Subject: [PATCH 2/3] arm64: dts: ti: iot2050: Disable SR2.0-only PRUs
Date: Tue,  7 Sep 2021 16:22:15 +0200	[thread overview]
Message-ID: <7855a461b66c55ef7d3281fae28040d766847deb.1631024536.git.jan.kiszka@siemens.com> (raw)
In-Reply-To: <cover.1631024536.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.
