Detailed Description

Helper layer that provides the common functionality of PPI system.

This is the only place where PPI system resources are managed.

There are 4 types of peripheral interconnection systems:

PPI - nRF51, nRF52 - Simple one-to-one with fork (one-to-two) feature added in nRF52.
DPPI - nRF53, nRF91 - Distributed PPI allowing many-to-many connections.
D2PPI - nRF54L, nRF71 - Distributed DPPI, multiple instances of DPPI in each domain. Domains connected through PPIB.
SD2PPI - nRF54H - Secure D2PPI. Similar to nRF54L solution but only secure core can configure PPIB directions and DPPI channel ownership. PPIB connects buses in the same domain and domains are conencted using IPCT. However cross-domain connection can be seen as set of 2 connections DomainAEndpoint-to-IPCT and DomainBEndpoint-to-IPCT.

		nrfx_gppi_group_handle_t *	p_handle )
