GPIO reset controller
=====================
A GPIO reset controller controls a single GPIO that is connected to the reset
pin of a peripheral IC. Please also refer to reset.txt in this directory for
common reset controller binding usage.
Required properties:
- compatible: Should be "gpio-reset"
- reset-gpios: A gpio used as reset line. The gpio specifier for this property
depends on the gpio controller that provides the gpio.
- #reset-cells: 0, see below
Optional properties:
- reset-delay-us: delay in microseconds. The gpio reset line will be asserted for
this duration to reset.
- reset-post-delay-ms: delay in milliseconds to wait after reset.
- initially-in-reset: boolean. If not set, the initial state should be a
deasserted reset line. If this property exists, the
reset line should be kept in reset.
example:
sii902x_reset: gpio-reset {
compatible = "gpio-reset";
reset-gpios = <&gpio5 0 GPIO_ACTIVE_LOW>;
reset-delay-us = <10000>;
initially-in-reset;
#reset-cells = <0>;
};
/* Device with nRESET pin connected to GPIO5_0 */
sii902x@39 {
/* ... */
resets = <&sii902x_reset>; /* active-low GPIO5_0, 10 ms delay */
};
