+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.

+Remove that in order to be able to deal with the constraints we'll need.

+
+Some clocks still use an explicit list of arguments, which make it a bit

+
+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")

+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.

+
+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.

+
+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,

+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.

+Subject: pinctrl: sunxi: Make sunxi_pconf_group_set use sunxi_pconf_reg helper
+
+The sunxi_pconf_reg helper introduced in the last patch gives us the
+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: Testing the wrong variable
+
+Smatch complains that we dereference "map" before testing it for NULL
+which is true. We should be testing "*map" instead. Also on the error
+path, we should free *map and set it to NULL.

+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.
