From 833a53c627b839a28b5925ba283109b141f6cff0 Mon Sep 17 00:00:00 2001 From: Ilya Yanok Date: Tue, 6 Nov 2012 13:48:25 +0000 Subject: musb-new: am35x backend driver Backend driver for MUSB OTG controllers found on TI AM35x. It seems that on AM35X interrupt status registers can be updated _before_ core registers. As we don't use true interrupts in U-Boot and poll interrupt status registers instead this can result in interrupt handler being called with non-updated core registers. This confuses the code and result in hanged transfers. Add a small delay in am35x_interrupt as a workaround.
