Subject: [PATCH 07/19] ARM: layerscape: drop wrong errata workaround
Date: Thu,  4 Jan 2024 15:17:34 +0100	[thread overview]
Message-ID: <20240104141746.165014-8-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20240104141746.165014-1-s.hauer@pengutronix.de>

set_usb_txvreftune() works on the USB Parameter 1 Control Register.
USB Parameter 2 Control Register has a different register layout and
calling set_usb_txvreftune() on it is wrong. Drop the bogus errata
workaround.
