Merge tag 'drivers2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: More SoC driver updates" from Olof Johansson:
 "This branch contains a handful of driver updates, mostly to the
  LPC32xx platform but also for Samsung EXYNOS and Davinci.

  It had a few context conflicts against patches already merged through
  fixes-non-critical.  We should have resolved this early during the
  development cycle by pulling them in as a dependency, instead I did it
  after the fact this time."

help
Say Y here to use the LPC internal fast IRAM (i.e. 256KB SRAM) as
network buffer. If the total combined required buffer sizes is
larger than the size of IRAM, then SDRAM will be used instead.
This can be enabled safely if the IRAM is not intended for other
uses.

bool "Check to enable MII support or leave disabled for RMII support"
help
Say Y here to enable MII support, or N for RMII support. Regardless of
which support is selected, the ethernet interface driver needs to be
selected in the device driver networking section.
The PHY3250 reference board uses RMII, so users of this board should
say N.
