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
