[PATCH 0/2] Add runtime PM support to K3 UDMA and K3 INTA
Posted by Rahul Sharma 1 month, 2 weeks ago
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

Hi,

This patch series consists of 2 different subsystems of Linux. But
they work together in same subsystem of SoC that is K3 DMSS(Data Movement
Subsystem).

Both patches can be merged to their respective trees, with no
inter-dependency. They have been posted together for the ease of review.

BR,
Rahul
