The IFC6560 is a board from Inforce Computing, built around the SDA660
SoC. This patch describes core clocks, some regulators from the two
PMICs, debug uart, storage, bluetooth and audio DSP remoteproc.
The regulator settings are inherited from prior work by Konrad Dybcio
and AngeloGioacchino Del Regno.
