TPS65132 is a dual output regulator chip. It is usually used for
providing positive and negative supply voltages for LCD panel source
driver ICs.
The chip has a positive supply rail and a negative supply rail. Both
rails support 4V~6V output voltage range and each rail can be
controlled separately.

The memory accelerator (MEM ACC) controls the delays applied during
memory access. These delays vary based on the power-mode (corner)
on which the memory is connected. This driver adds a regulator
interface to configure the power-mode of the memory accelerator

This change removes source files from the kernel tree that
were not being used during make. The list of used files
was generated using an annotated make log and was then
compared with new files added since the public release of
kernel version 3.10.00. New files which were added but
not used have been removed from the tree.
A diff was also run to determine the list of files that had
been modified since the release of kernel version 3.10.00.
These files were then scrubbed based on the current kernel
configuration, removing invalid and unused conditionals.
Some files which support planned functionality or are
useful in debugging have been excluded from this reap.

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac9651: "EHCI:
