Subject: [PATCHv2 20/26] nsp32: drop bus reset
Date: Fri, 25 Aug 2017 13:57:15 +0200	[thread overview]
Message-ID: <1503662241-127788-21-git-send-email-hare@suse.de> (raw)
In-Reply-To: <1503662241-127788-1-git-send-email-hare@suse.de>

From: Hannes Reinecke <hare@suse.com>

bus reset is a host reset without nsp32hw_init(), and will always
return SUCCESS, thus disabling the use of host reset.
So drop bus reset in favour of host reset.
