This backports multiple patches from kernel 4.10 which are adding
missing support for the A64 and the pine64 board. These are the device
tree files, the pinctlk and the clock driver.

+Subject: arm64: sunxi: always enable reset controller
+
+The sunxi clk driver causes a link error when the reset controller
+subsystem is disabled:
+
+drivers/clk/built-in.o: In function `sun4i_ve_clk_setup':
+:(.init.text+0xd040): undefined reference to `reset_controller_register'
+drivers/clk/built-in.o: In function `sun4i_a10_display_init':
+:(.init.text+0xe5e0): undefined reference to `reset_controller_register'
+drivers/clk/built-in.o: In function `sunxi_usb_clk_setup':
+:(.init.text+0x10074): undefined reference to `reset_controller_register'
+
+We already force it to be enabled on arm32 and some other arm64 platforms,
+but not on arm64/sunxi. This adds the respective Kconfig statements to
+also select it here.

+Subject: clk: sunxi-ng: Remove the use of rational computations
+
+While the rational library works great, it doesn't really allow us to add
+more constraints, like the minimum.
+
+Remove that in order to be able to deal with the constraints we'll need.

+Subject: clk: sunxi-ng: Finish to convert to structures for arguments
+
+Some clocks still use an explicit list of arguments, which make it a bit
+more tedious to add new parameters.
+
+Convert those over to a structure pointer argument to add as many
+arguments as possible without having to many noise in our patches, or a
+very long list of arguments.

+Subject: arm64: dts: add Allwinner A64 SoC .dtsi
+
+The Allwinner A64 SoC is a low-cost chip with 4 ARM Cortex-A53 cores
+and the typical tablet / TV box peripherals.
+The SoC is based on the (32-bit) Allwinner H3 chip, sharing most of
+the peripherals and the memory map.
+Although the cores are proper 64-bit ones, the whole SoC is actually
+limited to 4GB (including all the supported DRAM), so we use 32-bit
+address and size cells. This has the nice feature of us being able to
+reuse the DT for 32-bit kernels as well.
+This .dtsi lists the hardware that we support so far.

+Subject: arm64: dts: add Pine64 support
+
+The Pine64 is a cost-efficient development board based on the
+Allwinner A64 SoC.
+There are three models: the basic version with Fast Ethernet and
+512 MB of DRAM (Pine64) and two Pine64+ versions, which both
+feature Gigabit Ethernet and additional connectors for touchscreens
+and a camera. Or as my son put it: "Those are smaller and these are
+missing." ;-)
+The two Pine64+ models just differ in the amount of DRAM
+(1GB vs. 2GB). Since U-Boot will figure out the right size for us and
+patches the DT accordingly we just need to provide one DT for the
+Pine64+.

+Subject: arm64: dts: fix build errors from missing dependencies
+
+Two branches were incorrectly sent without having the necessary
+header file changes. Rather than back those out now, I'm replacing
+the symbolic names for the clks and resets with the numeric
+values to get 'make allmodconfig dtbs' back to work.
+
+After the header file changes are merged, we can revert this
+patch.
+
+Fixes: 6bc37fa ("arm64: dts: add Allwinner A64 SoC .dtsi")
+Fixes: 50784e6 ("dts: arm64: db820c: add pmic pins specific dts file")

+Subject: pinctrl: sunxi: Rework the pin config building code
+
+In order to support more easily the generic pinctrl properties, rework the
+pinctrl maps configuration and split it into several sub-functions.
+
+One of the side-effects from that rework is that we only parse the pin
+configuration once, since it's going to be common to every pin, instead of
+having to parsing once for each pin.

+Subject: pinctrl: sunxi: Handle bias disable
+
+So far, putting NO_PULL in allwinner,pull was ignored, behaving like if
+that property was not there at all.
+
+Obviously, this is not the right thing to do, and in that case, we really
+need to just disable the bias.

+Subject: pinctrl: sunxi: Support generic binding
+
+Our bindings are mostly irrelevant now that we have generic pinctrl
+bindings that cover exactly the same uses cases.
+
+Add support for the new ones, and obviously keep our old binding support in
+order to keep the ABI stable.

+Subject: pinctrl: sunxi: make bool drivers explicitly non-modular
+
+None of the Kconfigs for any of these drivers are tristate,
+meaning that they currently are not being built as a module by anyone.
+
+Lets remove the modular code that is essentially orphaned, so that
+when reading the drivers there is no doubt they are builtin-only.  All
+drivers get essentially the same change, so they are handled in batch.
+
+Changes are (1) use builtin_platform_driver, (2) use init.h header
+(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
+and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.
+
+Since module_platform_driver() uses the same init level priority as
+builtin_platform_driver() the init ordering remains unchanged with
+this commit.
+
+Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
+
+We do delete the MODULE_LICENSE etc. tags since all that information
+is already contained at the top of each file in the comments.

+Subject: pinctrl: sunxi: Free configs in pinctrl_map only if it is a config
+ map
+
+In the recently refactored sunxi pinctrl library, we are only allocating
+one set of pin configs for each pinmux setting node. When the pinctrl_map
+structure is freed, the pin configs should also be freed. However the
+code assumed the first map would contain the configs, which actually
+never happens, as the mux function map gets added first.
+
+The proper way to do this is to look through all the maps and free the
+first one whose type is actually PIN_MAP_TYPE_CONFIGS_GROUP.
+
+Also slightly expand the comment explaining this.

+Subject: pinctrl: sunxi: Fix PIN_CONFIG_BIAS_PULL_{DOWN,UP} argument
+
+According to pinconf-generic.h, the argument for
+PIN_CONFIG_BIAS_PULL_{DOWN,UP} is non-zero if the bias is enabled
+with a pull up/down resistor, zero if it is directly connected
+to VDD or ground.
+
+Since Allwinner hardware uses a weak pull resistor internally,
+the argument should be 1.

+Subject: pinctrl: sunxi: Add support for fetching pinconf settings from
+ hardware
+
+The sunxi pinctrl driver only caches whatever pinconf setting was last
+set on a given pingroup. This is not particularly helpful, nor is it
+correct.
+
+Fix this by actually reading the hardware registers and returning
+the correct results or error codes. Also filter out unsupported
+pinconf settings. Since this driver has a peculiar setup of 1 pin
+per group, we can support both pin and pingroup pinconf setting
+read back with the same code. The sunxi_pconf_reg helper and code
+structure is inspired by pinctrl-msm.
+
+With this done we can also claim to support generic pinconf, by
+setting .is_generic = true in pinconf_ops.
+
+Also remove the cached config value. The behavior of this was never
+correct, as it only cached 1 setting instead of all of them. Since
+we can now read back settings directly from the hardware, it is no
+longer required.

+chance to rework sunxi_pconf_group_set to have it match the structure
+of sunxi_pconf_(group_)get and make it easier to understand.
+
+For each config to set, it:
+
+    1. checks if the parameter is supported.
+    2. checks if the argument is within limits.
+    3. converts argument to the register value.
+    4. writes to the register with spinlock held.
+
+As a result the function now blocks unsupported config parameters,
+instead of silently ignoring them.

+Subject: pinctrl: sunxi: Add support for interrupt debouncing
+
+The pin controller found in the Allwinner SoCs has support for interrupts
+debouncing.
+
+However, this is not done per-pin, preventing us from using the generic
+pinconf binding for that, but per irq bank, which, depending on the SoC,
+ranges from one to five.
+
+Introduce a device-wide property to deal with this using a microsecond
+resolution. We can re-use the per-pin input-debounce property for that, so
+let's do it!

+Subject: pinctrl: sunxi: fix theoretical uninitialized variable access
+
+gcc warns about a  way that it could use an uninitialized variable:
+
+drivers/pinctrl/sunxi/pinctrl-sunxi.c: In function 'sunxi_pinctrl_init':
+drivers/pinctrl/sunxi/pinctrl-sunxi.c:1191:8: error: 'best_div' may be used uninitialized in this function [-Werror=maybe-uninitialized]
+
+This cannot really happen except if 'freq' is UINT_MAX and 'clock' is
+zero, and both of these are forbidden. To shut up the warning anyway,
+this changes the logic to initialize the return code to the first
+divider value before looking at the others.

+Subject: pinctrl: sunxi: Don't enforce bias disable (for now)
+
+Commit 07fe64ba213f ("pinctrl: sunxi: Handle bias disable") actually
+enforced enforced the disabling of the pull up/down resistors instead of
+ignoring it like it was done before.
+
+This was part of a wider rework to switch to the generic pinconf bindings,
+and was meant to be merged together with DT patches that were switching to
+it, and removing what was considered default values by both the binding and
+the boards. This included no bias on a pin.
+
+However, those DT patches were delayed to 4.11, which would be fine only
+for a significant number boards having the bias setup wrong, which in turns
+break the MMC on those boards (and possibly other devices too).
+
+In order to avoid conflicts as much as possible, bring back the old
+behaviour for 4.10, and we'll revert that commit once all the DT bits will
+have landed.
