From 089c729ae440c6df35eeac7998525718fcee0323 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Wed, 19 Feb 2014 16:10:29 +0200 Subject: [PATCH] i2c: designware-pci: Add Baytrail PCI IDs Intel Baytrail I2C controllers can be enumerated from PCI as well as from ACPI. In order to support this add the Baytrail PCI IDs to the driver.
