Subject: [PATCHv3 0/6] Add TI PRUSS Local Interrupt Controller IRQChip driver
Date:   Thu,  2 Jul 2020 16:17:53 +0200

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
   interrupts.
