This series adds runtime PM support to the TI K3 UDMA DMA engine driver
and the TI SCI Interrupt Aggregator (INTA) irqchip driver on K3 SoCs.

Runtime PM callbacks are registered via SET_RUNTIME_PM_OPS and enabled
in probe via devm_pm_runtime_enable(). System sleep is handled by
delegating to pm_runtime_force_suspend/resume as late/early sleep ops,
keeping the PM runtime state machine consistent across system sleep
transitions and ensuring correct sequencing with power domain restoration
by genpd.

dma: ti: k3-udma: enable runtime PM support
irqchip: ti-sci-inta: add runtime PM and system sleep support
