Subject: [PATCH 03/12] ARM: dts: AM33xx-l4: Update PRUSS interconnect target-module node
Date: Tue, 25 Feb 2020 14:46:40 -0600 [thread overview]
Message-ID: <20200225204649.28220-4-s-anna@ti.com> (raw)
In-Reply-To: <20200225204649.28220-1-s-anna@ti.com>
The PRU-ICSS present on some AM33xx SoCs has a very unique SYSC
register. The IP also uses a hard-reset line, and requires this
PRCM reset to be deasserted to be able to access any registers.
Update the existing PRUSS interconnect target-module with all
the required properties.
The PRUSS device itself shall be added as a child node to this
interconnect node in the future. PRU-ICSS is not supported on
AM3352 SoC though in the AM33xx family, so the target module node
should be enabled in only those derivative board files that use
a SoC containing PRU-ICSS.
