80ee72e7e9 ARM: dts: sunxi: Explicitly enable pull-ups for MMC pins
In the past, all the MMC pins had

	allwinner,pull = <SUN4I_PINCTRL_NO_PULL>;

which was actually a no-op. We were relying on U-boot to set the bias
pull up for us. These properties were removed as part of the fix up to
actually support no bias on the pins. During the transition some boards
experienced regular MMC time-outs during normal operation, while others
completely failed to initialize the SD card.

Given that MMC starts in open-drain mode and the pull-ups are required,
it's best to enable it for all the pin settings.

119c366aea ARM: sunxi: Remove useless allwinner,pull property
The allwinner,pull property set to NO_PULL was really considered our
default (and wasn't even changing the default value in the code).

Remove these properties to make it obvious that we do not set anything in
such a case.

c913fc4146 ARM: SoC: late DT updates for v4.9
These updates have been kept in a separate branch mostly because
 they rely on updates to the respective clk drivers to keep the
 shared header files in sync.
 
 - The Renesas r8a7796 (R-Car M3-W) platform gets added, this is an
   automotive SoC similar to the ⅹ8a7795 chip we already support, but
   the dts changes rely on a clock driver change that has been
   merged for v4.9 through the clk tree.
 
 - The Amlogic meson-gxbb (S905) platform gains support for a few
   drivers merged through our tree, in particular the network and
   usb driver changes are required and included here, and also
   the clk tree changes.
 
 - The Allwinner platforms have seen a large-scale change to their
   clk drivers and the dts file updates must come after that.
   This includes the newly added Nextthing GR8 platform, which is
   derived from sun5i/A13.
 
 - Some integrator (arm32) changes rely on clk driver changes.
 
 - A single patch for lpc32xx has no such dependency but wasn't
   added until just before the merge window

b03e081672 ARM: sunxi: dt: Convert users to the PIO interrupts binding
The current DTs were setting the cell size to 2, but used the default xlate
function that was assuming an interrupt cell size of 1, leading to the
second part of the cell (the flags) being ignored, while we were having an
inconsistent binding between the interrupts and gpio (that could also be
used as interrupts).

That "binding" doesn't work either with newer SoCs that have multiple irq
banks.

Now that we fixed the pinctrl driver to handle this like it should always
have been handled, convert the DT users, and while we're at it, remove the
size-cells property of PIO that is completely useless.

3a2bc642ab ARM: dts: sun6i: Add cpu clock reference and operating points to dtsi
The cpu core is clocked from the "cpu" clock. Add a reference to it
in the first cpu node. Also add "cpu0" label to the node.

The operating points were taken from the a list compiled by Maxime Ripard,
which is based on A31 FEX files from the sunxi-boards repository. Not all
boards have the same settings. The settings in this patch are the ones
shared by A/B/C revisions, plus the default clock setting from u-boot.

4c1bb9c318 ARM: dts: sunxi: Add address- and size-cells properties to the mmc ctrl nodes
Sometimes we need to specify non-probably information for sdio devices in the
devicetree, this is done through child nodes addressed by the reg property,
whereby the reg property refers to the sdio function number, see;
Documentation/devicetree/bindings/mmc/mmc.txt

This commit adds the necessary address- and size-cells properties to the mmc
controller nodes in the dtsi files, so that dts files needing such a child
node do not need to specify these themselves.

18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

a233bb742a ARM: SoC DT updates
DT changes continue to be the bulk of our merge window contents.
 
 We continue to have a large set of changes across the board as new platforms
 and drivers are added.
 
 Some of the new platforms are:
 - Alphascale ASM9260
 - Marvell Armada 388
 - CSR Atlas7
 - TI Davinci DM816x
 - Hisilicon HiP01
 - ST STiH418
 
 There have also been some sweeping changes, including relicensing of DTS
 contents from GPL to GPLv2+/X11 so that the same files can be reused in
 other non-GPL projects more easily. There's also been changes to the
 DT Makefile to make it a little less conflict-ridden and churny down
 the road.

Review of the u-boot sunxi simplefb patches has led to the decision that
u-boot should not use a specific path to find the nodes as this goes contrary
to how devicetree usually works.

Instead a platform specific compatible + properties should be used for this.

The simplefb bindings have already been updated to reflect this, this patch
brings the sunxi devicetree files in line with the new binding, and the
actual u-boot implementation as it is going upstream.
