From 0cb0b0d3c6ebb8215500685a1f70a45bbbdc8e47 Mon Sep 17 00:00:00 2001 From: Eric Miao Date: Sat, 4 Oct 2008 12:45:39 +0800 Subject: [ARM] ohci-pxa27x: introduce pxa27x_clear_otgph() Direct access to pxa27x specific register PSSR in a generic ohci driver is no good, introduce pxa27x_clear_otgph() and move the implementation into processor specific code.
