This patchset adds a simple latching_switch, which is a switch that can be turned on/off by a trigger.
The latching switch is a switch that can be turned on and off. When the input new state and match the trigger edge, the switch state will be toggled. This device privide 2 properties `state(bool)` and `trigger-edge(string)`, and 2 gpios `input` and `output`. The `state` property is the initial state of the switch, and the `trigger-edge` property is the edge that will trigger the switch state to be toggled, the value can be `rising`, `falling` or `both`. V2: - Rename `host-power` to `latching-switch` - Add `trigger-edge` property - Add `state` property - Using anonymous gpio - Rename power button to input, and power good to output - Reorder the patchset - Rebase to latest master Jian Zhang (3): hw/misc/latching_switch: Add a simple latching_switch device hw/gpio/aspeed_gpio: Add gpios in/out init hw/arm/aspeed: g220a: Add a latching switch device MAINTAINERS | 2 + hw/arm/Kconfig | 1 + hw/arm/aspeed.c | 20 +++ hw/gpio/aspeed_gpio.c | 17 +++ hw/misc/Kconfig | 3 + hw/misc/latching_switch.c | 212 ++++++++++++++++++++++++++++++ hw/misc/meson.build | 1 + include/hw/misc/latching_switch.h | 56 ++++++++ 8 files changed, 312 insertions(+) create mode 100644 hw/misc/latching_switch.c create mode 100644 include/hw/misc/latching_switch.h -- 2.25.1
