From 7fd097e727466cda1b22beca6cb11096b8be88d2 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 10 Oct 2011 22:00:42 -0700 Subject: usb: gadget: renesas_usbhs: each pipe hold maxpacket size Current renesas_usbhs pipe accessed DCPMAXP/PIPEMAXP register to get own maxpacket size every time. But maxpacket size isn't changed after pipe start, and register access is too slow. This patch adds new maxp variable to keep own maxpacket. And un-used function are removed.
