[v3,0/9] clk: qoriq fixes and new fsl-flexspi driver

Message

Michael Walle Nov. 8, 2020, 6:51 p.m. UTC

The first two patches fix clock references for the ENETC and the
FlexSPI on the LS1028A. 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.
