The Fully-Programmable Input/Output Array (FPIOA) device controls pin
multiplexing on the K210. The FPIOA can remap any supported function to any
multifunctional IO pin. It can also perform basic GPIO functions, such as
reading the current value of a pin. However, GPIO functionality remains
largely unimplemented (in favor of the dedicated GPIO peripherals).

This extends the pinctrl-sandbox driver to support pin muxing, and adds a
test for that behaviour. The test is done in C and not python (like the
existing tests for the pinctrl uclass) because it needs to call
pinctrl_select_state. Another option could be to add a command that
invokes pinctrl_select_state and then test everything in
test/py/tests/test_pinmux.py.
The pinctrl-sandbox driver now mimics the way that many pinmux devices
work. There are two groups of pins which are muxed together, as well as
four pins which are muxed individually. I have tried to test all normal
paths. However, very few error cases are explicitly checked for.

The pinmux property allows for smaller and more compact device trees,
especially when there are many pins which need to be assigned individually.
Instead of specifying an array of strings to be parsed as pins and a
function property, the pinmux property contains an array of integers
representing pinmux groups. A pinmux group consists of the pin identifier
and mux settings represented as a single integer or an array of integers.
Each individual pin controller driver specifies the exact format of a
pinmux group. As specified in the Linux documentation, a pinmux group may
be multiple integers long. However, no existing drivers use multi-integer
pinmux groups, so I have chosen to omit this feature. This makes the
implementation easier, since there is no need to allocate a buffer to do
endian conversions.
Support for the pinmux property is done differently than in Linux. As far
as I can tell, inversion of control is used when implementing support for
the pins and groups properties to avoid allocating. This results in some
duplication of effort; every property in a config node is parsed once for
each pin in that node. This is not such an overhead with pins and groups
properties, since having multiple pins in one config node does not occur
especially often. However, the semantics of the pinmux property make such a
configuration much more appealing. A future patch could parse all config
properties at once and store them in an array. This would make it easier to
create drivers which do not function solely as callbacks from
pinctrl-generic.
This commit increases the size of the sandbox build by approximately 48
bytes. However, it also decreases the size of the K210 device tree by 2
KiB from the previous version of this series.
The documentation has been updated from the last Linux commit before it was
split off into yaml files.

Commit-notes:
Open questions / discussion:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This should be removed if all boards are converted to
DM/DTS.
- Unfortunately linux DTS does not use "pinctrl-"
properties, instead "pio-handle" properties.
Even worser old U-Boot code initializes all pins
defined in "const qe_iop_conf_t qe_iop_conf_tab[]"
table in board code. As linux does the same I decided
to also scan through all subnodes containing "pio-map"
property and initialize them too.
The proper solution would be to check for "pio-handle"
when a device is probed.

Currently when using OF_PLATDATA the binding between devices and drivers
is done trying to match the compatible string in the node with a driver
name. However, usually a single driver supports multiple compatible strings
which causes that only devices which its compatible string matches a
driver name get bound.
To overcome this issue, this patch adds the U_BOOT_DRIVER_ALIAS macro,

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.
Move the compatibility features into a separate header file.

At present devres.h is included in all files that include dm.h but few

As well as a pinctrl driver this provides a GPIO driver based on the same

In the Linux pinctrl binding, the pin configuration nodes don't need to
be direct children of the pin controller device (may be grandchildren for
example). This behavior is managed with the pinconfig u-class which
recursively bind all the sub-node of the pin controller.
But for some binding (when pin configuration is only children of pin
controller) that is not necessary. U-Boot can save memory and reduce
the number of pinconf instance when this feature is deactivated
(for arch stm32mp for example for SPL).
This patch allows to control this feature with a new option
CONFIG_PINCONF_RECURSIVE when it is possible for each individual

In spite of the summary line, U-Boot commits [1-2] seem to have
aligned the U-Boot PFC tables to Linux v5.1 rather than to v5.0, since
they also imported the Linux 5.1 commits listed in [3].
What current commit tries to accomplish is to align the Gen2 and Gen3
pinctrl tables to Linux v5.2. Importing these updates in two steps
as done before (i.e. separately for Gen2 and Gen3) is somewhat difficult
due to Linux commits like [5-6] which atomically update both Gen2/3
platforms and whose breakdown would not be easily possible.
The detailed list of Linux commits squashed into this U-Boot patch is
shown in [4]. The second column in [4] depicts the patch id mismatch
between the original Linux and the resulted U-Boot commit. The
exclamation mark means that manual conflict resolution was involved
during cherry picking Linux commit into U-Boot repository (this is
mainly caused by dropped changes in files like pfc-r8a7795-es1.c and
pfc-r8a77980.c which are missing in U-Boot).

This commit is necessary to be able to re-use the pinctrl code in early
SPL to properly configure pins.
The problem is that those "static" structures (without explicit
initialization) are placed in the SDRAM area, which corresponds to
u-boot proper (not even SPL).
Hence, when one wants to configure pins before relocation via DTS/DM,
the board hangs (imx6q SoC powered one) as only OCRAM area is available
(0x009xxxxx).
This commit prevents from this issue by moving the imx6_pinctrl_soc_info
structure to data section (from BSS).

This reverts commit a7f4b4b344.
As reported by Alex Kiernan the above optimization introduces a
regression in the below use case where:
1. Device has defined 'u-boot,dm-spl' property (@ eMMC DTS node)
2. The device downloads its MLO/SPL via UART (not eMMC - the eMMC pinmux
pins are NOT probed/configured in MLO/SPL).
3. The loaded via UART MLO/SPL wants to load Linux from eMMC. In this case
the DM core and pinctrl uclass checks 'u-boot,dm-spl' and don't
configure pins (as it thinks that those were initialized in MLO/SPL).
As we are very close to release - please revert this commit.

The current pinctrl driver for the RK3399 has a range of qulity issues.
E.g. it only implements the .set_state_simple() callback, it
does not parse the available pinctrl information from the DTS
(instead uses hardcoded values), is not flexible enough to cover
devices without 'interrupt' field in the DTS (e.g. PWM),
is not written generic enough to make code reusable among other
rockchip SoCs...
This patch addresses these issues by reimplementing the whole driver
from scratch using the .set_state() callback.
The new implementation covers all featurese of the old code
(i.e. it supports pinmuxing and pullup/pulldown configuration).
This patch has been tested on a RK3399-Q7 SoM (Puma).

This commit prevents from re-configuring pins if those were configured

Some pins - like UART or DDR must be setup before relocation

change, those pins are re-configured after relocation (pre_reloc_only = 0,
so we do not "continue").
Such behavior may be a problem for DDR PAD configuration, as they might

Merge tag 'u-boot-amlogic-20181207' of git://git.denx.de/u-boot-amlogic
Two fixes for the Amlogic Pinctrl driver :
- bad usage of clrsetbits_le32
- bad pin definition for AXG Family
Due to gpio holes management, stm32_pinctrl_get_gpio_dev() must
be updated.
stm32_pinctrl_get_gpio_dev() returns from a given pin selectors
the corresponding bank gpio device and the gpio_offset inside this
gpio bank.
Update also all functions which makes usage of stm32_pinctrl_get_gpio_dev.

Move gpio_dev list filling outside probe() to speed-up U-boot
boot sequence execution. This list is populated only when needed.

The pin number (first and last) in the bank definition is missing the
pin base offset shifting. This is causing a miscalculation when
retrieving the register and pin offsets in the GPIO driver causing the
'gpio' command to drive the wrong pins / GPIOs in the second GPIO chip
(the AO bank is driven correctly because the shifting is already 0).

Protect configuration registers with a hardware spinlock.
If a hwspinlock is defined in the device-tree node used it
to be sure that none of the others processors on the SoC could
change the configuration at the same time.

The macros used to set the direction of the GPIO pins are misused,
resulting in a wrong behavior when trying to read the GPIO input level
from U-Boot.
A better macro is also used when setting the output direction.
