2009-11-02Input: i8042 - try to get stable CTR value when initializingDmitry Torokhov
If user presses keys while i8042 is being initialized there is a chance that keyboard data will be mistaken for results of Read Control Register command causing futher troubles. Work around this issue by reading CTR several times and stop when we get matching results. Reported-and-tested-by: Dave Young <hidave.darkstar@gmail.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>

2009-10-18Input: i8042 - add Sony Vaio VGN-FZ240E to the nomux listDmitry Torokhov
On this model, when KBD is in active multiplexing mode, acknowledgements to reset and get ID commands issued on KBD port sometimes are delivered to AUX3 port (touchpad) which messes up device detection. Legacy KBC mode works fine and since there are no external PS/2 ports on this laptop and no support for docking station we can safely disable active MUX mode. Tested-by: Carlos R.

2009-09-17Input: libps2 - additional locking for i8042 portsDmitry Torokhov
The serio ports on i8042 are not completely isolated; while we provide enough locking to ensure proper serialization when accessing control and data registers AUX and KBD ports can still have an effect on each other on PS/2 protocol level. The most prominent effect is that issuing a command for the device connected to one port may cause abort of the command currently executing by the device connected to another port. Since i8042 nor serio subsystem are not aware of the details of the PS/2 protocol (length of the commands and their replies and so on) the locking should be done on libps2 level by adding special handling when we see that we are dealing with serio port on i8042.

2009-09-10Input: i8042 - try disabling and re-enabling AUX port at closeDmitry Torokhov
Ever since we switched from having a polling timer to registering IRQ handlers for both keyboard and AUX ports at the driver registration time, on certain boxes probing for a mouse results in keyboard stopping working. The only real difference between old and new way is that before we disabled ports after unsuccessful probe whereas now we leave them as is. Try to emulate the old behavior by disabling and immediately re-enabling AUX and KBD ports when corresponding serio port is being closed. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
2009-09-10Input: i8042 - bypass AUX IRQ delivery test on laptopsDmitry Torokhov
It seems that many laptops do not fully implement AUX LOOP command in their keyboard controllers, causing issues with touchpad detection. We know however that almost every laptop/portable uses a PS/2 pointing device and, even if user disables it in favor of an external mouse, the system will not use IRQ 12 for anything else. Therefore we may bypass AUX IRQ delivery test when running on a laptop and assume that it is routed properly. Just to be safe we require the box to have good PNP data in order to bypass the test.

2009-07-07Input: mark serio and i8042 as suspended when hibernating tooThadeu Lima de Souza Cascardo
Serio ports are not being restarted any longer because resume operations after hibernate do nothing, since the device has not been marked as suspended. This happens because suspend is only considering the SUSPEND event but not the FREEZE event. Note that this driver has still to migrate to dev_pm_ops, but this fixes this particular bug now.

2009-06-11[ARM] 5544/1: Trust PrimeCell resource sizesLinus Walleij
I found the PrimeCell/AMBA Bus drivers distrusting the resource passed in as part of the struct amba_device abstraction. This patch removes all hard coded resource sizes found in the PrimeCell drivers and move the responsibility of this definition back to the platform/board device definition, which already exist and appear to be correct for all in-tree users of these drivers. We do this using the resource_size() inline function which was also replicated in the only driver using the resource size, so that has been changed too. The KMI_SIZE was left in kmi.h in case someone likes it. Test-compiled against Versatile and Integrator defconfigs, seems to work but I don't posess these boards and cannot test them.

Sometimes devices send us their responses in time but due to unfortunate scheduling decisions the receiving thread does not get scheduled till much later and we erroneously decide that device timed out.

2009-04-21drivers/input/serio/hp_sdc.c: fix crash when removing hp_sdc moduleHelge Deller
On parisc machines, which don't have HIL, removing the hp_sdc module panics the kernel. Fix this by returning early in hp_sdc_exit() if no HP SDC controller was found. Add functionality to probe for the hp_sdc_mlc kernel module (which takes care of the upper layer HIL functionality on parisc) after two seconds. This is needed to get all the other HIL drivers (keyboard / mouse/ ..) drivers automatically loaded by udev later as well.

2009-03-16Rationalize fasync return valuesJonathan Corbet
Most fasync implementations do something like: return fasync_helper(...); But fasync_helper() will return a positive value at times - a feature used in at least one place. Thus, a number of other drivers do: err = fasync_helper(...); if (err < 0) return err; return 0; In the interests of consistency and more concise code, it makes sense to map positive return values onto zero where ->fasync() is called.
