I applied the three clk ones to an immutable branch named
'clk-st-critical' in the clk tree and merged this into clk-next.
I'm not comfortable taking the spi patch as I suspect that will
break something unless the dts patches are applied.

Please use this branch to base your dts and spi patches on so it
can be merged through arm-soc without introducing some bisection
hole.
