[v2,0/6] Add TI PRUSS Local Interrupt Controller IRQChip driver

Message

Hi All,

The following is a v2 version of the series [1] 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 [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
