Rashika Kheria 475879d651 drivers: platform: Include appropriate header file in mxm-wmi.c
This patch includes appropriate header file linux/mxm-wmi.h in
x86/mxm-wmi.c because functions mxm_wmi_call_mxds(), mxm_wmi_call_mxmx()
and mxm_wmi_supported() have their prototype declaration in
linux/mxm-wmi.h.

Thus, it also eliminates the following warnings in x86/mxm-wmi.c:
drivers/platform/x86/mxm-wmi.c:43:5: warning: no previous prototype for ‘mxm_wmi_call_mxds’ [-Wmissing-prototypes]
drivers/platform/x86/mxm-wmi.c:68:5: warning: no previous prototype for ‘mxm_wmi_call_mxmx’ [-Wmissing-prototypes]
drivers/platform/x86/mxm-wmi.c:93:6: warning: no previous prototype for ‘mxm_wmi_supported’ [-Wmissing-prototypes]

Lv Zheng 8b48463f89 ACPI: Clean up inclusions of ACPI header files
Replace direct inclusions of <acpi/acpi.h>, <acpi/acpi_bus.h> and
<acpi/acpi_drivers.h>, which are incorrect, with <linux/acpi.h>
inclusions and remove some inclusions of those files that aren't
necessary.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h>
should not be included directly from any files that are built for
CONFIG_ACPI unset, because that generally leads to build warnings about
undefined symbols in !CONFIG_ACPI builds.  For CONFIG_ACPI set,
<linux/acpi.h> includes those files and for CONFIG_ACPI unset it
provides stub ACPI symbols to be used in that case.

Second, there are ordering dependencies between those files that always
have to be met.  Namely, it is required that <acpi/acpi_bus.h> be included
prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the
latter depends on are always there.  And <acpi/acpi.h> which provides
basic ACPICA type declarations should always be included prior to any other
ACPI headers in CONFIG_ACPI builds.  That also is taken care of including
<linux/acpi.h> as appropriate.

Dave Airlie 000703f44c mxm/wmi: add MXMX interface entry point.
The MXMX method appears to be a mutex of some sort.

Dave Airlie 99b38b4acc platform/x86: add MXM WMI driver.
MXM is a laptop graphics card form-factor + interface specification,
this adds an initial stub driver to talk to the MXM WMI interface.

The only method used is the MUX switching method needed to do switchable
graphics on the nvidia chipsets.
