Subject: [PATCH 2/2] arm64: dts: renesas: spider-cpu: Switch from SCIF3 to HSCIF0
Date: Mon, 13 Jun 2022 15:10:32 +0200 [thread overview]
Message-ID: <20220613131033.10053-2-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20220613131033.10053-1-wsa+renesas@sang-engineering.com>
Every loader before Linux utilizes HSCIF0 with a speed of 1843200bps.
Make Linux behave the same.
