Now that alps_identify() explicitly issues an EC report using alps_rpt_cmd(), we no longer need to look at the magic numbers returned by alps_enter_command_mode(). Signed-off-by:

Tegra only supports, and always enables, device tree. Remove all ifdefs and runtime checks for DT support from the driver. Platform data is therefore no longer required. Delete the header that defines it, and rework the driver to parse the device tree directly into struct tegra_kbc. Signed-off-by:

To properly setup event parameters for emulated events, pass the appropriate flag to the slot initialization function. Also, all MT-related events should be setup before initialization. Incidentally, this solves the issue of doubly filtered pointer events. Reported-by:

Make the constants referring to range and bandwidth public so they can be used when initializing the platform data fields in the platform code. Fix also some comments regarding the unit of measurement to use for the range and bandwidth fields, the values are not actually expected to be in G or HZ, the code in bma150.c just uses the BMA150_RANGE_xxx and BMA150_BW_xxx constants like they are with no translation from actual values in G or HZ.

When PM_RUNTIME is not defined, pm_runtime_get_sync() returns 1, see include/linux/pm_runtime.c::__pm_runtime_resume(), and the check of the return value was overlooking this, in this case bma150_open() would return 1 which is not expected by upper layers. Maybe the check for != -ENOSYS (Function not implemented) was meant to cover this, but pm_runtime_get_sync() does not return this value. For now fix the issue locally by checking explicitly for negative return values. Signed-off-by:

Rushmore touchpads are found on Dell E6230/E6430/E6530. They use the V3 protocol with slightly tweaked init sequences and report formats. The E7 report is 73 03 0a, and the EC report is 88 08 1d Credits: Emmanuel Thome reported the MT bitmap changes. Signed-off-by:

If the E6 report test passes, get the E7 and EC reports right away and then try to match an entry in the table. Pass in the alps_data struct, so that the detection code will be able to set operating parameters based on information found during detection. Change the version (psmouse->model) to report the protocol version only, in preparation for supporting models that do not show up in the ID table. Signed-off-by:

Not every type of ALPS touchpad is well-suited to table-based detection. Start moving the various alps_model_data attributes into the alps_data struct so that we don't need a unique table entry for every possible permutation of protocol version, flags, byte0/mask0, etc. Signed-off-by:

This patch adds support for the Cypress APA Smbus Trackpad type, which uses a modified register map that fits within the limitations of the smbus protocol. Devices that use this protocol include: CYTRA-116001-00 - Samsung Series 5 550 Chromebook trackpad CYTRA-103002-00 - Acer C7 Chromebook trackpad CYTRA-101003-00 - HP Pavilion 14 Chromebook trackpad Signed-off-by:

Investigating the following gesture highlighted two slight implementation errors with choosing which slots to report in which slot when multiple contacts are present: Action SGM AGM (MTB slot:Contact) 1. Touch contact 0 (0:0) 2. Touch contact 1 (0:0, 1:1) 3. Lift contact 0 (1:1) 4. Touch contacts 2,3 (0:2, 1:3) In step 4, slot 1 was not being cleared first, which means the same tracking ID was being used for reporting both the old contact 1 and the new contact 3. This could result in "drumroll", where the old contact 1 would appear to suddenly jump to new finger 3 position. Similarly, if contacts 2 & 3 are not detected at the same sample, step 4 is split into two: Action SGM AGM (MTB slot:contact) 1. Touch contact 0 (0:0) 2. Touch contact 1 (0:0, 1:1) 3. Lift contact 0 (1:1) 4. Touch contact 2 (0:2, 1:1) 5. Touch contact 3 (0:2, 1:3) In this case, there was also a bug. In step 4, when contact 1 moves from SGM to AGM and contact 2 is first reported in SGM, slot 0 was actually empty. So slot 0 can be used to report the new SGM (contact 0), immediately. Since it was empty, contact 2 in slot 0 will get a new tracking ID. Signed-off-by:

When removing the !S390 dependency from drivers/input/Kconfig a couple of drivers don't compile because they have a dependency on GENERIC_HARDIRQS. So add the missing dependencies.

Logic sets a value and then reads it back to make sure it worked and retries write on failures. Since read and write share a buffer, it needs to be set back up before writing though. Issue is not seen a lot because 1) it doesn't need to retry for a lot of tablets and 2) a lot of failures that need a retry are from an -ETIMEDOUT and hopefully buffer is not touched in this case. At least one user has shown logs with buffer being modified during -ETIMEDOUT case with linux 3.7 kernel. Signed-off-by:

On resume from suspend there is a possibility for multi-byte scancodes to be handled incorrectly. atkbd_reconnect disables the processing of scancodes in software by calling atkbd_disable, but the keyboard may still be active because no disconnect command was sent. Later, software handling is re-enabled. If a multi-byte scancode sent from the keyboard straddles the re-enable, only the latter byte(s) will be handled. In practice, this leads to cases where multi-byte break codes (ex. "e0 4d" - break code for right-arrow) are misread as make codes ("4d" - make code for numeric 6), leading to one or more unwanted, untyped characters being interpreted. The solution implemented here involves sending command f5 (reset disable) to the keyboard prior to disabling software handling of codes. Later, the command to re-enable the keyboard is sent only after we are prepared to handle scancodes. Signed-off-by:Shawn Nematbakhsh <shawnn@chromium.org> Signed-off-by:
