Add a DM port of Marvell pin control driver. The A8K SoC family contains several silicone dies interconnected in a single package. Every die is normally equipped with its own pin controller unit. There are 2 pin controllers in A70x0 SoC and 3 in A80x0 SoC.

to enable some more options depending on what you want to do.

|

This provides Linux-compatible device tree interface for the pinctrl
|
|
subsystem. This feature depends on device tree configuration because
|
|
it parses a device tree to look for the pinctrl device which the
|
|
peripheral device is associated with.
|
|
|
|
If this option is disabled (it is the only possible choice for non-DT
|
|
boards), the pinctrl core provides no systematic mechanism for
|
|
identifying peripheral devices, applying needed pinctrl settings.
|
|
It is totally up to the implementation of each low-level driver.
|
|
You can save memory footprint in return for some limitations.

|
|
Say Y here if you want to use the pinctrl subsystem through the
|
|
generic DT interface. If enabled, some functions become available
|
|
to parse common properties such as "pins", "groups", "functions" and
|
|
some pin configuration parameters. It would be easier if you only
|
|
need the generic DT interface for pin muxing and pin configuration.
|
|
If you need to handle vendor-specific DT properties, you can disable
|
|
this option and implement your own set_state callback in the pinctrl
|
|
operations.

help
|
|
This option enables pin multiplexing through the generic pinctrl
|
|
framework. Most SoCs have their own own multiplexing arrangement
|
|
where a single pin can be used for several functions. An SoC pinctrl
|
|
driver allows the required function to be selected for each pin.
|
|
The driver is typically controlled by the device tree.

See the help of PINMUX for details.
|
|
The pinctrl subsystem can add a substantial overhead to the SPL
|
|
image since it typically requires quite a few tables either in the
|
|
driver or in the device tree. If this is acceptable and you need
|
|
to adjust pin multiplexing in SPL in order to boot into U-Boot,
|
|
enable this option. You will need to enable device tree in SPL
|
|
for this to work.
