Subject: [PATCH 12/18] PCI: dwc: designware-ep: Do not disable BARs during initialization
Date: Fri, 18 Aug 2017 20:28:04 +0530 [thread overview]
Message-ID: <20170818145810.17649-13-kishon@ti.com> (raw)
In-Reply-To: <20170818145810.17649-1-kishon@ti.com>
Some platforms like K2G has reserved use of BAR_0 which shouldn't be
disabled by software. Avoid disabling all BARs during initialization.
