Subject: [PATCH 05/31] usb: usbssp: Added first part of initialization sequence.
Date: Thu, 12 Jul 2018 06:47:02 +0100	[thread overview]
Message-ID: <1531374448-26532-6-git-send-email-pawell@cadence.com> (raw)
In-Reply-To: <1531374448-26532-1-git-send-email-pawell@cadence.com>

Patch adds some initialization function. The initialization sequence
is quite complicated and this patch implements it only partially.
Initialization will be completed in next few patches.

Patch introduce three new files:
1. gadget-dbg.c - file contains functions used for debugging purpose.
2. gadget-ext-caps.h - holds macro definition related to
		       Extended Capabilities
3. gadget-if - file implements stuff related to upper layer
	(e.g usb_ep_ops, usb_gadget_ops interface).
