We continued to delete more lines than were added, always a good thing, but not at a huge rate this release, only about 70k lines removed overall mostly from removing the horrid bcm driver. Lots of normal staging driver cleanups and fixes all over the place, well over a thousand of them, the shortlog shows all the horrid details. The "contentious" thing here is the movement of the Android binder code out of staging into the "real" part of the kernel. This is code that has been stable for a few years now and is working as-is in the tens of millions of devices with no issues. Yes, the code is horrid, and the userspace api leaves a lot to be desired, but it's not going to change due to legacy issues that we have no control over. Because so many devices and companies rely on this, and the code is stable, might as well promote it out of staging. This was all discussed at the Linux Plumbers conference, and everyone participating agreed that this was the best way forward. There is work happening to replace the binder code with something new that is happening right now, but I don't expect to see the results of that work for another year at the earliest. If that ever happens, and Android switches over to it, I'll gladly remove this version. As for maintainers, I'll be glad to maintain this code, I've been doing it for the past few years with no problems. I'll send a MAINTAINERS entry for it before 3.19-final is out, still need to talk to the Google developers about if they are willing to help with it or not, last I checked they were, which was good.

This (rather late) set consists only of fixes to patches earlier in the cycle or minor fixes for other problems (such as randconfig build issues picked up by Arnd). I've included the general minor fixes here as it is very late in the current cycle and they can all wait for the merge window. * Recent change to hid-sensors introduced a possible infinite loop due to a typo. In the same series, a report interval unit read was added but in the case where the hardware doesn't support it a value of 0 would lead to some nasty issues. The patch sets it to the specified default of msecs. * Anon inodes were used by IIO without being explicitly selected. This has been true for a long time so it clearly only effects rather unusual configurations (rand configs) * at91 requires the input subsytem but this wasn't explicity in the Kconfig. * A couple of parts supported by the max1363 driver were using the wrong iio_chan_spec arrays and hence would missreport their bit depths. This has been there a long time and was never right so isn't a regression.

| * | iio:adc: Add Xilinx XADC driverLars-Peter Clausen2014-03-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx. The XADC has a DRP interface for communication. Currently two different frontends for the DRP interface exist. One that is only available on the ZYNQ family as a hardmacro in the SoC portion of the ZYNQ. The other one is available on all series 7 platforms and is a softmacro with a AXI interface. This driver supports both interfaces and internally has a small abstraction layer that hides the specifics of these interfaces from the main driver logic. The ADC has a couple of internal channels which are used for voltage and temperature monitoring of the FPGA as well as one primary and up to 16 channels auxiliary channels for measuring external voltages. The external auxiliary channels can either be directly connected each to one physical pin on the FPGA or they can make use of an external multiplexer which is responsible for multiplexing the external signals onto one pair of physical pins. The voltage and temperature monitoring channels also have an event capability which allows to generate a interrupt when their value falls below or raises above a set threshold. Buffered sampling mode is supported by the driver, but only for AXI-XADC since the ZYNQ XADC interface does not have capabilities for supporting buffer mode (no end-of-conversion interrupt). If buffered mode is supported the driver will register two triggers. One "xadc-samplerate" trigger which will generate samples with the configured samplerate. And one "xadc-convst" trigger which will generate one sample each time the CONVST (conversion start) signal is asserted.

* iio: ti_am335x_adc: Add continuous sampling supportZubair Lutfullah2013-09-21
| | | | | | | | | | | | | | | | | | | | | | | | Previously the driver had only one-shot reading functionality. This patch adds continuous sampling support to the driver. Continuous sampling starts when buffer is enabled. HW IRQ wakes worker thread that pushes samples to userspace. Sampling stops when buffer is disabled by userspace. Patil Rachna (TI) laid the ground work for ADC HW register access. Russ Dill (TI) fixed bugs in the driver relevant to FIFOs and IRQs. I fixed channel scanning so multiple ADC channels can be read simultaneously and pushed to userspace. Restructured the driver to fit IIO ABI. And added INDIO_BUFFER_HARDWARE mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GPADC is general purpose ADC found on TWL6030, and TWL6032 PMIC, known also as Phoenix and PhoenixLite. The TWL6030 and TWL6032 have GPADC with 17 and 19 channels respectively. Some channels have current source and are used for measuring voltage drop on resistive load for detecting battery ID resistance, or measuring voltage drop on NTC resistors for external temperature measurements. Some channels measure voltage, (i.e. battery voltage), and have voltage dividers, thus, capable to scale voltage. Some channels are dedicated for measuring die temperature. Some channels are calibrated in 2 points, having offsets from ideal values kept in trim registers. This is used to correct measurements. The differences between GPADC in TWL6030 and TWL6032: - 10 bit vs 12 bit ADC; - 17 vs 19 channels; - channels have different purpose(i.e. battery voltage channel 8 vs channel 18); - trim values are interpreted differently.

Then the rest is mostly tiny cleanups and fixes, among which we have Mark's wm5xxx and wm8xxx patchset." Far amount of annoying but largely trivial conflicts.
