This CL introduces how to configure PSL (Power Switch Logic) pads
properties such as input detection mode/polarity, pin-muxing and so
on via pinctrl mechanism. It includes:
1. Add two pinctrl properties and their enums for PSL input
detection configuration.
psl-in-mode:
- "level"
- "mode"
psl-in-pole:
- "low-falling"
- "high-rising"
2. Add macro functions to get PSL input detection and pin-muxing
configurations from 'pinmux', 'psl-offset' abd 'psl-polarity'
properties.
Here is an example to configure PSL_IN2 as the PSL detection input and
its mode and polarity.
/* A falling edge detection type for PSL_IN2 */
&psl_in2_gp00 {
psl-in-mode = "edge";
psl-in-pol = "low-falling";
};
A device will be introduced later which uses this pinctrl node to
configure PSL input detection settings and how to turn off VCC1 power
rail by PSL_OUT.
