Subject[PATCHv3 0/6] Add TI PRUSS Local Interrupt Controller IRQChip driver
Hi All,

The following is a v3 version of the series [1][2] 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 [3]

Please see the individual patches for exact changes in each patch, following are
the main changes from v2:
- Convert dt-binding to YAML (patch #1).
- Address comments from Marc Zyngier regarding patch #2 and update following
patches due to those changes.
- Dropped the custom helper functions used for interrupt configuration outside
of irq driver [4]. Introduce new patch (patch 6) which uses xlate and irq
domain mapping functionality in order to map system event through 2 levels of
many-to-one mapping i.e. events to channel mapping and channels to host


Best regards
