Subject: [PATCH 6/6] ACPI / LPSS: add Lynxpoint DMA controller to the list
Date: Wed, 27 Mar 2013 10:58:02 +0200 [thread overview]
Message-ID: <1364374682-8547-7-git-send-email-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <1364374682-8547-1-git-send-email-andriy.shevchenko@linux.intel.com>
In Lynxpoint we have to enable clock per each LPSS device. That's why we have
to enumerate them from drivers/acpi/acpi_lpss.c. The DMA controller is one of
such devices.
