UART0 had a hack that enabled its pins on init and put it to

This adds a scratch pin control interface to the Nomadik pinctrl
driver, and defines the pins and groups in the DB8500 ASIC. We
define GPIO ranges to cover the pins exposed. The DB8500 has
more pins than this but we restrict the driver to the pins that
can be controlled from the combined GPIO and pin control hardware
to begin with.

ChangeLog v1->v2:
- Base on the latest pinctrl development from
  pinctrl-mergebase-20120418 so we can get rid of legacy
  group count mechanism. Also drop the range checks for group
  index, this is handled by the core now.

This platform has been obsoleted and was only available inside of
ST-Ericsson, no users of this code are left in the world. This
deletes the core U5500 support entirely in the same manner as the
obsoleted U8500 silicon was previously deleted.

The cpu_is_u5500() macros that can read out the CPU ID is left
until the next kernel cycle, this makes it possible to merge
deletion of dependent drivers without breakage.

This also has the upside of removing the mailbox driver which was
our only driver that was outside the drivers/* hiearchy, now the
machine directory only handles machines and nothing else.

is an application processor without internal modem. This is the
most basic part with ASIC ID, CPU-related fixes, IRQ list, register
ranges, timer, UART, and L2 cache setup. This is based on a patch
by Michel Jaouen which was rewritten to fit with the latest 3.3
kernel.

The default configuration for a number of I2C and keypad pins was
to pull-up. However on most reference designs the electronics
already contain external pull-ups which means the internal
pull-ups will lower the common resistance and increase power
consumption on these lines, and in some reference designs the
keypad inputs are not used so this will just cause problems. So
remove these pull-ups and add them on demand instead if needed.

This will not do much by itself because the device from the

are converted as well. The next step is to move over one
