H A D | musb_core.h | diff af5ec14d40e0da1de17fcca2b41c76fae5c2cb9d Tue Oct 30 13:52:25 CDT 2012 Sebastian Andrzej Siewior <bigeasy@linutronix.de> usb: musb: Perform only write access on MUSB_INTRRXE
This is part of the workaround for AM35x advisory Advisory 1.1.20. The advisory says that the IPSS bridge can't handle 8 & 16 bit read access. An 16bit read access to MUSB_INTRRXE results in an 32bit read access which also reads INTRUSB and therefore may lose interrupts. This patch uses a shadow register of MUSB_INTRRXE so we only perform write access to it.
