Revert "Input: i8042 - disable active multiplexing by default"

2014-10-31T16:35:53Z

This reverts commit 68da166491655bc54051bf04c78ce648e2e33508. It turns out that the assertion about scope of regressions due to always keeping keyboard controller in legacy mode was proven wrong. There are laptops, such as Clevo W650SH, that only have internal touchpad (no external PS/2 ports), that require active multiplexing mode to switch the touchpad (Elantech) into native mode instead of basic PS/2 emulation.

Input: altera_ps2 - use correct type for irq return value

2014-10-31T16:32:02Z

The irq function altera_ps2_rxint returns an irqreturn_t, so use the same type for variable storing the return value. Signed-off-by: Tobias Klauser Signed-off-by: Dmitry Torokhov

Input: altera_ps2 - write to correct register when disabling interrupts

2014-10-31T16:31:57Z

In altera_ps2_close, the data register (offset 0) is written instead of the control register (offset 4), leading to the RX interrupt not being disabled. Fix this by calling writel() with the offset for the proper register. Signed-off-by: Tobias Klauser Signed-off-by: Dmitry Torokhov

Input: i8042 - quirks for Fujitsu Lifebook A544 and Lifebook AH544

2014-10-24T21:56:55Z

These models need i8042.notimeout, otherwise the touchpad will not work. BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=69731 BugLink: https://bugzilla.redhat.com/show_bug.cgi?id=1111138 Cc: stable@vger.kernel.org Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Input: i8042 - disable active multiplexing by default

2014-10-11T18:34:43Z

Active multiplexing is a nice feature as it allows several pointing devices (such as touchpad and external mouse) use their native protocols at the same time. Unfortunately many manufacturers do not implement the feature properly even though they advertise it. The problematic implementations are never fixed, since Windows by default does not use this mode, and move from one BIOS/model of laptop to another. When active multiplexing is broken turning it on usually results in touchpad, keyboard, or both unresponsive. With PS/2 usage on decline (most of PS/2 devices in use nowadays are internal laptop touchpads), I expect number of users who have laptops with working MUX implementation, docking stations with external PS/2 ports, and who are still using external PS/2 mice, to be rather small. Let's flip the default to be OFF and allow activating it through i8042.nomux=0 kernel option. We'll also keep DMI table where we can record known good models.

Input: i8042 - add noloop quirk for Asus X750LN

2014-10-11T18:34:42Z

Without this the aux port does not get detected, and consequently the touchpad will not work. https://bugzilla.redhat.com/show_bug.cgi?id=1110011 Cc: stable@vger.kernel.org Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov

Merge tag 'v3.17' into next

Fix the format string for serio device name generation to avoid negative device numbers when the id exceeds the maximum signed integer value. Signed-off-by: Richard Leitner Signed-off-by: Dmitry Torokhov

Input: i8042 - fix Asus X450LCP touchpad detection

2014-09-24T23:26:56Z

We need to add this module to the nomux table to be able to detect the touchpad. Cc: stablevger.kernel.org Signed-off-by: Marcos Paulo de Souza Signed-off-by: Dmitry Torokhov

Input: i8042 - also set the firmware id for MUXed ports

So that firmware-id matching can be used with multiplexed aux ports too. Signed-off-by: Hans de Goede Signed-off-by: Dmitry Torokhov
