Subject: [PATCH v3 00/13] 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].

Changes since v2:
- Added MSI support for allocating INTA interrupts
- Each patch contains respective changes.
Changes since v1:
- Consolidated both TISCI and irqchip drivers as suggested by Marc.
- Each patch contains respective changes.
