Subject: [PATCH v2 1/2] USB: at91: fix the number of endpoint parameter
Date: Wed, 19 Feb 2014 10:07:43 +0800	[thread overview]
Message-ID: <1392775664-16404-1-git-send-email-voice.shen@atmel.com> (raw)

In sama5d3 SoC, there are 16 endpoints, which is different with
earlier SoCs (only have 7 endpoints). The USBA_NR_ENDPOINTS micro
is not suitable for sama5d3. So, get the endpoints number through
the udc->num_ep, which get from platform data for non-dt kernel,
or parse from dt node.
