Subject: [PATCH v2 00/10] Add support for TISCI irqchip drivers

TISCI abstracts the handling of IRQ routes where interrupt sources
are not directly connected to host interrupt controller. This series
adds support for:
- TISCI commands needed for IRQ configuration
- Interrupt Router(INTR) and Interrupt Aggregator(INTA) drivers

More information on TISCI IRQ management can be found here[1].
Complete TISCI resource management information can be found here[2].
AM65x SoC related TISCI information can be found here[3].
INTR and INTA related information can be found in TRM[4].
