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 [2] Please see the individual patches for exact changes in each patch, following are the main changes from v1: - Dropped the pruss_intc_trigger() API and patch and replaced it with a new patch achieving the same through irq_set_irqchip_state() callback (patch 5) - Added cleanup logic on INTC mapping fails and reset the mapping registers during unmap (patch 4) - Minor revisions to the bindings, no new properties introduced (patch 1) regards Suman [1] https://patchwork.kernel.org/cover/11034561/ [2] http://www.ti.com/lit/pdf/spruhz6 Andrew F.
