From 3230bbfce8a9270acc77fafd0d9ff90e94f28993 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Fri, 14 Mar 2014 00:34:05 +0800 Subject: ACPI: introduce ACPI int340x thermal scan handler Newer laptops and tablets that use ACPI may have thermal sensors and other devices with thermal control capabilities outside the core CPU/SOC, for thermal safety reasons. They are exposed for the OS to use via 1) INT3400 ACPI device object as the master. 2) INT3401 ~ INT340B ACPI device objects as the slaves. This patch introduces a scan handler to enumerate the INT3400 ACPI device object to platform bus, and prevent its slaves from being enumerated before the controller driver being probed.
