In UIC error interrupt handling, it checks if UIC data link layer error
code indicates PA_INIT_ERROR in order to determine whether a fatal error
handling is needed or not.
But the code tries to read UIC data link layer error code from wrong
REG_UIC_ERROR_CODE_PHY_ADAPTER_LAYER, it should be
REG_UIC_ERROR_CODE_DATA_LINK_LAYER.

Link start-up requires long time with multiphase handshakes
between UFS host and device. This affects driver's probe time.
This patch let link start-up run asynchronously. Link start-up
will be executed at the end of prove separately.
Along with this change, the following is worked.
Defined completion time of uic command to avoid a permanent wait.
Added mutex to guarantee of uic command at a time.
Adapted some sequence of controller initialization after link statup
according to HCI standard.

nfs4_init_session was originally written to be called prior to
nfs4_init_channel_attrs, setting the session target_max response and request
sizes that nfs4_init_channel_attrs would pay attention to.
In the current code flow, nfs4_init_session, just like nfs4_init_ds_session
for the data server case, is called after the session is all negotiated, and
is actually used in a RECLAIM COMPLETE call to the server.
Remove the un-needed fc_target_max response and request fields from
nfs4_session and just set the max_resp_sz and max_rqst_sz in
nfs4_init_channel_attrs.

The current scheme is to try and pick the auth flavor that the server
prefers. In some cases though, we may find that we're not actually
able to use that auth flavor later. For instance, the server may
prefer an AUTH_GSS flavor, but we may not be able to get GSSAPI creds.
The current code just gives up at that point. Change it instead to
try the ->create_server call using each of the different authflavors
in the server's list if one was not specified at mount time. Once
we have a successful ->create_server call, return the result. Only
give up and return error if all attempts fail.

In case a device has three tags available we still reserve two of them
for sync IO. That leaves only a single tag for async IO such as
writeback from flusher thread which results in poor performance.
Allow async IO to consume two tags in case queue has three tag availabe
to get a decent async write performance.
This patch improves streaming write performance on a machine with such disk
from ~21 MB/s to ~52 MB/s. Also postmark throughput in presence of
streaming writer improves from 8 to 12 transactions per second so sync
IO doesn't seem to be harmed in presence of heavy async writer.

This patch changes the firmware file names of the FIMC-IS subsystem.
It is needed since there are different firmwares used across various
SoC series, e.g. Exynos4 and Exynos5.
Also the sensor specific "setfile" name is changed, to account for
it depends on an image sensor and is also specific to the FIMC-IS
and the SoC.
This is a change for a driver merged in 3.10.

Add compatible property for the Exynos5250 and enable the frame start
and frame end interrupts. These interrupts are needed for the Exynos5
FIMC-IS firmware. The driver enables those interrupt only where available,
depending on the 'compatible' property. This can be optimized further,
by exposing some API at the subdev driver, so the host driver can enable
extra interrupts only for the image processing chains involving FIMC-IS.

This patch adds support for the Exynos5250 SoC variant of the FIMC-LITE
IP. A 'compatible' string is added for Exynos5250 compatible devices
and the capture DMA handling is reworked to use the FLITE_REG_CIFCNTSEQ
register, masking output DMA buffer address slots. The frame interrupt
is enabled so there are now 2 interrupts per frame. This likely can be
optimized in future by using any status registers that allow to figure
out what the last and the currently written frame buffer is. It would
also be more reliable in cases where there are high interrupt service
latencies.
