From 8d8a0435d10225499ddc8ad36446773ddecaf484 Mon Sep 17 00:00:00 2001 From: Yoshihiro Shimoda Date: Wed, 6 Dec 2017 17:18:32 +0900 Subject: usb: renesas_usbhs: add usbhs_pipe_clear_without_sequence() function This patch adds usbhs_pipe_clear_without_sequence() function. The controller has the pipe buffer and the PIPEnCTR.ACLRM can clear it completely. But, it's also clear the data sequence. So, the driver needs to get the sequence before.
