But this IRQ 86 is described in the _CRS control method of INT3401 device, thus we should enumerate INT3401 to set the IRQ descriptor when Intel SoC DTS thermal driver is built.

Intel SoC DTS thermal driver on Baytrail platform uses IRQ 86 for
critical overheating notification.
But this IRQ 86 is described in the _CRS control method of INT3401 device,
thus we should enumerate INT3401 to set the IRQ descriptor when
Intel SoC DTS thermal driver is built.

ACPI/int340x_thermal: enumerate INT340X devices even if they're not in _ART/_TRT 2015-01-06T00:17:06+00:00 Zhang Rui rui.zhang@intel.com 2015-01-04T06:24:23+00:00 48628e4015dbd77b676c5a9b5bd145a284f8bb93 For some INT340X thermal devices, even if they are not referred in _TRT/_ART table, they still can be used by userspace for thermal control. Thus change the code to enumerated all the INT340X devices, no matter if they're referred in _TRT/_ART or not.

ACPI: introduce ACPI int340x thermal scan handler 2014-09-11T15:35:15+00:00 Zhang Rui rui.zhang@intel.com 2014-03-13T16:34:05+00:00 3230bbfce8a9270acc77fafd0d9ff90e94f28993 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.
