required if you need to use the optional input-debounce property. Any new
device tree should set them.
Each pin bank, depending on the SoC, can have an associated regulator:
- vcc-pa-supply: for the A10, A20, A31, A31s, A80 and R40 SoCs
- vcc-pb-supply: for the A31, A31s, A80 and V3s SoCs
- vcc-pc-supply: for the A10, A20, A31, A31s, A64, A80, H5, R40 and V3s SoCs
- vcc-pd-supply: for the A23, A31, A31s, A64, A80, A83t, H3, H5 and R40 SoCs
- vcc-pe-supply: for the A10, A20, A31, A31s, A64, A80, R40 and V3s SoCs
- vcc-pf-supply: for the A10, A20, A31, A31s, A80, R40 and V3s SoCs
- vcc-pg-supply: for the A10, A20, A31, A31s, A64, A80, H3, H5, R40 and V3s SoCs
- vcc-ph-supply: for the A31, A31s and A80 SoCs
- vcc-pl-supply: for the r-pinctrl of the A64, A80 and A83t SoCs
- vcc-pm-supply: for the r-pinctrl of the A31, A31s and A80 SoCs
Optional properties:
- input-debounce: Array of debouncing periods in microseconds. One period per
irq bank found in the controller. 0 if no setup required.
