Subject: [PATCH v1 2/3] sdhci-pci: enable SDIO interface on Intel Merrifield
Date: Mon, 29 Aug 2016 12:33:40 +0300 [thread overview]
Message-ID: <1472463221-11948-2-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1472463221-11948-1-git-send-email-andriy.shevchenko@linux.intel.com>
Intel Merrifield is known to have an SDIO interface and on Intel Edison board a
WiFi card is wired to it.
Enable the interface here to allow WiFi card enumeration.
