* HID: wiimote: Add MAINTAINERS entryDavid Herrmann2011-09-07
| | | | | | | | Add entry to MAINTAINERS and also bump version level as the core driver is feature complete now. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Read wiimote battery charge levelDavid Herrmann2011-09-07
| | | | | | | | | This registers a power_supply device for every remote to retrieve the current battery charge level. Since this information is not sent by the wiimote continously, we need to explicitely request it.

* HID: wiimote: Add status requestDavid Herrmann2011-09-07
| | | | | | | | The wiimote does not send status reports continuously so this adds a helper function to request a status report and parses the battery charge level. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Initialize IR cam on requestDavid Herrmann2011-09-07

* HID: wiimote: Add IR initializerDavid Herrmann2011-09-07
| | | | | | | | The wiimote IR cam needs a fairly complex initialization sequence. This adds a helper function that performs IR initialization synchronously. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Add write-register helpersDavid Herrmann2011-09-07
| | | | | | | | Add helpers to synchronously write registers of the wiimote. This is heavily used by initialization functions for wiimote peripherals. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Helper functions for synchronous requestsDavid Herrmann2011-09-07
| | | | | | | | | | | | | | | | | To initialize wiimote peripherals, the stream to the wiimote must be held exclusively by the initializer, otherwise the initialization will fail. Many initializations require multiple memory requests to be sent synchronously so we need a way to lock the stream and release it when we are done. This adds several helper functions which allow to lock the stream, then send requests, wait for the answers and release the stream again. When holding the lock, the function may sleep and interrupted by signals. Also it returns after a short timeout so userspace shouldn't notice long delays.

* HID: wiimote: Add register/eeprom memory supportDavid Herrmann2011-09-07
| | | | | | | | | | | | | The wiimote allows direct access to its memory mapped registers and internal eeprom. This adds support to access this memory and handle memory events. There are two macros which wrap up the memory access functions to avoid accidentally overwriting sensitive eeprom data because a boolean value was wrongly set.

* HID: wiimote: Add missing extension DRM handlersDavid Herrmann2011-09-07
| | | | | | | | | | | If an extension is connected the wiimote may report data though DRMs that contain extension data. This adds handlers for these DRMs but discards extension data since we do not support it, yet. It prints a warning to kernel log if an unhandled report is catched. Since we handle all requests now, this should never happen, though. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Parse IR dataDavid Herrmann2011-09-07
| | | | | | | | | | | Parse IR data and report it to IR input-device. IR data is sent in 3 different formats, but we only support the basic format as there is no way to send the additional information to userspace. All three formats are compatible with the basic IR data format so we need only one parser. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Add IR input deviceDavid Herrmann2011-09-07
| | | | | | | | | | | | | | The IR cam of the wiimote reports 4 trackable lights as absolute values. Since we can turn the IR cam on and off, we register a separate input device so we can react on open/close callbacks to save wiimote battery power when IR cam is not needed. The cam can be in four states: off, basic, extended and full The DRM chooser automatically selects a proper DRM that includes all required IR data so no information is lost.

* HID: wiimote: Parse accelerometer dataDavid Herrmann2011-09-07
| | | | | | | | | | | | | | | | | Add parser functions for accelerometer data reported by the wiimote. The data is almost always reported in the same format, so we can use a single handler. However, an own handler function is created for each DRM-mode because when IR and extension support is added, each of them is parsed differently. Also set the appropriate DRM including accelerometer data on DRM requests to actually retrieve the accelerometer data. Data is reported to userspace as ABS_RX/Y/Z values. The values are between -500 and 500 and 0 means no acceleration. See also userspace xwiimote library for data parsing.

* HID: wiimote: Add accelerometer input deviceDavid Herrmann2011-09-07
| | | | | | | | | | Add new input device for every wiimote which is used to report accelerometer data to userspace. Only if the input device is currently open, we make the wiimote send accelerometer data. This saves a whole lot of energy on the wiimote if an application is only interested in button input reports.

* HID: wiimote: Add force-feedback supportDavid Herrmann2011-09-07
| | | | | | | | | | | | The wiimote has a single rumble motor. This adds force feedback support for wiimote devices with FF_RUMBLE. The rumble motor is very simple and only supports an on/off switch so no complex ff-effects are supported. This also removes the event callback that was registered before but unused. The ff-device overwrites this callback, anyway. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
* HID: wiimote: Support rumble deviceDavid Herrmann2011-09-07
| | | | | | | | | | This adds support for the wiimote's rumble device. Every output report can enable and disable the rumble motor. Hence, every output report must look up our new RUMBLE flag and make sure that it does not unintentionally toggle the rumble motor.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Queue idling is used for the anticipation of immediate sequencial I/O's but md_super_write() is a kind of one- shot operation, coupled with md_super_wait(), so the idling in this case will be just a waste of time. Specifying REQ_NOIDLE prevents it. Instead of adding the flag to submit_bio() directly, use pre-defined macro WRITE_FLUSH_FUA.

However, pm_runtime_get_sync can return a positive number which does not suggest an error has occurred. This is problematic for two reasons: 1. The function will needlessly bail out without decrementing back the runtime PM reference counter. 2. wl1271_power_on only checks if wl1271_power_on return value is negative. This means that wl1271_power_on will continue even if wl1271_sdio_power_on bailed out. As a result, sdio transactions will be initiated without properly enabling the sdio function and claiming the host. This could even lead to a kernel panic.

In addition, it has several implementation issues that prevent it from working correctly: 1. wl1271_tm_cmd_configure relies on wl->chip.id being set. However, since the device was not necessarily booted by the time the function is called, wl->chip.id will be initialized to 0. 2. The NVS file is fetched by calling request_firmware() before it is possible to push an NVS file. 3. The maximum allowed size of nl binary payloads is not sufficient for pushing NVS files. 4. Pushing 128x NVS files will always fail due to a bug in the validation code. 5. In case the pushed NVS file is found invalid, the mutex will be kept locked and the nvs member will become a dangling pointer. Since this feature is not being used, remove it completely instead of fixing it. Signed-off-by: Ido Yariv <ido@wizery.com> Acked-by: Luciano Coelho <coelho@ti.com> Signed-off-by: John W.

As a result we free memory early, and get crash when unplugging usb dongle.

Disconnecting a device is a normal thing to happen so it's no big deal that usb_submit_urb() returns -ENODEV. The simplest way to get rid of these errors is to stop treating that return as an error. Trivial, actually. While we're at it, add comments to be explicit about the reasons we're not complaining about -EPERM and -ENODEV.

There is no software code, nor needs to get/set real CTS signal. But, when turning CRTSCTS on through termios, uart_set_termios() in serial_core.c checks CTS, and stops TX if it is inactive at the moment. Because sci_get_mctrl() returns a fixed value DTR|RTS|DSR but CTS, the sequence open -> set CRTSCTS -> write hit the case and stop working, no more outputs. This patch makes sci_get_mctrl() report CTS in addition. Signed-off-by: Takashi YOSHII <takashi.yoshii.zj@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
