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.
