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.

Fixes: 54c15ec3b738 ("powerpc: dts: Add DTS file for CZ.NIC Turris 1.x routers")

With this change userspace 'sensors' applications prints labels:

    $ sensors
    sa56004-i2c-0-4c
    Adapter: MPC adapter (i2c@3000)
    board:        +34.2°C  (low  =  +0.0°C, high = +70.0°C)
                           (crit = +85.0°C, hyst = +75.0°C)
    cpu:          +58.9°C  (low  =  +0.0°C, high = +70.0°C)
                           (crit = +85.0°C, hyst = +75.0°C)

And without this change it prints just generic tempX names:

    $ sensors
    sa56004-i2c-0-4c
    Adapter: MPC adapter (i2c@3000)
    temp1:        +43.0°C  (low  =  +0.0°C, high = +70.0°C)
                           (crit = +85.0°C, hyst = +75.0°C)
    temp2:        +63.4°C  (low  =  +0.0°C, high = +70.0°C)
                           (crit = +85.0°C, hyst = +75.0°C)

I'm not sure if you want UPPERCASE, lowercase, PascalCase, kebab-case
or snake_case format of labels. Or if you want also "temp" or
"temperature" keyword in the label. So please adjust label to the
preferred one, if proposed format is not the correct.

Ok, if nobody complains then please take this patch as is.

Yep.

With these dts patches it always helps if you tell me that it passes the
DT schema checks, so that I don't get yelled at by the DT people :)

Mostly dt schemas for p1/p2 are incomplete, I sent more patches but they
are waiting and I was not able to setup & run dt schema checker. Hence
I tested everything on the hardware to ensure that it works correctly.
And this patch works on Turris 1.1 board, I also tested sensors tool.
So the important is what is in DTS file, the stuff which is used on HW.

Applied to powerpc/next.
