5532262d46 test: pinmux: add test for 'pinctrl-single' driver
The test adds two pinmux nodes to the device tree, one to test when a
register changes only one pin's mux (pinctrl-single,pins), and the other
to test when more than one pin's mux is changed (pinctrl-single,bits).
This required replacing the controller's register access functions when
the driver is used on sandbox.

76d470de1a pinctrl: single: add get_pin_muxing operation
It allows to display the muxing of a given pin. Inspired by more recent
versions of the Linux driver, in addition to the address and the value
of the configuration register I added the pin function retrieved from
the DT. In doing so, the information displayed does not depend on the
platform, being a generic type driver, and it can be useful for debug
purposes.

7e0a96d559 dm: gpio: Add a way to update flags
It is convenient to be able to adjust some of the flags for a GPIO while
leaving others alone. Add a function for this.

Update dm_gpio_set_dir_flags() to make use of this.

Also update dm_gpio_set_value() to use this also, since this allows the
open-drain / open-source features to be implemented directly in the
driver, rather than using the uclass workaround.

Update the sandbox tests accordingly. This involves a lot of changes to
dm_test_gpio_opendrain_opensource() since we no-longer have the direciion
being reported differently depending on the open drain/open source flags.

Also update the STM32 drivers to let the uclass handle the active low/high
logic.

Drop the GPIOD_FLAGS_OUTPUT() macro which is no-longer used.

54f5bf3d61 pinctrl: stmfx: Fix pin configuration issue
pin-controller pin's name must be equal to pin's name used in device
tree with "pins" DT property.

Issue detected on stm32mp157c-ev1 board with goodix touchscreen.
In DT, the goodix's pin is declared in DT with the node:

        goodix_pins: goodix {
		pins = "gpio14";
		bias-pull-down;
	};

Whereas in stmfx pin-controller driver, pin's name are equal to
"stmfx_gpioxx" where xx is the pin number.
This lead to not configure stmfx's pins at probe because pins is
identified by its name (see pinctrl_pin_name_to_selector() in
pinctrl-generic.c) and stmfx pin "gpio14" can't be found.

To fix this issue, come back to the original stmfx pin's name.

Revert "pinctrl: stmfx: update pin name"

This reverts commit 38d30cdcd65c73eeefac5efa328ad444a53b77dd.

cc6aa80dd1 pinctrl: renesas: Make sure the pin type is updated after setting the MUX
By default on startup all the pin types are configured to
PINMUX_TYPE_NONE (in sh_pfc_map_pins()), when pin is set as GPIO the
pin type is updated to PINMUX_TYPE_GPIO. But the type is not updated
when the pin is set as a function in sh_pfc_pinctrl_pin_set() or
sh_pfc_pinctrl_group_set() calls (these calls only set the MUX if
the pin type is PINMUX_TYPE_NONE ie unused).

So with the current implementation pin functionality could be overwritten
silently, for example if the same pin is added for SPI and serial.

This patch makes sure of updating pin type after every successful call to
sh_pfc_config_mux() and thus fixing from pin functionality to be
overwritten. Also a warning message is printed if the current pin is being
overwritten before abort.

This also avoids pin re-muxing to same type that is for example from
command line device is asked to re-probe/select (mmc dev x) we return
early with success in this case as the pin is already muxed.

bdf8fd76c0 dm: Rename U_BOOT_DRIVER_ALIAS to DM_DRIVER_ALIAS
We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but
in every other case we just use DM_. Update the alias macros to use the
DM_ prefix.

We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro
is widely used and there is at least some benefit to indicating it us a
U-Boot driver, particularly for code ported from Linux. So for now, let's

7f0f1806e3 test: pinmux: Add test for pin muxing
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.

9c08fbfc95 pinctrl: Add pinmux property support to pinctrl-generic
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.

Use the _ptr suffixed variant instead of casting. Also, convert it to

One curious part is an error check like follows in

    priv->regs = (struct wd_timer *)devfdt_get_addr(dev);
    if (!priv->regs)
            return -EINVAL;

devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error.
So, this code does not catch any error in DT parsing.

dev_read_addr_ptr() returns NULL on error, so this error check
will work.

I generated this commit by the following command:

addf358bac core: add support for U_BOOT_DRIVER_ALIAS
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,
which generates no code at all, but allows an easy way to declare driver
name aliases. Thanks to this, dtoc could be improve to look for the driver
name based on its alias when it populates the U_BOOT_DEVICE entry.

e3e2470fdd drivers: rename drivers to match compatible string
When using OF_PLATDATA, the bind process between devices and drivers
is performed trying to match compatible string with driver names.
However driver names are not strictly defined, and also there are different
names used when declaring a driver with U_BOOT_DRIVER, the name of the
symbol used in the linker list and the used in the struct driver_info.

In order to make things a bit more clear, rename the drivers names. This
will also help for further OF_PLATDATA improvements, such as checking
for valid driver names.

082faeb865 dm: Fix error handling for dev_read_addr_ptr
dev_read_addr_ptr had different semantics depending on whether OF_LIVE was
enabled. This patch converts both implementations to return NULL on error,
and converts all call sites which check for FDT_ADDR_T_NONE to check for
NULL instead. This patch also removes the call to map_physmem, since we
have dev_remap_addr* for those semantics.

commit 719cab6d2e ("dm: pinctrl: convert pinctrl-single to livetree")
converted pinctrl driver to livetree. In this conversion, the call to
read pinctrl-single,pins/bits property is provided with pinctrl device
pointer instead of pinctrl config pointer. Because of this none of the
pins gets configured. Fix it by passing the right udevice pointer.

336d4615f8 dm: core: Create a new header file for 'compat' features
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.
