Subject: [PATCH] arm64: dts: rockchip: fix eMMC corruption on NanoPC-T6 with A3A444 chips
Date: Fri, 17 Oct 2025 15:39:54 +0800 [thread overview]
Message-ID: <20251017073954.130710-1-cnsztl@gmail.com> (raw)
From: Grzegorz Sterniczuk <grzegorz@sternicz.uk>
Some NanoPC-T6 boards with A3A444 eMMC chips experience I/O errors and
