[RFC uL PATCH 0/2] Add TI's event mux router driver and build

[Rahul Sharma]

This series contains the event mux router support present in TI's K3
platforms. The event mux router are of 2 types
1) gpio-mux router
2) timesync router

In normal scenarios, GPIO signals are received by CPU via GIC, but the
gpio mux router routes the incoming GPIO signal to BCDMA(Block copy
DMA) which the DMA upon receiving uses as HW triger to perform a single
block transfer or as configured.

Time sync router does the same but for the time synchronization based
events.

This driver supports both the routers but this patch series adds support
only for GPIO-mux router.
