Linus Torvalds c67d9ce166 ARM: SoC board support updates for 3.16 
The bulk of this branch is updates for Renesas Shmobile. They are still
 doing some enablement for classic boards first, and then come up with DT
 bindings when they've had a chance to learn more about the hardware. Not
 necessarily a bad way to go about it, and they're looking at moving some
 of the temporary board code resulting from it to drivers/staging instead
 to avoid the churn here.
 
 As a result of the shmobile clock cleanups, we end up merging quite a
 bit of SH code here as well. We ended up merging it here instead of in
 the cleanup branch due to the other board changes depending on it.

/*
* Ether LEDs on the Koelsch board are named LINK and ACTIVE which corresponds
* to non-default 01 setting of the Micrel KSZ8041 PHY control register 1 bits
* 14-15. We have to set them back to 01 from the default 00 value each time
* the PHY is reset. It's also important because the PHY's LED0 signal is
* connected to SoC's ETH_LINK signal and in the PHY's default mode it will
* bounce on and off after each packet, which we apparently want to avoid.
