  • With device tree support for regulators, its needed that the
    regulator_dev->dev device has the right of_node attached.
    To be able to do this add an additional parameter to the
    regulator_register() api, wherein the dt-adapted driver can
    then pass this additional info onto the regulator core.

  • The desc_id variable should not be a static variable.

    The rest of the code assumes the desc_id must less than TPSxxxxx_NUM_REGULATOR.
    If we set desc_id to be a static variable, checking the return value of
    rdev_get_id() may return error.

  • Change the interface used by set_voltage() to report the selected value
    to the regulator core in terms of a selector used by list_voltage().
    This allows the regulator core to know the voltage that was chosen
    without having to do an explict get_voltage(), which would be much more
    expensive as it will generally access hardware.

    In TPS6507x, depending on the status of DEFDCDC{2,3} pin either
    DEFDCDC{2,3}_LOW or DEFDCDC{2,3}_HIGH register needs to be read or
    programmed to change the output voltage.

    The current driver assumes DEFDCDC{2,3} pins are always tied low
    and thus operates only on DEFDCDC{2,3}_LOW register. This need
    not always be the case (as is found on OMAP-L138 EVM).

    Unfortunately, software cannot read the status of DEFDCDC{2,3} pins.
    So, this information is passed through platform data depending on
    how the board is wired.

  • Add mfd structure which refrences sub-driver initialization data. For example,
    for a giving hardware implementation, the voltage regulator sub-driver
    initialization data provides the mapping betten a voltage regulator and what
    the output voltage is being used for.

  • …it slab.h inclusion from percpu.h

    percpu.h is included by sched.h and module.h and thus ends up being
    included when building most .c files. percpu.h includes slab.h which
    in turn includes gfp.h making everything defined by the two files
    universally available and complicating inclusion dependencies.

    percpu.h -> slab.h dependency is about to be removed. Prepare for
    this change by updating users of gfp and slab facilities include those
    headers directly instead of assuming availability. As this conversion
    needs to touch large number of source files, the following script is
    used as the basis of conversion.

    http://userweb.kernel.org/~tj/misc/slabh-sweep.py

    The script does the followings.

    * Scan files for gfp and slab usages and update includes such that
    only the necessary includes are there. ie. if only gfp is used,
    gfp.h, if slab is used, slab.h.

    * When the script inserts a new include, it looks at the include
    blocks and try to put the new include such that its order conforms
    to its surrounding. It's put in the include block which contains
    core kernel includes, in the same order that the rest are ordered -
    alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
    doesn't seem to be any matching order.

    * If the script can't find a place to put a new include (mostly
    because the file doesn't have fitting include block), it prints out
    an error message indicating which .h file needs to be added to the
    file.

    The conversion was done in the following steps.

    1. The initial automatic conversion of all .c files updated slightly
    over 4000 files, deleting around 700 includes and adding ~480 gfp.h
    and ~3000 slab.h inclusions. The script emitted errors for ~400
    files.

    2. Each error was manually checked. Some didn't need the inclusion,
    some needed manual addition while adding it to implementation .h or
    embedding .c file was more appropriate for others. This step added
    inclusions to around 150 files.

    3. The script was run again and the output was compared to the edits
    from #2 to make sure no file was left behind.

    4. Several build tests were done and a couple of problems were fixed.
    e.g. lib/decompress_*.c used malloc/free() wrappers around slab
    APIs requiring slab.h to be added manually.

    5. The script was run on all .h files but without automatically
    editing them as sprinkling gfp.h and slab.h inclusions around .h
    files could easily lead to inclusion dependency hell. Most gfp.h
    inclusion directives were ignored as stuff from gfp.h was usually
    wildly available and often used in preprocessor macros. Each
    slab.h inclusion directive was examined and added manually as
    necessary.

    6. percpu.h was updated not to include slab.h.

    7. Build test were done on the following configurations and failures
    were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my
    distributed build env didn't work with gcov compiles) and a few
    more options had to be turned off depending on archs to make things
    build (like ipr on powerpc/64 which failed due to missing writeq).

    * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
    * powerpc and powerpc64 SMP allmodconfig
    * sparc and sparc64 SMP allmodconfig
    * ia64 SMP allmodconfig
    * s390 SMP allmodconfig
    * alpha SMP allmodconfig
    * um on x86_64 SMP allmodconfig

    8. percpu.h modifications were reverted so that it could be applied as
    a separate patch and serve as bisection point.

    Given the fact that I had only a couple of failures from tests on step
    6, I'm fairly confident about the coverage of this conversion patch.
    If there is a breakage, it's likely to be something in one of the arch
    headers which should be easily discoverable easily on most builds of
    the specific arch.

    drivers/regulator/tps65023-regulator: struct i2c_device_id is 32 bytes. The last of 1 is:

    FATAL: drivers/regulator/tps65023-regulator: struct i2c_device_id is not terminated with a NULL entry!

    This patch also fixes the GPL v2 licence string for both drivers.
