From 0abe3863d05f3175866cfaea50f66dc3ee043220 Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Sun, 20 Sep 2020 02:18:50 +0200 Subject: [PATCH] usb: dwc2: add support for APM82181 USB OTG adds the specific compatible string for the DWC2 IP found in the APM82181 SoCs. The IP is setup correctly through the auto detection... With the exception of the AHB Burst Size. The default of GAHBCFG_HBSTLEN_INCR4 of the "snps,dwc2" can cause a system hang when the USB and SATA is used concurrently. Because the predecessor (PPC460EX (Canyonlands)) already had the same problem, this SoC can make use of the existing dwc2_set_amcc_params() function.
