      Input: elan_i2c - set input device's vendor and product IDs · 3eab4588
      Charlie Mooney authored
      Previously the "vendor" and "product" IDs for the elan_i2c driver simply
      reported 0000.  This patch modifies the elan_i2c driver to include the
      Elan vendor ID and the touchpad's product id under
      input/input*/{vendor,product}.
      
      Specifically, this is to allow us to apply a generic Elan gestures config
      that will apply to all Elan touchpads on ChromeOS.  These configs  match to
      input devices in various ways, but one major way is by matching on vendor
      ID.  Adding this patch allows the default Elan touchpad config to be
      applied to Elan touchpads in this kernel by matching on devices that have
      vendor ID 04f3.
      
      Note that product ID is also available via custom sysfs entry "product_id"
      as well.

      Input: atmel_mxt_ts - add maxtouch to I2C table for module autoload · b7d21058
      Javier Martinez Canillas authored
      The Atmel maxtouch DT binding documents that the compatible string for
      the device is "atmel,maxtouch" and the I2C core always reports a module
      alias of the form i2c:alias where alias is the compatible string model:
      
      $ grep MODALIAS /sys/devices/platform/12e00000.i2c/i2c-8/8-004b/uevent
      MODALIAS=i2c:maxtouch
      
      But there isn't maxtouch entry in the I2C device ID table so when the
      i2c:maxtouch MODALIAS uevent is reported, kmod is not able to match the
      alias with a module to load:
      
      $ modinfo atmel_mxt_ts | grep alias
      alias:          of:N*T*Catmel,maxtouch
      alias:          i2c:mXT224
      alias:          i2c:atmel_mxt_tp
      alias:          i2c:atmel_mxt_ts
      alias:          i2c:qt602240_ts
      
      So add the maxtouch entry to the I2C device ID table to allow the module
      to be autoloaded when the device is registered via OF.

      Input: add userio module · 5523662e
      Stephen Chandler Paul authored
      Debugging input devices, specifically laptop touchpads, can be tricky
      without having the physical device handy. Here we try to remedy that
      with userio. This module allows an application to connect to a character
      device provided by the kernel, and emulate any serio device. In
      combination with userspace programs that can record PS/2 devices and
      replay them through the /dev/userio device, this allows developers to
      debug driver issues on the PS/2 level with devices simply by requesting
      a recording from the user experiencing the issue without having to have
      the physical hardware in front of them.

      Input: evdev - add event-mask API · 06a16293
      David Herrmann authored
      Hardware manufacturers group keys in the weirdest way possible. This may
      cause a power-key to be grouped together with normal keyboard keys and
      thus be reported on the same kernel interface.
      
      However, user-space is often only interested in specific sets of events.
      For instance, daemons dealing with system-reboot (like systemd-logind)
      listen for KEY_POWER, but are not interested in any main keyboard keys.
      Usually, power keys are reported via separate interfaces, however,
      some i8042 boards report it in the AT matrix. To avoid waking up those
      system daemons on each key-press, we had two ideas:
       - split off KEY_POWER into a separate interface unconditionally
       - allow filtering a specific set of events on evdev FDs
      
      Splitting of KEY_POWER is a rather weird way to deal with this and may
      break backwards-compatibility. It is also specific to KEY_POWER and might
      be required for other stuff, too. Moreover, we might end up with a huge
      set of input-devices just to have them properly split.
      
      Hence, this patchset implements the second idea: An event-mask to specify
      which events you're interested in. Two ioctls allow setting this mask for
      each event-type. If not set, all events are reported. The type==0 entry is
      used same as in EVIOCGBIT to set the actual EV_* mask of filtered events.
      This way, you have a two-level filter.
      
      We are heavily forward-compatible to new event-types and event-codes. So
      new user-space will be able to run on an old kernel which doesn't know the
      given event-codes or event-types.

      Input: alps - only the Dell Latitude D420/430/620/630 have separate stick button bits · 19556219
      Hans de Goede authored
      commit 92bac83d ("Input: alps - non interleaved V2 dualpoint has
      separate stick button bits") assumes that all alps v2 non-interleaved
      dual point setups have the separate stick button bits.
      
      Later we limited this to Dell laptops only because of reports that this
      broke things on non Dell laptops. Now it turns out that this breaks things
      on the Dell Latitude D600 too. So it seems that only the Dell Latitude
      D420/430/620/630, which all share the same touchpad / stick combo,
      have these separate bits.
      
      This patch limits the checking of the separate bits to only these models
      fixing regressions with other models.
