From dd5d2d7643d4dab3b88d2fdf85df726c37af0982 Mon Sep 17 00:00:00 2001 From: Leon Woestenberg Date: Thu, 21 Aug 2008 15:30:27 +0000 Subject: linux-2.6.25: Add virtual mouse driver, but for AVR32 only. The AT32STK1002 board comes with a non-touchscreen LCD; this driver helps to mimick touches on the screen. Currently, it sends the coordinates and a left mouse button click and release when performing echo "100 100 0" >/sys/devices/platform/vms/coordinates --- .../linux-2.6.25/at32stk1000/virtualmouse.patch | 125 +++++++++++++++++++++ packages/linux/linux_2.6.25.bb | 3 +- 2 files changed, 127 insertions(+), 1 deletion(-) create mode 100644 packages/linux/linux-2.6.25/at32stk1000/virtualmouse.patch (limited to 'packages') diff --git a/packages/linux/linux-2.6.25/at32stk1000/virtualmouse.patch b/packages/linux/linux-2.6.25/at32stk1000/virtualmouse.patch new file mode 100644 index 0000000000..b828327a00 --- /dev/null +++ b/packages/linux/linux-2.6.25/at32stk1000/virtualmouse.patch @@ -0,0 +1,125 @@ +Index: linux-2.6.25/drivers/input/Kconfig +=================================================================== +--- linux-2.6.25.orig/drivers/input/Kconfig 2008-04-17 04:49:44.000000000 +0200 ++++ linux-2.6.25/drivers/input/Kconfig 2008-08-21 16:37:40.000000000 +0200 +@@ -69,6 +69,13 @@ + To compile this driver as a module, choose M here: the + module will be called mousedev. + ++config INPUT_VMS ++ tristate "Virtual Mouse Driver" if EMBEDDED ++ default y ++ ---help--- ++ vms.c from the book Essential Linux Device Drivers ++ ++ + config INPUT_MOUSEDEV_PSAUX + bool "Provide legacy /dev/psaux device" + default y +Index: linux-2.6.25/drivers/input/Makefile +=================================================================== +--- linux-2.6.25.orig/drivers/input/Makefile 2008-04-17 04:49:44.000000000 +0200 ++++ linux-2.6.25/drivers/input/Makefile 2008-08-21 16:37:40.000000000 +0200 +@@ -11,6 +11,8 @@ + obj-$(CONFIG_INPUT_POLLDEV) += input-polldev.o + + obj-$(CONFIG_INPUT_MOUSEDEV) += mousedev.o ++ ++obj-$(CONFIG_INPUT_VMS) += vms.o + obj-$(CONFIG_INPUT_JOYDEV) += joydev.o + obj-$(CONFIG_INPUT_EVDEV) += evdev.o + obj-$(CONFIG_INPUT_EVBUG) += evbug.o +Index: linux-2.6.25/drivers/input/vms.c +=================================================================== +--- /dev/null 1970-01-01 00:00:00.000000000 +0000 ++++ linux-2.6.25/drivers/input/vms.c 2008-08-21 17:24:05.000000000 +0200 +@@ -0,0 +1,89 @@ ++/** ++ * Copyright (c) 2008 by Pearson Education, Inc. ++ * ++ * This material may be distributed only subject to the terms and conditions ++ * set forth in the Open Publication License, v1.0 or later (the latest version ++ * is presently available at http://www.opencontent.org/openpub/). ++ * ++ * Copyright (c) 2008 Leon Woestenberg ++ * Copyright (c) 2008 Sreekrishnan Venkateswaran ++ * ++ * I copied this from Sreekrishnan's book (see http://elinuxdd.com) -- Leon. ++ * ++ */ ++ ++#include ++#include ++#include ++#include ++ ++struct input_dev *vms_input_dev;
