From 156e0fd0ecf2f78b732584253a2f21c56a7e79ba Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Fri, 29 Jan 2016 16:49:47 +0200 Subject: [PATCH] serial: 8250_pci: Add Intel Broadwell ports [ Upstream commit 6c55d9b98335f7f6bd5f061866ff1633401f3a44 ] Some recent (early 2015) macbooks have Intel Broadwell where LPSS UARTs are PCI enumerated instead of ACPI. The LPSS UART block is pretty much same as used on Intel Baytrail so we can reuse the existing Baytrail setup code. Add both Broadwell LPSS UART ports to the list of supported devices.
