[PATCH 2/6] arm64: dts: socfpga: agilex5: enable SD UHS DDR50 on SoCDK

From: tze . yee . ng

Date: Wed Sep 23 2026 - 04:24:37 EST


From: Tze Yee Ng <tze.yee.ng@xxxxxxxxxx>

The SoCDK SD interface already advertises SDR104. Add sd-uhs-ddr50 so
the DDR50 UHS-I mode is available as well, using the DDR50 read-path
tuning defaults from the SoC dtsi.
