From 3ea46c27eb435280fc170ed8ff8db3bf857cdf9d Mon Sep 17 00:00:00 2001 From: Joshua-Riek Date: Thu, 2 Nov 2023 23:48:50 -0400 Subject: [PATCH] arm64: dts: turing-rk1: use HS200 mode for eMMC On the production RK1 boards a new eMMC chip was selected, for some reason it causes I/O errors when writing data to the eMMC. So for now we need to use HS200 mode to avoid this issue. --- arch/arm64/boot/dts/rockchip/rk3588-turing-rk1.dtsi | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/arch/arm64/boot/dts/rockchip/rk3588-turing-rk1.dtsi b/arch/arm64/boot/dts/rockchip/rk3588-turing-rk1.dtsi index b7bba8a96d99..673535590c6c 100644 --- a/arch/arm64/boot/dts/rockchip/rk3588-turing-rk1.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3588-turing-rk1.dtsi @@ -438,15 +438,13 @@ status = "okay"; }; +/* HS400 mode cause io errors on production units */ &sdhci { bus-width = <8>; + no-mmc-hs400; no-sdio; no-sd; non-removable; - max-frequency = <200000000>; - mmc-hs400-1_8v; - mmc-hs400-enhanced-strobe; - full-pwr-cycle-in-suspend; status = "okay"; };
