Hi All,

The following is a v6 version of the series [1-5] that adds an IRQChip
driver for the local interrupt controller present within a Programmable
Real-Time Unit and Industrial Communication Subsystem (PRU-ICSS) present on a
number of TI SoCs including OMAP architecture based AM335x, AM437x, AM57xx SoCs,
Keystone 2 architecture based 66AK2G SoCs, Davinci architecture based
OMAP-L138/DA850 SoCs and the latest K3 architecture based AM65x and J721E SoCs.
Please see the v1 cover-letter [1] for details about the features of this
interrupt controller. More details can be found in any of the supported SoC
TRMs. Eg: Chapter 30.1.6 of AM5728 TRM [6]

Please see the individual patches for exact changes in each patch, following are
the main changes from v5:
- Improve patch #2 with regards to various Marc Zyngier comments.
- Drop example from commit description of patch #4.
