From 6462cbd54d2fa649b27633267d8ddf835705e47a Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Sun, 30 Jun 2013 14:19:33 +0300 Subject: [PATCH] usb: dwc3: let non-DT platforms pass tx-fifo-resize flag; in case we're not in a DT boot, we should still be able to tell the driver how to behave. In order to be able to pass flags to the driver, we introduce platform_data structure which the core driver should use.
