| * | | iio:light:stk3310: move device register to end of probeHartmut Knaack2015-07-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | iio_device_register should be the last operation during probe. Therefor move up interrupt setup code and while at it, change the check for invalid values of client->irq to be smaller than zero. Fixes: 3dd477acbdd1 ("iio: light: Add threshold interrupt support for STK3310") As the device_register makes the userspace interfaces of the device available it is possible for requests to come in before the probe sequence has finished. This can lead to unhandled interrupts and similar.

This is not the case here. Since the threshold is no signed value and only the magnitude is compared, IIO_EV_TYPE_MAG is what describes the behaviour of these devices, see the sysfs-bus-iio ABI Documentation.

During Linux suspend process, all the run time suspended devices are resumed and then suspended. This caused all sensors to power up and introduced delay in suspend time, when we introduced runtime PM for HID sensors. The opposite process happens during resume process. To fix this, we do powerup process of the sensors only when the request is issued from user (raw or tiggerred). In this way when runtime, resume calls for powerup it will simply return as this will not match user requested state. Note this is a regression fix as the increase in suspend / resume times can be substantial (report of 8 seconds on Len's laptop!)

Otherwise, writing to any of them will change the sampling frequency.

As consequences of this change, iio event directions have been switched and maximum proximity sensor reference values have also been adjusted in accordance with the real readings.

The normal flow of waking up devices in order to go into suspend (given the devices are normally suspended when not reading) to a regression in suspend time on some laptops (reports of an additional 8 seconds). Fix this by checking to see if a user action resulting in the wake up, and make it a null operation if it didn't. Note that for hid sensors, there is nothing useful to be done when moving into a full suspend from a runtime suspend so they might as well be left alone. * rochip_saradc: fix some missing MODULE_* data including the licence so that the driver does not taint the kernel incorrectly and can build as a module. * twl4030 - mark irq as oneshot as it always should have been. * inv-mpu - write formats for attributes not specified, leading to miss interpretation of the gyro scale channel when written. * Proximity ABI clarification. This had snuck through as a mess. Some drivers thought proximity went in one direction, some the other. We went with the most common option, documented it and fixed up the drivers going the other way. Fix for sx9500 included in this set. * ad624r - fix a wrong shift in the output data. * at91_adc - remove a false limit on the value of the STARTUP register applied by too small a type for the device tree parameter. * cm3323 - clear the bits when setting the integration time (otherwise we can only ever set more bits in the relevant field). * bmc150-accel - multiple triggers are registered, but on error were not being unwound in the opposite order leading to removal of triggers that had not yet successfully been registered (count down instead of up when unwinding). * tcs3414 - ensure right part of val / val2 pair read so that the integration time is not always 0. * cc10001_adc - bug in kconfig dependency. Use of OR when AND was intended.
