Subject: [PATCH 2/2] arm64: dts: rockchip: remove supports-cqe from rk3588 tiger
Date: Wed, 19 Feb 2025 10:33:03 +0100 [thread overview]
Message-ID: <20250219093303.2320517-2-heiko@sntech.de> (raw)
In-Reply-To: <20250219093303.2320517-1-heiko@sntech.de>

The sdhci controller supports cqe it seems and necessary code also is in
place - in theory.
At this point Jaguar and Tiger are the only boards enabling cqe support
on the rk3588 and we are seeing reliability issues under load.
This can be caused by either a controller-, hw- or driver-issue and
definitly needs more investigation to work properly it seems.
So disable cqe support on Tiger for now.
