Bug ID: 176371
Summary: 80860F14:01 SDIO Controller not probed by ACPI_LPSS
Product: ACPI
Version: 2.5
Kernel Version: 4.8.0
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: Config-Other

DSDT decompiled
CPU: Intel Atom x5-z8300 (CherryTrail)
The issue at hand is a SDIO Controller (80860F14:01) is not being probed by
drivers/acpi/acpi_lpss.c despite having its acpi_id in the list. The said
device is enumerated in acpi_namespace and report 'status'=15 and
'power_state'=D0.
As a consequence of this event, a platform_device isn't created for the
acpi_device and so the platform_driver sdhci-acpi can't probe it. This issue
persists across BayTrail and CherryTrail SOCs.
