Hi All, The following is a v4 version of the series [1-4] 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 [5] Please see the individual patches for exact changes in each patch, following are the main changes from v4: - Update dt-binding description (no functional changes). - Use more meaningful define/variable names, drop redundant error messages, fix error handling in case of irq == 0 (patch #2).
