description:
|
|
The AST2700 features a dual-SoC architecture with two interconnected SoCs,
|
|
each having its own System Control Unit (SCU) for independent pin control.
|
|
This pin controller manages the pin multiplexing for SoC1.
|
|
|
|
The SoC1 pin controller manages pin functions including eSPI, LPC and I2C,
|
|
among others.

Pin control state.
|
|
|
|
If `function` is present, the node describes a pinmux state and must
|
|
specify `groups`.
|
|
|
|
For pin configuration, exactly one of `groups` or `pins` must be
|
|
specified in each state node. Group-level configuration applies to all
|
|
pins in the group. Pin-level configuration may be supplied in a
|
|
separate state node for individual pins; when both group-level and
|
|
pin-level configuration apply to the same pin, the pin-level
|
|
configuration takes precedence.
