Hello build bot (Jenkins), Furquan Shaikh, Tim Wawrzynczak,

I'd like you to reexamine a change. Please visit

to look at the new patch set (#4).

Change subject: drivers/acpi: Add device tree driver to generate thermal zone

drivers/acpi: Add device tree driver to generate thermal zone

Given the following device tree entry:
    chip drivers/acpi/thermal_zone
        register "description" = ""SOC""

use chrome_ec as temperature_controller

register "sensor_id" = "0"

register "polling_period" = "10"

register "critical_temperature" = "91"

register "passive_config" = "{
            .temperature = 85,
        }"

device generic 0 on end
    end

It will generate the following:
    Scope (_TZ)
    {
        ThermalZone (TM00)
        {
            Name (_STR, "CPU")  // _STR: Description String
            Name (_RTV, Zero)  // _RTV: Relative Temperature Values
            Name (_TZP, 0x64)  // _TZP: Thermal Zone Polling
            Name (_CRT, 0x0E39)  // _CRT: Critical Temperature
            Name (_PSV, 0x0DFD)  // _PSV: Passive Temperature
            Name (_PSL, Package (0x10)  // _PSL: Passive List
            {
                _SB.CP00,
                _SB.CP01,
                _SB.CP02,
                _SB.CP03,
                _SB.CP04,
                _SB.CP05,
                _SB.CP06,
                _SB.CP07,
                _SB.CP08,
                _SB.CP09,
            })
            Name (_TC1, 0x02)  // _TC1: Thermal Constant 1
            Name (_TC2, 0x05)  // _TC2: Thermal Constant 2
            Name (_TSP, 0x14)  // _TSP: Thermal Sampling Period
            Method (_TMP, 0, Serialized)  // _TMP: Temperature
            {
                Return (_SB.PCI0.LPCB.EC0.TSRD (Zero))
            }
        }
    }
