Alexander Kochetkov 94bbdd7724 ARM: dts: rockchip: setup DMA-channels for mmc0 and emmc for rk3188
This commit enable DMA-based transfers for SD/eMMC card adapters
and reduce number of interrupts produced by SD-card/eMMC-card
adapters.

Sometimes interrupts from SD-card/eMMC-card adapters running in
PIO mode blocks execution of hrtimers and I2S DMA callbacks for
a long periods (100 ms or more).

Heiko Stuebner 2e1aa605fa ARM: dts: rockchip: fix PPI misconfiguration on Cortex-A9 socs
According to [0] pointed out by Marc Zyngier in a report about a
similar error message, PPIs 11 and 13 are edge triggered on
Cortex-A9 socs including the rk3066 and rk3188 which currently
mark them as level triggered.

Until some time ago the gic did not care but commit 992345a58e
("irqchip/gic: WARN if setting the interrupt type for a PPI fails")
introduced a warning for that case.

Fix the warning on these socs by describing the interrupts correctly
and also using the binding constants for easier reading in the future.

Linus Torvalds 786a72d791 ARM: DT updates for v4.10
Lots of changes as usual, so I'm trying to be brief here. Most of the
 new hardware support has the respective driver changes merged through
 other trees or has had it available for a while, so this is where things
 come together.
 
 We get a DT descriptions for a couple of new SoCs, all of them variants
 of other chips we already support, and usually coming with a new
 evaluation board:
 
 - Oxford semiconductor (now Broadcom) OX820 SoC for NAS devices
 - Qualcomm MDM9615 LTE baseband
 - NXP imx6ull, the latest and smallest i.MX6 application processor variant
 - Renesas RZ/G (r8a7743 and r8a7745) application processors
 - Rockchip PX3, a variant of the rk3188 chip used in Android tablets
 - Rockchip rk1108 single-core application processor
 - ST stm32f746 Cortex-M7 based microcontroller
 - TI DRA71x automotive processors
 
 These are commercially available consumer platforms we now support:
 - Motorola Droid 4 (xt894) mobile phone
 - Rikomagic MK808 Android TV stick based on Rockchips rx3066
 - Cloud Engines PogoPlug v3 based on OX820
 - Various Broadcom based wireless devices:
   - Netgear R8500 router
   - Tenda AC9 router
   - TP-LINK Archer C9 V1
   - Luxul XAP-1510 Access point
 - Turris Omnia open hardware router based on Armada 385
 
 And a couple of new boards targeted at developers, makers
 or industrial integration:
 - Macnica Sodia development platform for Altera socfpga (Cyclone V)
 - MicroZed board based on Xilinx Zynq FPGA platforms
 - TOPEET itop/elite based on exynos4412
 - WP8548 MangOH Open Hardware platform for IOT, based on
   Qualcomm MDM9615
 - NextThing CHIP Pro gadget
 - NanoPi M1 development board
 - AM571x-IDK industrial board based on TI AM5718
 - i.MX6SX UDOO Neo
 - Boundary Devices Nitrogen6_SOM2 (i.MX6)
 - Engicam i.CoreM6
 - Grinn i.MX6UL liteSOM/liteBoard
 - Toradex Colibri iMX6 module
 
 Other changes:
 - added peripherals on renesas, davinci, stm32f429, uniphier, sti,
   mediatek, integrator, at91, imx, vybrid, ls1021a, omap, qualcomm,
   mvebu, allwinner, broadcom, exynos, zynq
 
 - Continued fixes for W=1 dtc warnings
 
 - The old STiH415/416 SoC support gets removed, these never made it into
   products and have served their purpose in the kernel as a template
   for teh newer chips from ST
 
 - The exynos4415 dtsi file is removed as nothing uses it.
 
 - Intel PXA25x can now be booted using devicetree
 
 Conflicts:
 arch/arm/boot/dts/r8a*.dtsi: a node was added
 the clk tree, keep both sides and watch out for git
 dropping the required '};' at the end of each side.

The skeleton.dtsi file was removed in ARM64 for different reasons as
explained in commit ("3ebee5a2e141 arm64: dts: kill skeleton.dtsi").

These also applies to ARM and it will also allow to get rid of the
following DTC warnings in the future:

"Node /memory has a reg or ranges property, but no unit name"

The disassembled DTB are almost the same, besides empty chosen nodes
being removed. So the change should not have a functional impact.

   1) By far the biggest accomplishment, thanks to a large range of
      contributors, is the addition of multi-send for transmit.  This is
      the result of discussions back in Chicago, and the hard work of
      several individuals.

      Now, when the ->ndo_start_xmit() method of a driver sees
      skb->xmit_more as true, it can choose to defer the doorbell
      telling the driver to start processing the new TX queue entires.

      skb->xmit_more means that the generic networking is guaranteed to
      call the driver immediately with another SKB to send.

      There is logic added to the qdisc layer to dequeue multiple
      packets at a time, and the handling mis-predicted offloads in
      software is now done with no locks held.

      Finally, pktgen is extended to have a "burst" parameter that can
      be used to test a multi-send implementation.

      Several drivers have xmit_more support: i40e, igb, ixgbe, mlx4,
      virtio_net

      Adding support is almost trivial, so export more drivers to
      support this optimization soon.

      I want to thank, in no particular or implied order, Jesper
      Dangaard Brouer, Eric Dumazet, Alexander Duyck, Tom Herbert, Jamal
      Hadi Salim, John Fastabend, Florian Westphal, Daniel Borkmann,
      David Tat, Hannes Frederic Sowa, and Rusty Russell.

   2) PTP and timestamping support in bnx2x, from Michal Kalderon.

   3) Allow adjusting the rx_copybreak threshold for a driver via
      ethtool, and add rx_copybreak support to enic driver.  From
      Govindarajulu Varadarajan.

   4) Significant enhancements to the generic PHY layer and the bcm7xxx
      driver in particular (EEE support, auto power down, etc.) from
      Florian Fainelli.

   5) Allow raw buffers to be used for flow dissection, allowing drivers
      to determine the optimal "linear pull" size for devices that DMA
      into pools of pages.  The objective is to get exactly the
      necessary amount of headers into the linear SKB area pre-pulled,
      but no more.  The new interface drivers use is eth_get_headlen().
      From WANG Cong, with driver conversions (several had their own
      by-hand duplicated implementations) by Alexander Duyck and Eric
      Dumazet.

   6) Support checksumming more smoothly and efficiently for
      encapsulations, and add "foo over UDP" facility.  From Tom
      Herbert.

   7) Add Broadcom SF2 switch driver to DSA layer, from Florian
      Fainelli.

   8) eBPF now can load programs via a system call and has an extensive
      testsuite.  Alexei Starovoitov and Daniel Borkmann.

   9) Major overhaul of the packet scheduler to use RCU in several major
      areas such as the classifiers and rate estimators.  From John
      Fastabend.

  10) Add driver for Intel FM10000 Ethernet Switch, from Alexander
      Duyck.

  11) Rearrange TCP_SKB_CB() to reduce cache line misses, from Eric
      Dumazet.

  12) Add Datacenter TCP congestion control algorithm support, From
      Florian Westphal.

  13) Reorganize sk_buff so that __copy_skb_header() is significantly
      faster.  From Eric Dumazet"
