Youri Querry 9a499cc1e7 soc: fsl: dpio: Adding QMAN multiple enqueue interface.
Update of QMAN the interface to enqueue frame. We now support multiple
enqueue (qbman_swp_enqueue_multiple) and multiple enqueue with
a table of descriptor (qbman_swp_enqueue_multiple_desc).

Laurentiu Tudor 4100f962d8 soc/fsl/qbman_portals: add APIs to retrieve the probing status
Add a couple of new APIs to check the probing status of the required
cpu bound qman and bman portals:
 'int bman_portals_probed()' and 'int qman_portals_probed()'.
They return the following values.
 *  1 if qman/bman portals were all probed correctly
 *  0 if qman/bman portals were not yet probed
 * -1 if probing of qman/bman portals failed
Portals are considered successful probed if no error occurred during
the probing of any of the portals and if enough portals were probed
to have one available for each cpu.
The error handling paths were slightly rearranged in order to fit this
new functionality without being too intrusive.
Drivers that use qman/bman portal driver services are required to use
these APIs before calling any functions exported by these drivers or
otherwise they will crash the kernel.
First user will be the dpaa1 ethernet driver, coming in a subsequent
patch.

Mauro Carvalho Chehab 4d2e26a38f docs: powerpc: convert docs to ReST and rename to *.rst
Convert docs to ReST and add them to the arch-specific
book.

The conversion here was trivial, as almost every file there
was already using an elegant format close to ReST standard.

The changes were mostly to mark literal blocks and add a few
missing section title identifiers.

One note with regards to "--": on Sphinx, this can't be used
to identify a list, as it will format it badly. This can be
used, however, to identify a long hyphen - and "---" is an
even longer one.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

Automatically add a device link between the actual device requesting the
dpaa2_io_service_register and the underlying dpaa2_io used. This link
will ensure that when a DPIO device, which is indirectly used by other
devices, is unbound any consumer devices will be also unbound from their
drivers.

For example, any DPNI, bound to the dpaa2-eth driver, which is using
DPIO devices will be unbound before its supplier device.

Also, add a new parameter to the dpaa2_io_service_[de]register functions
to specify the requesting device (ie the consumer).

Ioana Ciornei 991e873223 soc: fsl: dpio: use a cpumask to identify which cpus are unused
The current implementation of the dpio driver uses a static next_cpu
variable to keep track of the index of the next cpu available. This
approach does not handle well unbinding and binding dpio devices in a
random order. For example, unbinding a dpio and then binding it again
with the driver, will generate the below error:

$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/unbind
$ echo dpio.5 > /sys/bus/fsl-mc/drivers/fsl_mc_dpio/bind
[  103.946380] fsl_mc_dpio dpio.5: probe failed. Number of DPIOs exceeds
NR_CPUS.
[  103.955157] fsl_mc_dpio dpio.5: fsl_mc_driver_probe failed: -34
-bash: echo: write error: No such device

Fix this error by keeping a global cpumask of unused cpus that will be
updated at every dpaa2_dpio_[probe,remove].

Linus Torvalds b22b6beae6 ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include:
 
 - The TEE subsystem gains an in-kernel interface to access the TEE
   from device drivers.
 
 - The reset controller subsystem gains a driver for the Qualcomm
   Snapdragon 845 Power Domain Controller.
 
 - The Xilinx Zynq platform now has a firmware interface for its
   platform management unit. This contains a firmware "ioctl" interface
   that was a little controversial at first, but the version we merged
   solved that by not exposing arbitrary firmware calls to user space.
 
 - The Amlogic Meson platform gains a "canvas" driver that is used
   for video processing and shared between different high-level drivers.
 
 The rest is more of the usual, mostly related to SoC specific power
 management support and core drivers in drivers/soc:
 
 - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new
   features related to power and reset control.
 
 - The Mediatek mt8183 and mt6765 SoC platforms gain support for
   their respective power management chips.
 
 - A new driver for NXP i.MX8, which need a firmware interface for
   power management.
 
 - The SCPI firmware interface now contains support estimating power
   usage of performance states
 
 - The NVIDIA Tegra "pmc" driver gains a few new features, in particular
   a pinctrl interface for configuring the pads.
 
 - Lots of small changes for Qualcomm, in particular the "smem"
   device driver.
 
 - Some cleanups for the TI OMAP series related to their sysc
   controller.
 
 Additional cleanups and bugfixes in SoC specific drivers include the
 Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Roy Pledge c89105c9b3 staging: fsl-mc: Move DPIO from staging to drivers/soc/fsl
Move the NXP DPIO (Datapath I/O Driver) out of the
drivers/staging directory and into the drivers/soc/fsl directory.

The DPIO driver enables access to Queue and Buffer Manager (QBMAN)
hardware on NXP DPAA2 devices. This is a prerequisite to moving the
DPAA2 Ethernet driver out of staging.

Holger Brunck 067bb938da net/wan/fsl_ucc_hdlc: add hdlc-bus support
This adds support for hdlc-bus mode to the fsl_ucc_hdlc driver. This can
be enabled with the "fsl,hdlc-bus" property in the DTS node of the
corresponding ucc.

This aligns the configuration of the UPSMR and GUMR registers to what is
done in our ucc_hdlc driver (that only support hdlc-bus mode) and with
the QuickEngine's documentation for hdlc-bus mode.

GUMR/SYNL is set to AUTO for the busmode as in this case the CD signal
is ignored. The brkpt_support is enabled to set the HBM1 bit in the
CMXUCR register to configure an open-drain connected HDLC bus.

Merge tag 'powerpc-4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

Pull more powerpc updates from Michael Ellerman:
 "The change to the Linux page table geometry was delayed for more
  testing with 16G pages, and there's the new CPU features stuff which
  just needed one more polish before going in. Plus a few changes from
  Scott which came in a bit late. And then various fixes, mostly minor.

  Summary highlights:

   - rework the Linux page table geometry to lower memory usage on
     64-bit Book3S (IBM chips) using the Hash MMU.

   - support for a new device tree binding for discovering CPU features
     on future firmwares.

   - Freescale updates from Scott:
