fdbde81bad pinctrl: mvebu: make bool drivers explicitly non-modular
None of the Kconfigs for any of these drivers are tristate, meaning
that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.
All drivers get the exact same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) dont use module.h
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

For the dove driver we explicitly disallow a driver unbind, since
that doesn't have a sensible use case anyway, and it allows us to
drop the ".remove" code for non-modular drivers.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

We deleted the MODULE_LICENSE etc. tags since all that information
is already contained at the top of the file in the comments.

     DT only shop for SuperH

9e05db29e2 pinctrl: mvebu: armada-370: align spi1 clock pin naming
Across all SoCs, even on Armada 370 for SPI0, the clock pin uses the
'sck' subname and not 'clk', so this commit adjusts the code and
documentation accordingly.

Since this commit only changes the subname, DT backward compatibility
is not affected.

a361cbc575 pinctrl: mvebu: armada-{370,xp}: normalize ethernet txclkout pins
This commit normalizes the naming of the Ethernet txclkout pin to be
the same accross Marvell SoCs. It is worth mentioning that the DT
binding documentation of the Armada XP was wrong for MPP12: it said
the function was ge1(txd0), while it is in fact ge1(txclkout). It is
however not really a fix worth sending to stable since it does not
change the behavior, and the driver itself was correct.

Since only the subnames are changed, DT backward compatibility is not
affected.

dae5597f25 pinctrl: mvebu: armada-{370,375,38x,39x,xp}: normalize TDM pins
This commit normalizes the naming of the TDM pins accross the
different Marvell SoCs. Mainly it consists in:

 * Removing the 'n' from signal names: 'intn' becomes 'int' and 'rstn'
   becomes 'rst'

 * Renaming the main name 'tdm2c' to 'tdm' on Armada 38x.

 * Change the main name 'tdm-1' to 'tdm' for one of the pins of the
   Armada XP

The last two changes affect DT compatibility, but since the TDM
interface is nowhere near being supported in mainline, it should not
be considered to be a serious problem at this point.

7bd6a26db6 pinctrl: mvebu: armada-{370,375,38x,39x}: normalize dev pins
This commit modifies the definition of the Device Bus interface pins
to be consistent accross SoCs. Especially, it removes the 'n'
indicators that we don't encode in the subnames of pins:

   'dev(wen0)' becomes 'dev(we0)'
   'dev(wen1)' becomes 'dev(we1)'
   'dev(oen)' becomes 'dev(oe)'
   etc.

In addition, it fixes the Armada 375 DT binding documentation, which
forgot to document the 'dev' function for MPP46, MPP57 and MPP63.

Since only the subnames are changed, this commit does not affect DT
compatibility.

This change removes the use of __devinit, __devexit_p, __devinitdata,

Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

06763c741b pinctrl: mvebu: move to its own directory
Like the spear platform, the mvebu platform has multiple files: one
core file, and then one file per SoC family. More files will be added
later, as support for mach-orion5x and mach-mv78xx0 SoCs is added to
pinctrl-mvebu. For those reasons, having a separate subdirectory,
drivers/pinctrl/mvebu/ makes sense, and it had already been suggested
by Linus Wallej when the driver was originally submitted.
