From bc5081617faeb3b2f0c126dc37264b87af7da47f Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Thu, 4 Feb 2016 14:18:01 +0200 Subject: usb: dwc3: drop FIFO resizing logic That FIFO resizing logic was added to support OMAP5 ES1.0 which had a bogus default FIFO size. I can't remember the exact size of default FIFO, but it was less than one bulk superspeed packet (<1024) which would prevent USB3 from ever working on OMAP5 ES1.0. However, OMAP5 ES1.0 support has been dropped by commit aa2f4b16f830 ("ARM: OMAP5: id: Remove ES1.0 support") which renders FIFO resizing unnecessary.
