Subject: [PATCH v4 2/6] arm64: dts: ti: iot2050: Disable SR2.0-only PRUs
Date: Wed, 15 Sep 2021 14:27:06 +0200 [thread overview]
Message-ID: <c18b46fcf205074db2bdd6d0f7694f07216fc241.1631708830.git.jan.kiszka@siemens.com> (raw)
In-Reply-To: <cover.1631708830.git.jan.kiszka@siemens.com>
From: Jan Kiszka <jan.kiszka@siemens.com>
The IOT2050 devices described so far are using SR1.0 silicon, thus do
not have the additional PRUs of the ICSSG of the SR2.0. Disable them.
