| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | * Marvell 88PM860x Power Management IC |
| 2 | |
| 3 | Required parent device properties: |
| 4 | - compatible : "marvell,88pm860x" |
| 5 | - reg : the I2C slave address for the 88pm860x chip |
| 6 | - interrupts : IRQ line for the 88pm860x chip |
| 7 | - interrupt-controller: describes the 88pm860x as an interrupt controller (has its own domain) |
| 8 | - #interrupt-cells : should be 1. |
| 9 | - The cell is the 88pm860x local IRQ number |
| 10 | |
| 11 | Optional parent device properties: |
| 12 | - marvell,88pm860x-irq-read-clr: inicates whether interrupt status is cleared by read |
| 13 | - marvell,88pm860x-slave-addr: 88pm860x are two chips solution. <reg> stores the I2C address |
| 14 | of one chip, and this property stores the I2C address of |
| 15 | another chip. |
| 16 | |
| 17 | 88pm860x consists of a large and varied group of sub-devices: |
