From 6256ebd5daf93505f12b66916fb1b961b38f4cf2 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Sun, 17 Jul 2016 13:45:32 -0700 Subject: ACPI / DPTF: Add DPTF power participant driver This driver adds support for Dynamic Platform and Thermal Framework (DPTF) Platform Power Participant device (INT3407) support. This participant is responsible for exposing platform telemetry such as: max_platform_power platform_power_source adapter_rating battery_steady_power charger_type These attributes are presented via sysfs interface under the INT3407 platform device: $ls /sys/bus/platform/devices/INT3407\:00/dptf_power/ adapter_rating_mw battery_steady_power_mw charger_type max_platform_power_mw platform_power_source ` ACPI methods description used in this driver: PMAX: Maximum platform power that can be supported by the battery in mW. PSRC: System charge source, 0x00 = DC 0x01 = AC 0x02 = USB 0x03 = Wireless Charger ARTG: Adapter rating in mW (Maximum Adapter power) Must be 0 if no AC adapter is plugged in. CTYP: Charger Type, Traditional : 0x01 Hybrid: 0x02 NVDC: 0x03 PBSS: Returns max sustained power for battery in milliWatts. The INT3407 also contains _BTS and _BIX objects, which are compliant to ACPI 5.0, specification. Those objects are already used by ACPI battery (PNP0C0A) driver and information about them is exported via Linux power supply class registration.
