iio: bmg160: IIO_BUFFER and IIO_TRIGGERED_BUFFER are required

2015-09-21T17:05:27Z

commit 06d2f6ca5a38abe92f1f3a132b331eee773868c3 upstream. This patch adds selects for IIO_BUFFER and IIO_TRIGGERED_BUFFER. Without IIO_BUFFER, the driver does not compile.

Jonathan writes: The usual mixed bag of fixes for IIO in the 4.1 cycle. Second version of this pull request as a small fix to a fix turned up before Greg pulled it for a cc10001 patch near the top of the tree. One core fix * Set updated for a iio kfifo was incorrectly set to false during a failed update, resulting in atttempts to repeat the failed operation appearing to succeed. This time I've decided to list the driver fixes in alphabetical order rather than 'randomly'. * axp288_adc - a recent change added a check for valid info masks when reading channels from consumer drivers. * bmp280 - temperature compensation was failing to read the tfine value, hence causing a temperature of 0 to always be returned and incorrect presure measurements. * cc10001 - Fix channel number mapping when some channels are reserved for remote CPUs. Fix an issue with the use of the power-up/power-down register (basically wrong polarity). Fix an issue due to the missinterpretting the return value from regulator_get_voltage. Add a delay before the start bit as recommended for the hardware to avoid data corruption. * hid pressure - fix channel spec of modfiied, but no modifier (which makes no sense!) * hid proximity - fix channel spec of modified, but no modifier (which makes no sense!). Fix a memory leak in the probe function. * mcp320x - occasional incorrect readings on dma using spi busses due to cacheline corruption. Fixed by forcing ___cacheline_aligned for the buffers. * mma9551 - buffer overrun fix (miss specified maximum length of buffers) * mma9553 - endian fix on status message. Add an enable element for activity channel. Input checking for activity period to avoid rather unpredictable results. * spmi-vadc - fix an overflow in the output value normalization seen on some boards. * st-snesors - oops due to use of a mutex that is not yet initialized during probe. * xilinx adc - Some wrong register addresses, a wrong address for vccaux channel, incorrect scale on VREFP and incorrect sign on VREFN.

iio:st_sensors: Fix oops when probing SPI devices

2015-04-26T17:24:08Z

In SPI mode the transfer buffer is locked with a mutex. However this mutex is only initilized after the probe, but some transfer needs to be done in the probe. To fix this bug we move the mutex initialization at the beginning of the device probe. Signed-off-by: Alban Bedel Acked-by: Denis Ciocca Cc: Signed-off-by: Jonathan Cameron

Pull HID updates from Jiri Kosina: - quite a few firmware fixes for RMI driver by Andrew Duggan - huion and uclogic drivers have been substantially overlaping in functionality laterly. This redundancy is fixed by hid-huion driver being merged into hid-uclogic; work done by Benjamin Tissoires and Nikolai Kondrashov - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg - Some of the quirks, that got separated into individual drivers, have historically had EXPERT dependency. As HID subsystem matured (as well as the individual drivers), this made less and less sense. This dependency is now being removed by patch from Jean Delvare - Logitech lg4ff driver received a couple of improvements for mode switching, by Michal Malý - multitouch driver now supports clickpads, patches by Benjamin Tissoires and Seth Forshee - hid-sensor framework received a substantial update; namely support for Custom and Generic pages is being added; work done by Srinivas Pandruvada - wacom driver received substantial update; it now supports i2c-conntected devices (Mika Westerberg), Bamboo PADs are now properly supported (Benjamin Tissoires), much improved battery reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng) - small assorted fixes and device ID additions * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid: (68 commits) HID: sensor: Update document for custom sensor HID: sensor: Custom and Generic sensor support HID: debug: fix error handling in hid_debug_events_read() Input - mt: Fix input_mt_get_slot_by_key HID: logitech-hidpp: fix error return code HID: wacom: Add support for Cintiq 13HD Touch HID: logitech-hidpp: add a module parameter to keep firmware gestures HID: usbhid: yet another mouse with ALWAYS_POLL HID: usbhid: more mice with ALWAYS_POLL HID: wacom: set stylus_in_proximity before checking touch_down HID: wacom: use wacom_wac_finger_count_touches to set touch_down HID: wacom: remove hardcoded WACOM_QUIRK_MULTI_INPUT HID: pidff: effect can't be NULL HID: add quirk for PIXART OEM mouse used by HP HID: add HP OEM mouse to quirk ALWAYS_POLL HID: wacom: ask for a in-prox report when it was missed HID: hid-sensor-hub: Fix sparse warning HID: hid-sensor-hub: fix attribute read for logical usage id HID: plantronics: fix Kconfig default HID: pidff: support more than one concurrent effect ...

IIO: Add support for L3GD20H gyroscope

iio: gyro: itg3200: add suspend/resume support.

2015-03-09T14:54:42Z

Unless we put the device to sleep when not it use, it wastes 6mA. If the device is asleep on probe, the 'id' register sometimes mis-reads - so reset first. If the device responds at all a command sent to the address, it is almost certainly the correct device already.

iio: fix drivers that check buffer->scan_mask

2015-03-07T19:17:07Z

If the in-kernel push interface is used we may have a different masks on the device buffer and the kernel buffer and in this case the device should generate data for the reunion of the buffers, which is available at indio_dev->active_scan_mask. Compiled tested only except for bmc150-accel which was tested at runtime with the hardware. Signed-off-by: Octavian Purdila Cc: Signed-off-by: Jonathan Cameron

HID: hid-sensor-hub: Extend API for async reads

2015-02-23T14:16:37Z

Add additional flag to read in async mode. In this mode the caller will get reply via registered callback for capture_sample. Callbacks can be registered using sensor_hub_register_callback function. The usage id parameter of the capture_sample can be matched with the usage id of the requested attribute. Signed-off-by: Srinivas Pandruvada Acked-by: Jonathan Cameron Signed-off-by: Jiri Kosina
