These are intended to be picked up by the stable branches. To circumvent further mistakes, I new device tree constants for the qoriq binding. This should make it far easier for humans to read the clockgen nodes. The 4th patch convert the LS1028A device tree include to use the new constants. The last five patches add a clock driver for the FlexSPI controller on layerscape SoCs. There is a single register which can control the divider value. Right now the LS1028A and the LX2160A aren't able to switch the SCK frequency on the FlexSPI interface. I've included the first four patches in this series, otherwise there would be merge conflicts, because they depend on the new qoriq device tree constants.
