Subject: [PATCH v5 4/4] arm64: dts: rockchip: Enable CAN controller on RK3588-Tiger-Haikou
Date: Sat, 25 Jul 2026 15:03:34 +0800 [thread overview]
Message-ID: <tencent_8E35228F9F4F133FCDBCCC4902F6887D0006@qq.com> (raw)
In-Reply-To: <20260725-master-v5-0-75da459d2b93@qq.com>
From: Heiko Stuebner <heiko.stuebner@cherry.de>
CAN0 is piped through the Q7-connector to the CAN-Header on the Haikou
base-board, so enable support for it there.
At least on RK3588-Tiger, the CAN clocks default to 99MHz, limiting
usable CAN bitrates without skew. Errata documentation mentions
300MHz as the default frequency on RK3568, so replicate this here
to allow more bitrates.
