Linus Torvalds f9efbce633 ARM: SoC DT updates for 3.13
Most of this branch consists of updates, additions and general churn of
 the device tree source files in the kernel (arch/arm/boot/dts). Besides
 that, there are a few things to point out:
 
 - Lots of platform conversion on OMAP2+, with removal of old board files
   for various platforms.
 - Final conversion of a bunch of ux500 (ST-Ericsson) platforms as well
 - Some updates to pinctrl and other subsystems. Most of these are for
   DT-enablement of the various platforms and acks have been collected.

NOTE: During automatic conversion of these files to use the pinconfig

According to the comment the function for pad SSP2_SS0 should have
been MX28_PAD_SSP2_SS0__GPIO_2_19, while the given value 0x2131
represents: MX28_PAD_SSP2_SS0__AUART3_TX

I used the later (though probably wrong) definition because that's
what is actually being used in the DTB.

Shawn Guo 53f9443da6 clk: mxs: replace imx23 clk_register_clkdev with clock DT lookup
It really becomes a maintenance issue that every time a device needs
to look up (clk_get) a clock we have to patch kernel clock file to call
clk_register_clkdev for that clock.

Since clock DT support which is meant to resolve clock lookup in device
tree is in place, the patch moves imx23 client devices' clock lookup
over to device tree, so that any new lookup to be added at later time
can just get done in DT instead of kernel.
