Add support for the 15'' MacBook Pro Retina. The keyboard is the same as recent models. The patch needs to be synchronized with the bcm5974 patch for the trackpad - as usual. Patch originally written by clipcarl (forums.opensuse.org). [rydberg@euromail.se: Amended mouse ignore lines] Signed-off-by:

Since commit 1c6c6952 ("genirq: Reject bogus threaded irq requests") threaded IRQs without a primary handler need to be requested with IRQF_ONESHOT, otherwise the request will fail. This patch adds the IRQF_ONESHOT to input drivers where it is missing. Not modified by this patch are those drivers where the requested IRQ will always be a nested IRQ (e.g. because it's part of an MFD), since for this special case IRQF_ONESHOT is not required to be specified when requesting the IRQ.

Keymaps used by drivers based on matrix-keymap facilities are arrays of unsigned shorts, not chars. Treating them otherwise produces corrupted keymaps. Reported-by:

Handle these offsets through static mapping and assign these mappings during run time. Tested on omap4430 sdp with 3.4-rc3. Tested on omap5430evm with 3.1-custom kernel.

This patch adds semi-MT support for ALPS v4 protocol touchpads. It is based on the work by Seth Forshee for ALPS v3 and v4 protocol support. Three packets are required to assemble and process the MT data. ST events are reported at once to avoid latency. If there were two contacts or more, report MT data instead of ST events. Thanks to Seth Forshee for providing most of the code, guidance and insight for producing this patch. Signed-off-by:

This driver adds support for the Synaptics NavPoint touchpad connected to a PXA27x SSP port in SPI slave mode. The device emulates a mouse; a tap or tap-and-a-half drag gesture emulates the left mouse button. For example, use the xf86-input-evdev driver for an X pointing device. Signed-off-by:

According to the standard count 0 is special - no IO should happen but we can check error conditions (device gone away, etc), and return 0 if there are no errors. We used to return -EINVAL instead and we also could return 0 if an event was "stolen" by another thread. Signed-off-by: -

When copy_to/from_user fails in the middle of transfer we should not report to the user that read/write partially succeeded but rather report -EFAULT right away, so that application will know that it got its buffers all wrong. If application messed up its buffers we can't trust the data fetched from userspace and successfully written to the device or if data read from the device and transferred to userspace ended up where application expected it to end. If serio_write() fails we still going to report partial writes if failure happens in the middle of the transfer. This is basically a revert of 7a0a27d2 and 4fa07711. Signed-off-by:

Main part of patch is adding support for a new Wacom MT touch packet and labels these devices using MTSCREEN type. Other items of interest: Delete some duplicate code in HID parsing for Y info since its already done in X path. In wacom_query_tablet_data(), only invoke the set report that requests tablets to send Wacom Touch packets for Finger interfaces. Mostly, this is to make code intent clear. Tested-by:
