Commit Message

Bjorn Andersson Aug. 24, 2021, 3:10 p.m. UTC 
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.

Maybe call it 2p95 (and not 29p5) like the one above, for consistency?

Maybe call it 2p95 too?
