This patch adds support for TI divider clock binding, which simply uses
the basic clock divider to provide the features needed.

975e15487d clk: ti: add composite clock support
This is a multipurpose clock node, which contains support for multiple
sub-clocks. Uses basic composite clock type to implement the actual
functionality, and TI specific gate, mux and divider clocks.

b1a07b478b CLK: TI: add autoidle support
TI clk driver now routes some of the basic clocks through own
registration routine to allow autoidle support. This routine just
checks a couple of device node properties and adds autoidle support
if required, and just passes the registration forward to basic clocks.

ba52f8a986 clk/zynq/clkc: Add 'fclk-enable' feature
In some use cases Zynq's FPGA clocks are used as static clock
generators for IP in the FPGA part of the SOC for which no Linux driver
exists and would control those clocks. To avoid automatic
gating of these clocks in such cases a new property - fclk-enable - is
added to the clock controller's DT description to accomodate such use
cases. It's value is a bitmask, where a set bit results in enabling
the corresponding FCLK through the clkc.

FPGA clocks are handled following the rules below:

If an FCLK is not enabled by bootloaders, that FCLK will be disabled in
Linux. Drivers can enable and control it through the CCF as usual.

If an FCLK is enabled by bootloaders AND the corresponding bit in the
'fclk-enable' DT property is set, that FCLK will be enabled by the clkc,
resulting in an off by one reference count for that clock. Ensuring it
will always be running.

Pull networking fixes from David Miller:

 1) Revert CHECKSUM_COMPLETE optimization in pskb_trim_rcsum(), I can't
    figure out why it breaks things.

 2) Fix comparison in netfilter ipset's hash_netnet4_data_equal(), it
    was basically doing "x == x", from Dave Jones.

 3) Freescale FEC driver was DMA mapping the wrong number of bytes, from
    Sebastian Siewior.

 4) Blackhole and prohibit routes in ipv6 were not doing the right thing
    because their ->input and ->output methods were not being assigned
    correctly.  Now they behave properly like their ipv4 counterparts.
    From Kamala R.

 5) Several drivers advertise the NETIF_F_FRAGLIST capability, but
    really do not support this feature and will send garbage packets if
    fed fraglist SKBs.  From Eric Dumazet.

 6) Fix long standing user triggerable BUG_ON over loopback in RDS
    protocol stack, from Venkat Venkatsubra.

 7) Several not so common code paths can potentially try to invoke
    packet scheduler actions that might be NULL without checking.  Shore
    things up by either 1) defining a method as mandatory and erroring
    on registration if that method is NULL 2) defininig a method as
    optional and the registration function hooks up a default
    implementation when NULL is seen.  From Jamal Hadi Salim.

 8) Fix fragment detection in xen-natback driver, from Paul Durrant.

 9) Kill dangling enter_memory_pressure method in cg_proto ops, from
    Eric W Biederman.

10) SKBs that traverse namespaces should have their local_df cleared,
    from Hannes Frederic Sowa.

11) IOCB file position is not being updated by macvtap_aio_read() and
    tun_chr_aio_read().  From Zhi Yong Wu.

12) Don't free virtio_net netdev before releasing all of the NAPI
    instances.  From Andrey Vagin.

13) Procfs entry leak in xt_hashlimit, from Sergey Popovich.

14) IPv6 routes that are no cached routes should not count against the
    garbage collection limits.  We had this almost right, but were
    missing handling addrconf generated routes properly.  From Hannes
    Frederic Sowa.

15) fib{4,6}_rule_suppress() have to consider potentially seeing NULL
    route info when they are called, from Stefan Tomanek.

16) TUN and MACVTAP have had truncated packet signalling for some time,
    fix from Jason Wang.

17) Fix use after frrr in __udp4_lib_rcv(), from Eric Dumazet.

18) xen-netback does not interpret the NAPI budget properly for TX work,
    fix from Paul Durrant.

added minimal device tree support to smc91x, but it's not working on

Fix the issue by parsing the necessary configuration like the
smc911x driver is doing. As most smc91x users seem to use 16-bit
access, let's default to that if no reg-io-width is specified.

dd0df47dc3 net: davinci_emac: Fix platform data handling and make usable for am3517
When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.

Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.

Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to
new mdio).

36059ee2ba ARM: SoC fixes for 3.13-rc
Another batch of fixes for ARM SoCs for 3.13. The diffstat is large,
 mostly because of:
 
 - Another set of fixes to fix regressions caused by moving OMAP from board
   files to DT. Tony thinks this was the last major set of fixes, with
   maybe just a few small patches to follow.
 - More fixes for Marvell platforms, most dealing with misdescribed PCIe
   hardware, i.e. incorrect number of busses on some SoCs, etc. The line
   delta adds up due to various ranges moving around when this is fixed.
 
 But there's also:
 
 - Some smaller tweaks to defconfigs to make more boards bootable in my
   test setup for better coverage.
 - There are also a few other smaller fixes, a short series for at91, a couple
   of reverts for ux500, etc.

b8be3a2279 Merge tag 'omap-for-v3.13/fixes-against-rc1-take2' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into fixes
From Tony Lindgren:

Some omap related fixes that have come up with people moving to device
tree only based booting for omap2+.

The series contains a handful of fixes for the igep boards as they were
one of the first omap3 boards to jump over completely to device tree
based booting. So these can be considered regressions compared to
booting igep in legacy mode with board files in v3.12.

Also included are few other device tree vs legacy booting regressions:

- yet more missing omap3 .dtsi entries that have showed up booting
  various boards with device tree only

- n900 eMMC device tree fix

- fixes for beagle USB EHCI

- two fixes to make omap2420 MMC work

As we're moving omap2+ to be device tree only for v3.14, I'd like to
have v3.13 work equally well for legacy based booting and device tree
based booting. So there will be likely few more device tree related
booting patches trickling in.

This series also includes a regression fix for the omap timer posted
mode that may wrongly stay on from the bootloader for some SoCs.

9cb238c00b mmc: omap: Fix I2C dependency and make driver usable with device tree
Some features can be configured by the companion I2C chips,
which may not be available at the probe time. Fix the issue
by returning -EPROBE_DEFER when the MMC controller slots
are not configured.

While at it, let's also add minimal device tree support so
omap24xx platforms can use this driver without legacy mode
since we claim to support device tree for mach-omap2 based
systems.

Although adding the minimal device tree support is not strictly
a fix, it does remove one of the last blockers for dropping a
bunch of legacy platform data for mach-omap2.

0e4b0743bb ARM: SoC fixes for 3.13-rc
Mostly bugfixes and a few small code removals. Worth pointing out is:
 
 - A handful of more fixes to get DT enablement working properly on OMAP,
   finding new breakage of things that don't work quite right yet without
   the traditional board files. I expect a bit more of this to come in this
   release as people test on their hardware.
 - Implementation of power_down_finish() on vexpress, to make kexec work and
   to stop the MCPM core to produce a warning (the warning was new to 3.13-rc1).
 - A handful of minor fixes for various platforms.
