Subject: [PATCH 4/6] can: rockchip-canfd: enable erratum 5 on RK3588
Date: Tue, 30 Jun 2026 18:43:34 +0200 [thread overview]
Message-ID: <20260630164336.3444550-5-heiko@sntech.de> (raw)
In-Reply-To: <20260630164336.3444550-1-heiko@sntech.de>
From: Heiko Stuebner <heiko.stuebner@cherry.de>
Lowering the clock-frequency as described in the erratum, also
leads to empty RX-fifos immediately, indicating that the
erratum is also present on the RK3588 variant.
