264cbb1871 scmi: pinctrl: add pinctrl message IDs
Add all the pinctrl message IDs.  I renamed SCMI_MSG_PINCTRL_CONFIG_SET
to SCMI_PINCTRL_SETTINGS_CONFIGURE so the naming matches the spec better.

The i.MX9 pinctrl match table currently lists all SoC compatibles
unconditionally, which may lead to unused entries being included when
building for specific SoC variants. Guard each compatible entry with
the corresponding CONFIG_IMX9[X] option so only the required SoC

9c74ce7846 pinctrl: nxp: imx93: Rename to imx9
We are going to add pinctrl data support for both i.MX93 and i.MX91.
Since these SoCs share the same pinctrl driver structure, rename
pinctrl-imx93.c to a more generic pinctrl-imx9.c and update all related
variable and function names accordingly.

This prepares the driver for supporting additional i.MX9 family SoCs.

612421af51 arm: pinctrl: Define .mux_mask field for NXP's SoC
The commit e8a9521e64
("vf500/vf610: synchronise device trees with linux")
has synchronized U-Boot's DTS with v5.19 Linux kernel.
It turned out that in Linux's upstream iomuxc node description the
'fsl,mux_mask' was missing, so the U-Boot's pinctrl driver for NXP's
Vybrid SoC was not working properly.

As by default the mux mask was set to 0, for example the vf610 based
boards (like BK4) were bricked, due to misconfiguration of gpio at
early boot stage.

The fix for all NXP eligible boards is to define .mux_mask field for
soc specific *pinctrl_soc_info structure and use it directly in pinctrl
MMIO driver, without the need to read the "fsl,mux_mask" property from
device tree.

This change brings the NXP's pinctrl driver in U-Boot closer to Linux
upstream one.

40c477c71c pinctrl: imx: Split imx_pinctrl_set_state() into common and mmio parts
Split imx_pinctrl_set_state() into imx_pinctrl_set_state_common() and
imx_pinctrl_set_state_mmio(). The former does the common configuration
parsing, the later does call imx_pinctrl_set_state_common() and then
does pin configuration using either SCU or MMIO accesses. The SCU part
is going to be moved out in follow up patches.

This is a preparatory patch for follow up pinctrl drivers which
do not use the MMIO accessors, but some other means, like SCU or
otherwise. Those will call the common imx_pinctrl_set_state_common()
function wrapped into some other imx_pinctrl_set_state_*() function,
in a way similar to imx_pinctrl_set_state_mmio() does so for MMIO
accesses.

Update all imx_pinctrl_set_state_mmio() call sites to call
imx_pinctrl_set_state_mmio() instead.

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.

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

In order to make things a bit more clear, rename the drivers names. This
