From 163f8858ae8bfcd94ef8d6c4ed75ff3abb642450 Mon Sep 17 00:00:00 2001 From: Alexey Brodkin Date: Wed, 31 Jan 2018 17:56:59 +0300 Subject: [PATCH] usb: dwc2: Rename CONFIG_DWC2_UTMI_PHY_WIDTH to CONFIG_DWC2_UTMI_WIDTH For some reason from day one we used to have both CONFIG_DWC2_UTMI_WIDTH mentioned in dwc2.h and in scripts/config_whitelist.txt but never really used and CONFIG_DWC2_UTMI_PHY_WIDTH used in real code in dwc2.c (but never defined). Moreover even though CONFIG_DWC2_UTMI_WIDTH might be either 8 or 16 depending on hardware (and the same is said in a comment for it in dwc2.h) but then 8 is hardcoded in the header leaving no ability to override this value in board's configuration.
