Subject: [PATCH v2 3/4] arm64: dts: ti: k3-j7200: Add gpio nodes
Date: Tue, 17 Nov 2020 21:49:41 +0530 [thread overview]
Message-ID: <20201117161942.38754-4-nsekhar@ti.com> (raw)
In-Reply-To: <20201117161942.38754-1-nsekhar@ti.com>
From: Faiz Abbas <faiz_abbas@ti.com>
There are 4 instances of gpio modules in main domain:
gpio0, gpio2, gpio4 and gpio6
Groups are created to provide protection between different processor
virtual worlds. Each of these modules I/O pins are muxed within the
group. Exactly one module can be selected to control the corresponding
pin by selecting it in the pad mux configuration registers.
This group pins out 69 lines (5 banks). Add DT modes for each module
instance in the main domain.
Similar to the gpio groups in main domain, there is one gpio group in
wakeup domain with 2 mdoules instances in it.
The gpio group pins out 73 pins (5 banks). Add DT nodes for each module
instance in the wakeup domain.
