2020-07-28acpi: Fix dptf_write_fan_perf to include Revision fieldTim Wawrzynczak
When emitting a fan's _FPS (Fan Performance States) table, the revision field was missing. According to ACPI spec 6.3, the current revision is zero, so add that Package entry before the others.

2020-07-18dptf: Fix scope of TCPU deviceTim Wawrzynczak
In the initial DPTF refactor, the scope of the TCPU device was incorrectly set as \_SB, instead of \_SB.PCI0. However, because of the way that the acpi_inject_dsdt() callback currently works (it injects contents before the dsdt.aml file), the Scope where the TCPU device lives (\_SB.PCI0) doesn't exist yet. Therefore, to avoid playing games with *when* things are defined in the DSDT, switch to defining all of the DPTF devices in the SSDT.

2020-07-07dptf: Add support for IDSPTim Wawrzynczak
\_SB.DPTF.IDSP adverties to the DPTF daemon which policies the implementation supports. Added a new acpigen function to figure out which policies are used, and fills out IDSP appropriately.

2020-07-07dptf: Add support for Fan and TSR optionsTim Wawrzynczak
DPTF has several options on how to control the fan (fine-grained speed control, minimum speed change in percentage points, and whether or not the DPTF device should notify the Fan if it detects low speed). Individual TSRs can also set GTSH, which is the amount of hysteresis inherent in the measurement, either from circuitry (if analog), or in firmware (if digital).

2020-07-07dptf: Add support for Running Average Power LimitsTim Wawrzynczak
This change adds support for emitting the PPCC table, which describes the ranges available as knobs for DPTF to tune. It can support min/max power, min/max time window for averaging, and the minimum adjustment size (granularity or step size) of each power limit. The current implementation only supports PL1 and PL2.

2020-07-07dptf: Add support for Fan Performance StatesTim Wawrzynczak
This change adds support for generating the _FPS table for the DPTF Fan object. The table describes different levels of fan activity that may be applied to the system in order to actively cool it. The information includes fan speed at a (rough) percentage level, fan speed in RPM, potential noise level in centibels, and power in mA.

2020-07-07dptf: Add support for Charger Performance StatesTim Wawrzynczak
This change generates the DPTF TCHG.PPSS table in the SSDT. This table describes different charging rates which are available to use. DPTF can pick different rates in order to passively cool (or not) the system.

2020-07-07dptf: Add support for Critical PoliciesTim Wawrzynczak
This patch adds support for DPTF Critical Policies, which are consist of Method definitions only. They are `_CRT` and `_HOT`, which are defined as temperature thresholds that, when exceeded, will execute a graceful suspend or a graceful shutdown, respectively.
