Merge branch irq/parent_device into irq/irqchip-next
* irq/parent_device: : . : Move irq_chip::parent_device to irq_domain::dev to track the : PM state of the device implementing the irqchip. : . genirq: Kill irq_chip::parent_device pinctrl: starfive: Move PM device over to irq domain pinctrl: npcm: Fix broken references to chip->parent_device gpio: tpmx86: Move PM device over to irq domain gpio: rcar: Move PM device over to irq domain gpio: omap: Move PM device over to irq domain gpio: mt7621: Kill parent_device usage irqchip/imx-intmux: Move PM device over to irq domain irqchip/renesas-irqc: Move PM device over to irq domain irqchip/renesas-intc-irqpin: Move PM device over to irq domain irqchip/gic: Move PM device over to irq domain genirq: Allow the PM device to originate from irq domain Signed-off-by: Marc Zyngier <[email protected]>
