This acpi driver provide supports for freefall sensors SMO8800/SMO8810 which
can be found on Dell Latitude laptops. Driver register /dev/freefall misc
device which has same interface as driver hp_accel freefall driver. So any
existing applications for HP freefall sensor /dev/freefall will work for with
this new driver for Dell Latitude laptops too.

Let the xo15-ebook driver depend on OLPC as all other OLPC drivers
already do. Add COMPILE_TEST as an alternative for both xo1-rfkill
and xo15-ebook, to increase the build testing coverage.

This reverts commit 997ab407d2b4e7d7ce2788d2de68435eb94fcfec. This driver is
replaced by the more general SOC IOSF driver in commit 46184415368a.

ACPI_VIDEO no longer depends on VIDEO_OUTPUT_CONTROL, so drivers which
want to select ACPI_VIDEO no longer have to select
VIDEO_OUTPUT_CONTROL.

Current Intel SOC cores use a MailBox Interface (MBI) to provide access to unit
devices connected to the system fabric. This driver implements access to this
interface on BayTrail platforms. This is a requirement for drivers that need
access to unit registers on the platform (e.g. accessing the PUNIT for power
management features such as RAPL). Serialized access is handled by all exported
routines with spinlocks.

The API includes 3 functions for access to unit registers:

int bt_mbi_read(u8 port, u8 opcode, u32 offset, u32 *mdr)
int bt_mbi_write(u8 port, u8 opcode, u32 offset, u32 mdr)
int bt_mbi_modify(u8 port, u8 opcode, u32 offset, u32 mdr, u32 mask)

port:	indicating the unit being accessed
opcode:	the read or write port specific opcode
offset:	the register offset within the port
mdr:	the register data to be read, written, or modified
mask:	bit locations in mdr to change

Returns nonzero on error

Note: GPU code handles access to the GFX unit. Therefore access to that unit
with this driver is disallowed to avoid conflicts.

It makes sense to split out the Chromebook/Chromebox hardware platform
drivers to a separate subdirectory, since some of it will be shared
between ARM and x86.

This moves over the existing chromeos_laptop driver without making
any other changes, and adds appropriate Kconfig entries for the new
directory. It also adds a MAINTAINERS entry for the new subdir.
