    Pull staging driver updates from Greg KH:
    "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"

    Pull driver core update from Greg KH:
    "Here's the set of driver core patches for 3.19-rc1.

    They are dominated by the removal of the .owner field in platform
    drivers. They touch a lot of files, but they are "simple" changes,
    just removing a line in a structure.

    Other than that, a few minor driver core and debugfs changes. There
    are some ath9k patches coming in through this tree that have been
    acked by the wireless maintainers as they relied on the debugfs
    changes.

    Everything has been in linux-next for a while"

    After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is
    selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks

    CONFIG_PM.

    drivers/iio/.

    Currently, we get the new GSEL bits by OR-ing the old values
    with the new ones. This only works first time when the old
    values are 0.

    Startup:
    * GSEL0 = 0, GSEL1 = 0

    Set range to 4G: (GSEL0 = 1, GSEL1 = 0)
    * GSEL0 = 0 | 1 = 1
    * GSEL1 = 0 | 0 = 0
    * correct

    Change range to 2G: (GSEL0 = 0, GSEL1 = 0)
    * GSEL0 = 1 | 0 = 1
    * GSEL1 = 0 | 0 = 0
    * wrong, GSEL0 should be 0

    This has the nice effect that we can use the full scale range,
    exported in in_accel_scale_available.

    * Move exynos driver over to syscon for PMU register access.

    Cleanups, fixes for new drivers
    * lis3l02dq drop an unneeded else.

    Because IIO_EV_DIR_* are not bitmasks but enums,
    IIO_EV_DIR_RISING | IIO_EV_DIR_FALLING is not equal
    with IIO_EV_DIR_EITHER.

    This could lead to potential misformatted sysfs attributes
    like:
    * in_accel_x_thresh_(null)_en
    * in_accel_x_thresh_(null)_period
    * in_accel_x_thresh_(null)_value

    or even memory corruption.

    According to the datasheet and as defined in struct bmp280_comp_press, dig_p1 is
    of type u16, while dig_p2 to dig_p9 are of type s16. In
    bmp280_read_compensation_press(), values read from the device were treated as
    the wrong type.
    In bmp280_read_press() the fractional part of the measured pressure is
    calculated wrong. A better way is to use *val for the raw pressure and *val2 for
    the quotient and let the core do the proper conversion using IIO_VAL_FRACTIONAL.

    The ADC on exynos7 is quite similar to ADCv2. The differences are as
    follows:
    - exynos7-adc has 8 input channels (as against 10 in ADCv2).
    - exynos7 does not include an ADC PHY control register.
    - Some ADC_CON2 register bits being used in ADCv2 are listed as
    reserved in exynos7-adc. This results in a different init_hw
    function for exynos7.
