Subject: [PATCH] usb: dwc3: call set incr burst type func()
Date: Mon, 23 Jul 2018 14:40:57 +0800 [thread overview]
Message-ID: <1532328057-41777-1-git-send-email-pengbo.mu@nxp.com> (raw)
Calling dwc3_set_incr_burst_type() in dwc3_core_init().
This function enabled the undefined length INCR burst type and
set INCRx. Different platform may has the different burst size
type. In order to get best performance, we need to tune the burst
size to one special value, instead of the default value.
