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. Acked-by:

This is a follow up patches after adding i2c mux adapter for bypass mode. Potentially many different types of sensor can be attached to INVMPU6XXX device, which can be connected to main cpu i2c bus in bypass mode. Why do we need this? The system ACPI table entry will consist of only one device for INV6XXX, assuming that this driver will handle all connected sensors. That is not true for the Linux driver. There are bunch of IIO drivers for each sensors, hence we created a mux on this device. So to load these additional drivers, we need to create i2c devices for them in this driver using this mux adapter. There are multiple options: 1. Use the auto detect feature, this needs a new i2c class for the adapter as the existing HWMON class is not acceptable. Also the autodetect has overhead of executing detect method for each matching class of adapters. This is a simple implementation. This option was previously submitted with not a happy feedback. 2. Option is use ACPI magic and parse the configuration data. What we need to create a i2c device at a minimum is address and a name. Address can be obtained for secondary device in more or less in a standard way from using _CRS element. But there is no name. To get name we need to process proprietary vendor data. Not having name is not fun, as you have to create device using the device name of INVN6XXXX, respecting driver duplicate name space restriction. Also each client driver needs to have this name in the id table. Since multiple driver can be loaded, the driver should be able to detect its presence and gracefully exit for the other client driver to take it over. So we use two step process: - Use DMI to id platform and parse propritery data. This is not uncommon for many x86 platform specific driver. We will get both name and address. The change created necessary infrastructure to add more properitery vendor data parsing. - If DMI match fails, then create device on INV6XXX-client (we can't create with same name as INV6XXX as it will cause duplicate name and driver model will reject.) With this each client sensor driver which needs to get attached via INV6XXXX, need this name in the id table and detect the physical presence of sensor in probe and exit if not found. Signed-off-by:

After UAPI header file split [1] all user-kernel interfaces were placed under include/uapi/. This patch moves IIO user specific API from: * include/linux/iio/events.h => include/uapi/linux/iio/events.h * include/linux/types.h => include/uapi/linux/types.h Now there is no need for nasty tricks to compile userspace programs (e.g iio_event_monitor). Just installing the kernel headers with make headers_install command does the job. [1] http://lwn.net/Articles/507794/Signed-off-by:

Commit 8eb23b9f ("sched: Debug nested sleeps") added code to report on nested sleep conditions, which we generally want to avoid because the inner sleeping operation can re-set the thread state to TASK_RUNNING, but that will then cause the outer sleep loop not actually sleep when it calls schedule. However, that's actually valid traditional behavior, with the inner sleep being some fairly rare case (like taking a sleeping lock that normally doesn't actually need to sleep). And the debug code would actually change the state of the task to TASK_RUNNING internally, which makes that kind of traditional and working code not work at all, because now the nested sleep doesn't just sometimes cause the outer one to not block, but will cause it to happen every time. In particular, it will cause the cardbus kernel daemon (pccardd) to basically busy-loop doing scheduling, converting a laptop into a heater, as reported by Bruno Prémont. But there may be other legacy uses of that nested sleep model in other drivers that are also likely to never get converted to the new model. This fixes both cases: - don't set TASK_RUNNING when the nested condition happens (note: even if WARN_ONCE() only _warns_ once, the return value isn't whether the warning happened, but whether the condition for the warning was true. So despite the warning only happening once, the "if (WARN_ON(..))" would trigger for every nested sleep. - in the cases where we knowingly disable the warning by using "sched_annotate_sleep()", don't change the task state (that is used for all core scheduling decisions), instead use '->task_state_change' that is used for the debugging decision itself. (Credit for the second part of the fix goes to Oleg Nesterov: "Can't we avoid this subtle change in behaviour DEBUG_ATOMIC_SLEEP adds?" with the suggested change to use 'task_state_change' as part of the test) Reported-and-bisected-by:

Merge tag 'iio-for-3.20b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-testing Jonathan writes: Second round of IIO new drivers, functionality and cleanups for the 3.20 cycle. New drivers and device support: * Capella cm3232 ambient light sensor driver. * Freescale MMA9553 pedometer and activity monitor. Note this involved a refactor of the mma9551 driver to pull out shared elements. * Samsung sensor hub (as used in the galaxy gear 2 watch) Core support and initial drivers (gyro and accelerometer) more to follow. An additional fix was applied on top of this for a build issue thrown up by the autobuilders on some platforms. * Cosmic Circuits 10001 ADC driver * Qualcomm SPMI PMIC voltage ADC driver (current adc merged a while back). * Add binding for AK8963 (in capitals) as unfortunately there are bios' out there not using lower case. New functionality * Add newe operating mode to the core to allow for non triggered software buffers. This is mostly semantics as previously drivers just claimed they had a hardware buffer (when they didn't). * Add distance channel type. * Add energy channel type. * Add velocity channel type and IIO_MOD_ROOT_SUM_SQUARED (i.e. speed when our channel type is velocity). * Add _debounce_count and _debounce_time filter attributes. Only really make sense for counting types of measurements. First use is for avoiding miss detection of steps prior to walking. * Add change event type. This replaces the briefly present INSTANCE type (which hadn't gained any users). It is more generic as it allows for events say every 10 steps rather than every step. * Add _calibweight attributes to the ABI (and core support). Used by activity monitors to estimate energy use. Can imagine there will be other uses for this one. Driver new functionality * mma9551 gains runtime pm support. * hid-sensors gain PM support. Cleanup * Change calibheight unit to m from cm. As there are no prior users and this was inconsistent with other distance units, it makes sense to fix it before hte mma9553 driver which uses it. * mpu6050 cleanups and devm_ use. * as3935 switch over to PM ops. * Fix a few format strings for signed vs unsigned. * Fix tcs3414 missindentation * Typo in industrialio-event * Stop requiring IIO_TRIGGER for IIO_KFIFO_BUF as we have drivers that don't need it. No one is quite sure why that dependency was there and it seems to not matter.
