* ENGR00318936-2 input: keyboard: imx: remove usless release interrupt enabled ↵Robin Gong2014-06-19
| | | | | | | | | | code Remove useless code for release interrupt enabled, because we check status by timer rather than release interrupt. Remove the code which may disable depress interrupt. Also make sure enable depress interrupt in suspend function. Signed-off-by: Robin Gong <b38343@freescale.com>
* ENGR00318936-1 input: keyboard: imx: add pm_stay_awake and pm_relaxRobin Gong2014-06-19
| | | | | | | | | | There is a small window after system suspend but timer scan function didn't finish timely, in this case, system enter suspend without kpp interrupt enabled and failed to resume back if key depressed.We add pm_stay_awake and pm_relax to make sure system suspend flow abort in this case.

| | | | | | | | | | | | | | | | | | | | evbug will open the mma8450 on i.MX6SL_EVK and mma8450 will work in 2G mode by default. That is the reason why mma8450 logs will be printed out. The main changes is below: * Remove the open(), close() hook out of the drivers. The open() and close() hook in input framwork is defined as void type. It isn't strictly safe in logic when some error happends. So remove them out. * Modify the mma8450 to standby mode by default. It will be more power saving and there would be no log printing out after booting up. * Provide the sys interface to modify the mma8450 work modes. Then the higher layer can modify the the mma8450 work mode via the interface. It would be much safer.There would be a sclaemode interface in the folder of /sys/devices/soc0/soc.1/2100000.aips-bus/21a0000.i2c/i2c-0/0-001c/scalemode User can use cat to read the current scalemode and echo to write.

* Input: usbtouchscreen - separate report and transmit buffer size handlingChristian Engelmayer2013-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 4ef38351d770cc421f4a0c7a849fd13207fc5741 upstream. This patch supports the separate handling of the USB transfer buffer length and the length of the buffer used for multi packet support. For devices supporting multiple report or diagnostic packets, the USB transfer size is now limited to the USB endpoints wMaxPacketSize - otherwise it defaults to the configured report packet size as before. This fixes an issue where event reporting can be delayed for an arbitrary time for multi packet devices. For instance the report size for eGalax devices is defined to the 16 byte maximum diagnostic packet size as opposed to the 5 byte report packet size. In case the driver requests 16 byte from the USB interrupt endpoint, the USB host controller driver needs to split up the request into 2 accesses according to the endpoints wMaxPacketSize of 8 byte. When the first transfer is answered by the eGalax device with not less than the full 8 byte requested, the host controller has got no way of knowing whether the touch controller has got additional data queued and will issue the second transfer. If per example a liftoff event finishes at such a wMaxPacketSize boundary, the data will not be available to the usbtouch driver until a further event is triggered and transfered to the host. From user perspective the BTN_TOUCH release event in this case is stuck until the next touch down event.

| | | | | | | | | | | | | | | | | | | | | commit bcd2623073e98f69f84720308db0b142c4da0bd6 upstream. There is plenty of consumer hardware (e.g., mac books) that does not use AT keyboards or PS/2 mice. It therefore makes sense for distro kernels to build the related drivers as modules to avoid loading them on hardware that does not need them. As such, these options should no longer be protected by EXPERT. Moreover, building these drivers as modules gets rid of the following ugly error during boot: [ 2.337745] i8042: PNP: No PS/2 controller found. Probing ports directly.

* Input: evdev - fall back to vmalloc for client event bufferDaniel Stone2013-12-04
| | | | | | | | | | | | | | | | | | | commit 92eb77d0ffbaa71b501a0a8dabf09a351bf4267f upstream. evdev always tries to allocate the event buffer for clients using kzalloc rather than vmalloc, presumably to avoid mapping overhead where possible. However, drivers like bcm5974, which claims support for reporting 16 fingers simultaneously, can have an extraordinarily large buffer. The resultant contiguous order-4 allocation attempt fails due to fragmentation, and the device is thus unusable until reboot. Try kzalloc if we can to avoid the mapping overhead, but if that fails, fall back to vzalloc.

* HID: Correct the USB IDs for the new Macbook Air 6Henrik Rydberg2013-09-26
| | | | | | | | | | | | | | | | | | commit 8c89cc17b91992845bd635813cd162fe8dfcec6e upstream. A recent patch (9d9a04ee) added support for the new machine, but got the sequence of USB ids wrong. Reports from both Ian and Linus T show that the 0x0291 id is for ISO, not ANSI, which should have the missing number 0x0290. This patchs moves the three numbers accordingly, fixing the problem.

The June 2013 Macbook Air (13'') has a new trackpad protocol; four new values are inserted in the header, and the mode switch is no longer needed. This patch adds support for the new devices.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In summary, the symptom is intermittent key events lost after resume on some machines with synaptics touchpad (seems this is synaptics _only_), and key events loss is due to serio port reconnect after psmouse sync lost. Removing psmouse and inserting it back during the suspend/resume process is able to work around the issue, so the difference between psmouse_connect() and psmouse_reconnect() is the key to the root cause of this problem. After comparing the two different paths, synaptics driver has its own implementation of synaptics_reconnect(), and the missing psmouse_probe() seems significant, the patch below added psmouse_probe() to the reconnect process, and has been verified many times that the issue could not be reliably reproduced. There are two PS/2 commands in psmouse_probe(): 1. PSMOUSE_CMD_GETID 2. PSMOUSE_CMD_RESET_DIS Only the PSMOUSE_CMD_GETID seems to be significant. The PSMOUSE_CMD_RESET_DIS is irrelevant to this issue after trying several times. So we have only implemented this patch to issue the PSMOUSE_CMD_GETID so far.

This is separate from the GPIO-driven matrix keypad binding, and unfortunately incompatible, since that uses row-gpios/col-gpios for the row and column counts. So the easiest option here is to provide a function for non-GPIO drivers to use to decode the binding. Note: We could in fact create an entirely separate structure to hold these two fields, but it does not seem worth it, yet. If we have more parameters then we can add this, and then refactor each driver to hold such a structure.
