Only one - entry is expected, except for the "marvell,armadaxp-gpio" variant - for which two entries are expected: one for the general registers, - one for the per-cpu registers. Not used for marvell,armada-8k-gpio. - -- interrupts: The list of interrupts that are used for all the pins - managed by this GPIO bank. There can be more than one interrupt - (example: 1 interrupt per 8 pins on Armada XP, which means 4 - interrupts per bank of 32 GPIOs). - -- interrupt-controller: identifies the node as an interrupt controller - -- #interrupt-cells: specifies the number of cells needed to encode an - interrupt source. Should be two. - The first cell is the GPIO number. - The second cell is used to specify flags: - bits[3:0] trigger type and level flags: - 1 = low-to-high edge triggered. - 2 = high-to-low edge triggered. - 4 = active high level-sensitive. - 8 = active low level-sensitive. - -- gpio-controller: marks the device node as a gpio controller - -- ngpios: number of GPIOs this controller has - -- #gpio-cells: Should be two. The first cell is the pin number. The - second cell is reserved for flags, unused at the moment. - -Optional properties: - -In order to use the GPIO lines in PWM mode, some additional optional -properties are required. - -- compatible: Must contain "marvell,armada-370-gpio" - -- reg: an additional register set is needed, for the GPIO Blink - Counter on/off registers. - -- reg-names: Must contain an entry "pwm" corresponding to the - additional register range needed for PWM operation. - -- #pwm-cells: Should be two.
