Input: move USB touchscreens under drivers/input/touchscreen

2007-05-08T05:41:29Z

This will allow concentrating all input devices in one place in {menu|x|q}config. Signed-off-by: Dmitry Torokhov Acked-by: Greg Kroah-Hartman

Input: drivers/usb/input - usb_buffer_free() cleanup

2007-05-03T04:57:29Z

usb_buffer_free() now handles NULLs so remove unneeded checks form callers. Signed-off-by: Dmitry Torokhov

Input: USB devices - switch to using input_dev->dev.parent

2007-04-12T05:35:03Z

In preparation for struct class_device -> struct device input core conversion, switch to using input_dev->dev.parent when specifying device position in sysfs tree. Signed-off-by: Dmitry Torokhov

Input: drivers/usb/input - don't access dev->private directly

2007-04-12T05:34:39Z

Use input_get_drvdata() and input_set_drvdata() instead. Signed-off-by: Dmitry Torokhov

usbtouchscreen: make ITM screens report BTN_TOUCH as zero when not touched

2007-01-22T19:46:55Z

ITM screens send invalid x/y data when not touched. this was fixes a while ago but the problem is if the screen is not touched anymore the driver never does not report BTN_TOUCH as zero. fix it by sending the report with the last valid coordinates when pressure is released.

usbtouchscreen: add support for DMC TSC-10/25 devices

2006-12-01T22:23:37Z

Adds support for the DMC TSC-10 and TSC-25 usb touchscreen controllers. Signed-off-by: Holger Schurig Signed-off-by: Daniel Ritz Signed-off-by: Greg Kroah-Hartman

usbtouchscreen: use endpoint address from endpoint descriptor

2006-11-03T19:57:18Z

use the endpoint address from the endpoint descriptor instead of the hardcoding it to 0x81. at least some ITM based screen use a different address and don't work without this. Signed-off-by: Daniel Ritz Cc: Ralf Lehmann Cc: J.P. Delport Signed-off-by: Greg Kroah-Hartman

usbtouchscreen: fix data reading for ITM touchscreens

2006-10-17T21:46:34Z

ITM devices seem to report only garbage when not touched. update usbtouchscreen to do data reading like itmtouch. also fix wrong mask on pressure bits. Signed-off-by: Daniel Ritz Signed-off-by: Greg Kroah-Hartman

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers

2006-10-05T14:10:12Z

Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t. Signed-Off-By: David Howells (cherry picked from 1b16e7ac850969f38b375e511e3fa2f474a33867 commit)
