This driver was only enabling the first clock on the device, regardless
of its name. However, this controller logic can have multiple clocks
which should all be enabled. Add support for enabling additional clocks.
The clock names used are matching those used in the Xilinx version of this
driver as well as the Xilinx device tree generator, except for mgt_clk
which is not present there.
For backward compatibility, if no named clocks are present, the first
clock present is used for determining the MDIO bus clock divider.

mld: change context from atomic to sleepable
This patchset changes the context of MLD module.
Before this patchset, MLD functions are atomic context so it couldn't use
sleepable functions and flags.
There are several reasons why MLD functions are under atomic context.
1. It uses timer API.
Timer expiration functions are executed in the atomic context.
2. atomic locks
MLD functions use rwlock and spinlock to protect their own resources.
So, in order to switch context, this patchset converts resources to use
RCU and removes atomic locks and timer API.
1. The first patch convert from the timer API to delayed work.
Timer API is used for delaying some works.
MLD protocol has a delay mechanism, which is used for replying to a query.
If a listener receives a query from a router, it should send a response
after some delay. But because of timer expire function is executed in
the atomic context, this patch convert from timer API to the delayed work.
2. The fourth patch deletes inet6_dev->mc_lock.
The mc_lock has protected inet6_dev->mc_tomb pointer.
But this pointer is already protected by RTNL and it isn't be used by
datapath. So, it isn't be needed and because of this, many atomic context
critical sections are deleted.
3. The fifth patch convert ip6_sf_socklist to RCU.
ip6_sf_socklist has been protected by ipv6_mc_socklist->sflock(rwlock).
But this is already protected by RTNL So if it is converted to use RCU
in order to be used in the datapath, the sflock is no more needed.
So, its control path context can be switched to sleepable.
4. The sixth patch convert ip6_sf_list to RCU.
The reason for this patch is the same as the previous patch.
5. The seventh patch convert ifmcaddr6 to RCU.
The reason for this patch is the same as the previous patch.
6. Add new workqueues for processing query/report event.
By this patch, query and report events are processed by workqueue
So context is sleepable, not atomic.
While this logic, it acquires RTNL.
7. Add new mc_lock.
The purpose of this lock is to protect per-interface mld data.
Per-interface mld data is usually used by query/report event handler.
So, query/report event workers need only this lock instead of RTNL.
Therefore, it could reduce bottleneck.

The purpose of this lock is to avoid a bottleneck in the query/report
event handler logic.
By previous patches, almost all mld data is protected by RTNL.
So, the query and report event handler, which is data path logic
acquires RTNL too. Therefore if a lot of query and report events
are received, it uses RTNL for a long time.
So it makes the control-plane bottleneck because of using RTNL.
In order to avoid this bottleneck, mc_lock is added.
mc_lock protect only per-interface mld data and per-interface mld
data is used in the query/report event handler logic.
So, no longer rtnl_lock is needed in the query/report event handler logic.
Therefore bottleneck will be disappeared by mc_lock.

When query/report packets are received, mld module processes them.
But they are processed under BH context so it couldn't use sleepable
functions. So, in order to switch context, the two workqueues are
added which processes query and report event.
In the struct inet6_dev, mc_{query | report}_queue are added so it
is per-interface queue.
And mc_{query | report}_work are workqueue structure.
When the query or report event is received, skb is queued to proper
queue and worker function is scheduled immediately.
Workqueues and queues are protected by spinlock, which is
mc_{query | report}_lock, and worker functions are protected by RTNL.

MPTCP: Cleanup and address advertisement fixes
This patch series contains cleanup and fixes we have been testing in the
MPTCP tree. MPTCP uses TCP option headers to advertise additional
address information after an initial connection is established. The main
fixes here deal with making those advertisements more reliable and
improving the way subflows are created after an advertisement is
received.
Patches 1, 2, 4, 10, and 12 are for various cleanup or refactoring.
Patch 3 skips an extra connection attempt if there's already a subflow
connection for the newly received advertisement.
Patches 5, 6, and 7 make sure that the next address is advertised when
there are multiple addresses to share, the advertisement has been
retried, and the peer has not echoed the advertisement. Self tests are
updated.
Patches 8 and 9 fix a problem similar to 5/6/7, but covers a case where
the failure was due to a subflow connection not completing.
Patches 11 and 13 send a bare ack to revoke an advertisement rather than
waiting for other activity to trigger a packet send. This mirrors the
way acks are sent for new advertisements. Self test is included.

net: ipa: rework resource programming
This series reworks the way IPA resources are defined and
programmed. It is a little long--and I apologize for that--but
I think the patches are best taken together as a single unit.
The IPA hardware operates with a set of distinct "resources." Each
hardware instance has a fixed number of each resource type available.
Available resources are divided into smaller pools, with each pool
shared by endpoints in a "resource group." Each endpoint is thus
assigned to a resource group that determines which pools supply
resources the IPA hardware uses to handle the endpoint's processing.
The exact set of resources used can differ for each version of IPA.
Except for IPA v3.0 and v3.1, there are 5 source and 2 destination
resource types, but there's no reason to assume this won't change.
The number of resource groups used *does* typically change based on
the hardware version. For example, some versions target reduced
functionality and support fewer resource groups.
With that as background...
The net result of this series is to improve the flexibility with
which IPA resources and resource groups are defined, permitting each
version of IPA to define its own set of resources and groups. Along
the way it isolates the resource-related code, and fixes a few bugs
related to resource handling.
The first patch moves resource-related code to a new C file (and
header). It generates a checkpatch warning about updating
MAINTAINERS, which can be ignored. The second patch fixes a bug,
but the bug does not affect SDM845 or SC7180.
The third patch defines an enumerated type whose members provide
symbolic names for resource groups.
The fourth defines some resource limits for SDM845 that were not
previously being programmed. That platform "works" without this,
but to be correct, these limits should really be programmed.
The fifth patch uses a single enumerated type to define both source
and destination resource type IDs, and the sixth uses those IDs to
index the resource limit arrays. The seventh moves the definition
of that enumerated type into the platform data files, allowing each
platform to define its own set of resource types.
The eighth and ninth are fairly trivial changes. One replaces two
"max" symbols having the same value with a single symbol. And the
other replaces two distinct but otherwise identical structure types
with a single common one.
The 10th is a small preparatory patch for the 11th, passing a
different argument to a function that programs resource values.
The 11th allows the actual number of source and destination resource
groups for a platform to be specified in its configuration data.
That way the number is based on the actual number of groups defined.
This removes the need for a sort of clunky pair of functions that
defined that information previously.
Finally, the last patch just increases the number of resource groups
that can be defined to 8.

The arrays of source and destination resource limits defined in
configuration data are of a fixed size--which is the maximum number
of resource groups supported for any platform. Most platforms will
use fewer than that many groups.
Add new members to the ipa_rsrc_group_id enumerated type to define
the number of source and destination resource groups are defined for
the platform. (This type is defined for each platform in its data
file.)
Add a new field to the resource configuration data that indicates
how many of the source and destination resource groups are actually
used for the platform, and initialize it with the count value. This
allows us to determine the number of groups defined for the platform
without exposing the ipa_rsrc_group_id enumerated type.
As a result, we no longer need ipa_resource_group_src_count()
and ipa_resource_group_dst_count(), because each platform now
defines its supported number of resource groups. So get rid of
those two functions.
