From: Pali Rohár <pali@kernel.org>

[ Upstream commit 67bbb62f61e810734da0a1577a9802ddaed24140 ]

Channel 0 of SA56004ED chip refers to internal SA56004ED chip sensor (chip
itself is located on the board) and channel 1 of SA56004ED chip refers to
external sensor which is connected to temperature diode of the P2020 CPU.
