| | * Input: trackpoint - Optimize trackpoint init to use power-on resetShawn Nematbakhsh2013-04-192-87/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The trackpoint driver sets various parameter default values, all of which happen to be power-on defaults (Source: IBM TrackPoint Engineering Specification, Version 4.0. Also confirmed by empirical data). By sending the power-on reset command to reset all parameters to power-on state, we can skip the lengthy process of programming all parameters. In testing, ~2.5 secs of time writing parameters was reduced to .35 seconds waiting for power-on reset to complete.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We no longer need to set up the reset pin for the st1232 in the board code, but can pass the GPIO number via the platform data to the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some devices have too few buttons, which it makes it hard to have a reset combo that won't trigger automatically. As such a timeout functionality that requires the combination to be held for a given amount of time before triggering is introduced. If a key combo is recognized and held for a 'timeout' amount of time, the system triggers a reset. If the timeout value is omitted the driver simply ignores the functionality.

It has a set of control buttons (Volume Up/Down, Attendant, Lights, etc) on one side and gamepad-like controls on the other side. Originally the device was handled from userspace and because of that it presents itself on USB bus as a CDC-ACM modem device that however can not make calls. However the custom handling is not as convenient as using standard input subsystem facilities. If it was pure input device it would be possible to continue using userspace solution (moving it over to uinput), but the device also has backlighted keys which can not be supported via uinput.

The abs_x and abs_y module parameters should fix this by default, but the driver doesn't actively checks the x/y coordinates. Instead it seems that the input layer was supposed to drop out of range inputs, as described in the comments: "These parameters are used to help the input layer discard out of range readings and reduce jitter etc" The input layer documentation describes that values that are not in the absolute range are also accepted. So this patch adds a check within the driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The arch_local_irq_save(), etc., routines are required to function as compiler barriers. They do, but it's subtle and requires knowing that the gcc builtin __insn_mtspr() is marked as a memory clobber. Provide a comment explaining the assumption.
