Subject: powerpc: dts: turris1x.dts: Add channel labels for temperature sensor
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=67bbb62f61e810734da0a1577a9802ddaed24140;p=linux.git

powerpc: dts: turris1x.dts: Add channel labels for temperature sensor

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.
