From d67558b358963be5e8e39a80b3d27ba9325df72f Mon Sep 17 00:00:00 2001 From: Neal Frager <neal.frager@amd.com> Date: Tue, 4 Jun 2024 09:38:54 +0100 Subject: [PATCH] arm64: zynqmp: Enable usb3 for k24 som This patch corrects the mio and pll configuration registers for using usb3 on the kd240 starter kit. Without this patch, the usb3 to sd card bridge does not initialize correctly and u-boot is unable to find the OS located on the kd240 starter kit sd card. In addition, this patch correctly configures mio76 and mio77 as gpio pins which are used as reset gpio pins on the kd240 starter kit.
