From 1318ea600b348cff43a66ffa6296a552b59e8888 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Sat, 3 Jun 2017 03:52:57 -0500 Subject: superio/ite/it8720f: add new IT8720F Super I/O This device is extremely similar to the IT8718F, so support is based on existing support for the IT8718F. The CIR device is only detected by Linux/Windows from the ACPI tables, so ACPI support is extended from the IT8783E/F (for ACPI). This Super I/O is used on the Foxconn G41S-K. Tested, working: * Serial port 1 * Environment controller - Temperature monitoring - Voltage monitoring - Fan control (automatic and manual) * PS/2 keyboard and mouse Appears, OS driver loads, but otherwise untested: * Serial port 2 * Consumer IR Untested: * Floppy controller * Parallel port * GPIO Change-Id: Ib9a6fe91a772d78f4d122a6c516feff8658ada0a Signed-off-by: Samuel Holland Reviewed-on: https://review.coreboot.org/20026 Tested-by: build bot (Jenkins) Reviewed-by: Arthur Heymans Reviewed-by: Felix Held --- src/superio/ite/it8720f/superio.c | 101 ++++++++++++++++++++++++++++++++++++++ 1 file changed, 101 insertions(+) create mode 100644 src/superio/ite/it8720f/superio.c (limited to 'src/superio/ite/it8720f/superio.c') diff --git a/src/superio/ite/it8720f/superio.c b/src/superio/ite/it8720f/superio.c new file mode 100644 index 0000000000..74ffefa44c --- /dev/null +++ b/src/superio/ite/it8720f/superio.c @@ -0,0 +1,101 @@ +/* + * This file is part of the coreboot project. + * + * Copyright (C) 2016 secunet Security Networks AG + * Copyright (C) 2017 Samuel Holland + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + * This program is distributed in the hope that it will be useful, + * but WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
