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 interrupts.
