact with the kernel's serio driver and control a virtual serio +port from there. + +2. Usage overview +~~~~~~~~~~~~~~~~~ + In order to interact with the userio kernel module, one simply opens the +/dev/userio character device in their applications. Commands are sent to the +kernel module by writing to the device, and any data received from the serio +driver is read as-is from the /dev/userio device. All of the structures and +macros you need to interact with the device are defined in <linux/userio.h> and +<linux/serio.h>. + +3. Command Structure +~~~~~~~~~~~~~~~~~~~~ + The struct used for sending commands to /dev/userio is as follows: + + struct userio_cmd { + __u8 type; + __u8 data; + }; + + "type" describes the type of command that is being sent. This can be any one +of the USERIO_CMD macros defined in <linux/userio.h>. "data" is the argument +that goes along with the command. In the event that the command doesn't have an +argument, this field can be left untouched and will be ignored by the kernel. +Each command should be sent by writing the struct directly to the character +device. In the event that the command you send is invalid, an error will be +returned by the character device and a more descriptive error will be printed +to the kernel log. Only one command can be sent at a time, any additional data +written to the character device after the initial command will be ignored. + To close the virtual serio port, just close /dev/userio. + +4. Commands +~~~~~~~~~~~ + +4.1 USERIO_CMD_REGISTER +~~~~~~~~~~~~~~~~~~~~~~~ + Registers the port with the serio driver and begins transmitting data back and +forth. Registration can only be performed once a port type is set with +USERIO_CMD_SET_PORT_TYPE. Has no argument. + +4.2 USERIO_CMD_SET_PORT_TYPE +~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + Sets the type of port we're emulating, where "data" is the port type being +set. Can be any of the macros from <linux/serio.h>. For example: SERIO_8042 +would set the port type to be a normal PS/2 port. + +4.3 USERIO_CMD_SEND_INTERRUPT +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + Sends an interrupt through the virtual serio port to the serio driver, where +"data" is the interrupt data being sent. + +5. Userspace tools +~~~~~~~~~~~~~~~~~~ + The userio userspace tools are able to record PS/2 devices using some of the +debugging information from i8042, and play back the devices on /dev/userio. The +latest version of these tools can be found at: + + https://github.com/Lyude/ps2emu diff --git a/MAINTAINERS b/MAINTAINERS index 0f327cce301e..e2b8cbbfcd8d 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -11306,6 +11306,12 @@ S: Maintained F: drivers/media/v4l2-core/videobuf2-* F: include/media/videobuf2-* +VIRTUAL SERIO DEVICE DRIVER +M: Stephen Chandler Paul <thatslyude@gmail.com> +S: Maintained +F: drivers/input/serio/userio.c +F: include/uapi/linux/userio.h + VIRTIO CONSOLE DRIVER M: Amit Shah <amit.shah@redhat.com> L: virtualization@lists.linux-foundation.org diff --git a/arch/arm/boot/dts/am437x-sk-evm.dts b/arch/arm/boot/dts/am437x-sk-evm.dts index 7da7c2da4af1..0bb36e9af936 100644 --- a/arch/arm/boot/dts/am437x-sk-evm.dts +++ b/arch/arm/boot/dts/am437x-sk-evm.dts @@ -502,7 +502,7 @@ reg = <0x38>;
