This patch adds macros for register writing/reading. This is needed for
adding support Exynos5433 MIPI DSI driver, not by using if statement, but
by using driver data.

This patch renames pll_clk to sclk_clk. The clock referenced by pll_clk
is actually not the pll input clock for dsi. The pll input clock comes
from the board's oscillator directly. But for the backward
compatibility, the old clock name "pll_clk" is also OK.

MIC(Mobile image compressor) is newly added IP in Exynos5433. MIC
resides between decon and mipi dsim, and compresses frame data by 50%.
With dsi, not display port, to send frame data to the panel, the
bandwidth is not enough. That is why this compressor is introduced.

When there are multiple ports or multiple endpoints in a port, they have to be
distinguished by the value of reg property. It is common. The drivers can get
the specific endpoint in the specific port via this function. Now the drivers
have to implement this code in themselves or have to force the order of dt nodes
to get the right node.

ASoC: Further updates for v4.2
There's a bunch of additional updates and fixes that came in since my
orignal pull request here, including DT support for rt5645 and fairly
large serieses of cleanups and improvements to tas2552 and rcar.

ASoC: Updates for v4.2
The big thing this release has been Liam's addition of topology support
to the core. We've also seen quite a bit of driver work and the
continuation of Lars' refactoring for component support.
- Support for loading ASoC topology maps from firmware, intended to be
used to allow self-describing DSP firmware images to be built which
can map controls added by the DSP to userspace without the kernel
needing to know about individual DSP firmwares.
- Lots of refactoring to avoid direct access to snd_soc_codec where
it's not needed supporting future refactoring.
- Big refactoring and cleanup serieses for the Wolfson ADSP and TI
TAS2552 drivers.
- Support for TI TAS571x power amplifiers.
- Support for Qualcomm APQ8016 and ZTE ZX296702 SoCs.
- Support for x86 systems with RT5650 and Qualcomm Storm.

As the AEAD conversion is still ongoing, we do not yet wish to
export legacy AEAD implementations to user-space, as their calling
convention will change.
This patch actually disables all AEAD algorithms because some of
them (e.g., cryptd) will need to be modified to propagate this flag.
Subsequent patches will reenable them on an individual basis.

The bit CRYPTO_ALG_INTERNAL was added to stop af_alg from accessing
internal algorithms. However, af_alg itself was never modified to
actually stop that bit from being used by the user. Therefore the
user could always override it by specifying the relevant bit in the
type and/or mask.
This patch silently discards the bit in both type and mask.

The RNG may not be available during early boot, e.g., the relevant
modules may not be included in the initramfs. As the RNG Is only
needed for IPsec, we should not let this prevent use of ciphers
without IV generators, e.g., for disk encryption.
This patch postpones the RNG allocation to the init function so
that one failure during early boot does not make the RNG unavailable
for all subsequent users of the same cipher.
More importantly, it lets the cipher live even if RNG allocation
fails. Of course we no longer offer IV generation and which will
fail with an error if invoked. But all other cipher capabilities
will function as usual.

This patch adds a new crypto_user command that allows the admin to
