The clocks on dm816x are a bit different from the other omap
variants. The clocks are sourced from a FAPLL (Flying Adder PLL)
unlike on other omaps. Other than that, it's a similar setup
to am33xx with extra muxes and dividers that can be defined
as existing component clocks.

Merge branch 'link_netns'
Nicolas Dichtel says:
====================
netns: allow to identify peer netns
The goal of this serie is to be able to multicast netlink messages with an
attribute that identify a peer netns.
This is needed by the userland to interpret some information contained in
netlink messages (like IFLA_LINK value, but also some other attributes in case
of x-netns netdevice (see also
http://thread.gmane.org/gmane.linux.network/315933/focus=316064 and
http://thread.gmane.org/gmane.linux.kernel.containers/28301/focus=4239)).
Ids of peer netns can be set by userland via a new rtnl cmd RTM_NEWNSID. When
the kernel needs an id for a peer (for example when advertising a new x-netns
interface via netlink), if the user didn't allocate an id, one will be
automatically allocated.
These ids are stored per netns and are local (ie only valid in the netns where
they are set). To avoid allocating an int for each peer netns, I use
idr_for_each() to retrieve the id of a peer netns. Note that it will be possible
to add a table (struct net -> id) later to optimize this lookup if needed.
Patch 1/4 introduces the rtnetlink API mechanism to set and get these ids.
Patch 2/4 and 3/4 implements an example of how to use these ids when advertising
information about a x-netns interface.
And patch 4/4 shows that the netlink messages can be symetric between a GET and
a SET.
iproute2 patches are available, I can send them on demand.
Here is a small screenshot to show how it can be used by userland.
$ ip netns add foo
$ ip netns del foo
$ ip netns

add vxlan in patch #3
RFCv3 -> v4:

add copyright text in the new netns.h file
RFCv2 -> RFCv3:
ids are now defined by userland (via netlink). Ids are stored in each netns
(and they are local to this netns).
add get_link_net support for ip6 tunnels
netnsid is now a s32 instead of a u32
RFCv1 -> RFCv2:
remove useless ()
ids are now stored in the user ns. It's possible to get an id for a peer netns
only if the current netns and the peer netns have the same user ns parent.

With this patch, a user can define an id for a peer netns by providing a FD or a
PID. These ids are local to the netns where it is added (ie valid only into this
netns).
The main function (ie the one exported to other module), peernet2id(), allows to
get the id of a peer netns. If no id has been assigned by the user, this
function allocates one.
These ids will be used in netlink messages to point to a peer netns, for example
in case of a x-netns interface.

It is possible for ata_sff_flush_pio_task() to set ap->hsm_task_state to
HSM_ST_IDLE in between the time __ata_sff_port_intr() checks for HSM_ST_IDLE
and before it calls ata_sff_hsm_move() causing ata_sff_hsm_move() to BUG().
This problem is hard to reproduce making this patch hard to verify, but this
fix will prevent the race.
I have not been able to reproduce the problem, but here is a crash dump from
a 2.6.32 kernel.
On examining the ata port's state, its hsm_task_state field has a value of HSM_ST_IDLE:
crash> struct ata_port.hsm_task_state ffff881c1121c000
hsm_task_state = 0
Normally, this should not be possible as ata_sff_hsm_move() was called from ata_sff_host_intr(),
which checks hsm_task_state and won't call ata_sff_hsm_move() if it has a HSM_ST_IDLE value.

This function will set ap->hsm_task_state to HSM_ST_IDLE, and has no locking around setting this

HSM_ST_IDLE at a fatal moment, which will trigger a kernel BUG.

Currently, we provide the iommu_ops.iova_to_phys service by doing a
table walk in software to translate IO virtual addresses to physical
addresses. On SMMUs that support it, it can be useful to ask the SMMU
itself to do the translation. This can be used to warm the TLBs for an
SMMU. It can also be useful for testing and hardware validation.
Since the address translation registers are optional on SMMUv2, only
enable hardware translations when using SMMUv1 or when SMMU_IDR0.S1TS=1
and SMMU_IDR0.ATOSNS=0, as described in the ARM SMMU v1-v2 spec.

Files created with __shmem_file_stup() appear to have somewhat fake
dentries which make them look like root directories and not get
the label the current process or ("*") star meant for tmpfs files.

When an error occurs during an scm call the error returned is remapped so
we lose the original error code. This means that when an error occurs we
have no idea what actually failed within the secure environment.
Add a logging statement that will log the actual error code from scm call
allowing us to easily determine what caused the error to occur.

scm_call flushes the entire cache before calling into the secure world.
This is both a performance penalty as well as insufficient on SMP systems
where the CPUs possess a write-back L1 cache. Flush only the command and
response buffers instead, moving the responsibility of flushing any other
cached buffer (being passed to the secure world) to callers.

Instead of hardcoding the cacheline size as 32, get the cacheline size from
the CTR register.

The cache invalidation in scm_call() correctly rounds down the start
address to invalidate the beginning of the cacheline but doesn't properly
round up the 'end' address to make it aligned. The last chunk of the
buffer won't be invalidated when 'end' is not cacheline size aligned so
make sure to invalidate the last few bytes in such situations. It also
doesn't do anything about outer caches so make sure to invalidate and flush
those as well.

We have this on at least 3517-evm and dm8168-evm. Let's
enable davinci_emac so those can be booted with NFSroot.

This reverts commit ba1debdfed.
Oliver reported that it breaks network-manager, for some reason with
this patch NM decides that the device isn't wireless but "generic"
(ethernet), sees no carrier (as expected with wifi) and fails to do
anything else with it.
Revert this to unbreak userspace.

CP microcode uses undocumented bits in this register to record queue
state information. The KFD zeroes these bits in update_mqd, when invoked
through the UPDATE_QUEUE ioctl, causing incoherent state when the ioctl
is used to successively unmap and map a queue.
Since the queue type cannot be changed in this path, move the MQD write
to init_mqd.

dqm->queue_count tracks queues in the active state only. In a few
places this count is modified unconditionally, leading to an incorrect
value when the UPDATE_QUEUE ioctl is used to make a queue inactive.

In principle if this function was called with "value" == NULL and "len"
not NULL it could return different results for the "len" compared to a
case where "name" was not NULL. This is a hypothetical case that does
not exist in the kernel, but it's a logic bug nonetheless.
