From 0f554e37dad416f445cd3ec5935f5aec1b0e7ba5 Mon Sep 17 00:00:00 2001 From: Frank Li Frank.Li@nxp.com Date: Mon, 15 May 2023 12:20:53 -0400 Subject: [PATCH] arm64: dts: imx8: fix USB 3.0 Gadget Failure in QM & QXPB0 at super speed
Resolve USB 3.0 gadget failure for QM and QXPB0 in super speed mode with single IN and OUT endpoints, like mass storage devices, due to incorrect ACTUAL_MEM_SIZE in ep_cap2 (32k instead of actual 18k). Implement dt property cdns,on-chip-buff-size to override ep_cap2 and set it to 18k for imx8QM and imx8QXP chips. No adverse effects for 8QXP C0.
