Odroid HC1 board has built-in JMicron USB to SATA bridge, which supports
UAS protocol. Compile-in support for it (instead of enabling it as module)
to make sure that all built-in storage devices are available for rootfs.
The bridge itself also supports fallback to standard USB Mass Storage
protocol, but USB Mass Storage class doesn't bind to it when UAS is
compiled as module and modules are not (yet) available.

exynos_defconfig, beside serving as a reference config for Exynos-based
devices, is used by developers during regular development work.
Enabling options responsible for locking tests allows to discover bugs
in drivers and mach code earlier.
This enables:
1. Detection of sleeping in atomic sections (DEBUG_ATOMIC_SLEEP),
2. Full lockdep (DEBUG_LOCK_ALLOC and PROVE_LOCKING which makes other
lock debug entries unneeded),
3. Detection of soft, kernel lockups (SOFTLOCKUP_DETECTOR).

Current CMA size of 64 Mbytes is right on the edge of being small when
several drivers need to allocate large CMA buffers.
For example, if the s5p-mfc driver needs to pre-allocate CMA memory to
decode a H.264 1080p video, then there won't be enough CMA memory left
for other drivers, such as the exynos-drm driver that may need to
allocate GEM buffers for the display manager.
Increasing CMA size to 96 Mbytes in exynos_defconfig addresses use-cases
such as these.

NFS client is already enabled (NFS_FS) and by default it enables clients
for version 2 and 3. Enable explicitly the version 4 client to utilize
the newer protocol.
The NFS client is especially useful for testing kernel in automated

Defconfig updates are kept separate from other branches mostly to avoid
conflicts between the different categories (driver branch enabling something
that has context conflict with SoC options, etc).
A lot of this again is scattered across the various hardware platforms.
multi_v7_defconfig, our "generic" config for most 32-bit platforms has
been gone through by Marvell Berlin maintainers and added most options
they need to run on their hardware. Broadcom NSP is also added there,
and the new Atmel SAMA5D2 (added last release). Rockchip also has display
and other devices supported in that config.
In addition to that, the usual small churn of new options being added
here and there.

Mixer driver is selected by CONFIG_DRM_EXYNOS_HDMI option. Since Exynos5433
HDMI does not require Mixer. There will be separate options to select Mixer
and HDMI. Adding new option to defconfig before Kconfig will allow to keep
bisectability.

The Marvell WiFi-Ex driver tries to load a firmware on probe. So if the
driver is built-in and probed before a firmware is available, this is
not loaded and the chip does not work.
This happens for example if an initramfs isn't used since the driver is
probed before the root filesystem is mounted.
Change the default config since the driver isn't needed for machines to
boot and is more convenient to have it enabled as a module to avoid
requiring an initramfs or to have the firmware built into the kernel.

The simplefb driver allows the kernel to render on a pre-allocated
buffer that's been initialized by firmware before the kernel boots.
This option was enabled to have display working on the Exynos5250
Snow Chromebook by commit da9d0fbf5e ("ARM: exynos: defconfig
update") since proper DRM/KMS support did not exist at that time.
But now that the Exynos DRM driver has support for this hardware,
there is no need to have simplefb enabled. In fact, if a user has
a u-boot that injects the simplefb dev node to the FDT before pass
it to the kernel, display won't be properly initialized and only a
blank screen will be shown since there isn't a proper handoff from
the simplefb driver to the Exynos DRM driver.

This is a collection of a few late fixes and other misc. stuff that
had dependencies on things being merged from other trees.
The bulk of the changes are for samsung/exynos SoCs for some changes
that needed a few minor reworks so ended up a bit late. The others
are mainly for qcom SoCs: a couple fixes and some DTS updates.
There's one conflict with drivers/cpufreq/exynos-cpufreq.c because
it's now been completely removed, but there were some fixes that hit
mainline in the meantime.
