This patch series adds a phase offset feature to the SI5351 clock
outputs. This is necessary to generate differential clocks or
arbitrary phase shifts with respect to other clock outputs.

Patch 1 adds the DT documentation to configure the phase offset.

Patch 2 implements the phase offset feature by adding *_set_phase()
functions to the multisynth and clockout stages.

Tested on a Xilinx Zynq (ARM Cortex-A9) board with Si5351A-B-GT for
several frequencies and phase offsets.

  clk: si5351: Add DT property for phase offset
  clk: si5351: Add clock output phase offset
