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

help
|
|
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.

help
|
|
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 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.

This option is an SPL-variant of the PINMUX option.
|
|
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.

This option is to enable the AT91 pinctrl driver for AT91 PIO

controller.
|
|
|
|
AT91 PIO controller is a combined gpio-controller, pin-mux and
|
|
pin-config module. Each I/O pin may be dedicated as a general-purpose
|
|
I/O or be assigned to a function of an embedded peripheral. Each I/O
|
|
pin has a glitch filter providing rejection of glitches lower than
|
|
one-half of peripheral clock cycle and a debouncing filter providing
|
|
rejection of unwanted pulses from key or push button operations. You
|
|
can also control the multi-driver capability, pull-up and pull-down
|
|
feature on each I/O pin.
