Staging patches for 3.19-rc1

Browse Source 
Here's the big staging tree pull request for 3.19-rc1.
 
 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.
 
 All of these patches have been in linux-next for a while with no
 reported issues.

Qualcomm's SPMI PMIC current ADC
QPNP PMIC current ADC (IADC) provides interface to clients to read current.
A 16 bit ADC is used for current measurements. IADC can measure the current
through an external resistor (channel 1) or internal (built-in) resistor
(channel 0). When using an external resistor it is to be described by
qcom,external-resistor-micro-ohms property.
IADC node:
- compatible:
Usage: required
Value type: <string>
Definition: Should contain "qcom,spmi-iadc".
- reg:
Usage: required
Value type: <prop-encoded-array>
Definition: IADC base address and length in the SPMI PMIC register map
- interrupts:
Usage: optional
Value type: <prop-encoded-array>
Definition: End of ADC conversion.
- qcom,external-resistor-micro-ohms:
Usage: optional
Value type: <u32>
Definition: Sense resister value in micro Ohm.
If not defined value of 10000 micro Ohms will be used.
Example:
/* IADC node */
pmic_iadc: iadc@3600 {
compatible = "qcom,spmi-iadc";
reg = <0x3600 0x100>;
interrupts = <0x0 0x36 0x0 IRQ_TYPE_EDGE_RISING>;
qcom,external-resistor-micro-ohms = <10000>;
#io-channel-cells = <1>;
};
/* IIO client node */
