From 1eb838d3e2a473acbb9b21278e75b79640fb2c7b Mon Sep 17 00:00:00 2001 From: Marek Szyprowski Date: Mon, 19 Jul 2010 16:01:41 +0200 Subject: [PATCH] USB: s3c-hsotg: modify only selected bits in S3C_PHYPWR register S5PV210 SoCs has 2 USB PHY interfaces, both enabled by writing zero to S3C_PHYPWR register. HS/OTG driver uses only PHY0, so do not touch bits related to PHY1.
