2015-09-30amd/family14: Add k10temp thermal zone.Tobias Diedrich
The thermal sensor interface exposed in function 3 of the northbridge is a more convenient and faster way to access the processor-internal thermal sensor than using the SMBus/SB-TSI interface from the FCH, see the Family14 BKDG: "Tctl is a processor temperature control value used for processor thermal management. Tctl is accessible through SB-TSI and D18F3xA4[CurTmp]. Tctl is a temperature on its own scale aligned to the processors cooling requirements" Also on at least some of these boards the existing thermal zone is broken and always returns 40C (the default value if the SMBus read failed) because the SMBus muxing register (SmBus0Sel) is not set up correctly. Case in point: The fallback "smbus read failed" temperature is 40 C and the the logs taken from the board status repository for the Asrock E350M1 board all show: "ACPI: Thermal Zone [TZ00] (40 C)" e.g. http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-5054-gf584218/2013-12-20T20:56:20Z/kernel_log.txt#l390 and http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-7030-g6d7de4f/2014-10-16T15:34:19Z/kernel_console.txt#l404 and http://review.coreboot.org/gitweb?p=board-status.git;a=blob;f=asrock/e350m1/4.0-9989-gf2dfef0/2015-06-13T00:22:49Z/kernel_log.txt#l425 Example lm-sensors output with this patch on the pcengines APU1, on Linux 4.1.0-rc8+ (wiht both CONFIG_ACPI_THERMAL and CONFIG_SENSORS_K10TEMP enabled): acpitz-virtual-0 Adapter: Virtual device temp1: +54.0 C (crit = +100.0 C) k10temp-pci-00c3 Adapter: PCI adapter temp1: +54.0 C (high = +70.0 C) (crit = +100.0 C, hyst = +97.0 C) Change-Id: Id9c5b783ba424246816677099ec6651814e59f21 Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Reviewed-on: http://review.coreboot.org/10940 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Patrick Georgi <pgeorgi@google.com>

2015-06-17pcengines/apu1: Add ACPI led, button and GPIO devices.Tobias Diedrich
Provide ACPI devices with devicetree-compatible annotations for the three leds and the button of the APU1, as well as the GPIO driver. This will cause the Linux kernel to automatically load the following modules: leds_gpio (CONFIG_LEDS_GPIO) gpio_keys_polled (CONFIG_KEYBOARD_GPIO_POLLED) gpio_sb8xx (CONFIG_GPIO_SB8XX) See http://events.linuxfoundation.org/sites/events/files/slides/ACPI_vs_DT.pdf and https://lwn.net/Articles/612062/ for some more information on how the PRP0001 HID works. To make this usable a Linux GPIO driver for the AMD chipset is also required, which I am currently working on, but have not submitted upstream yet. Leds have been named after the convention in Documentation/leds/leds-class.txt: LED Device Naming ================= Is currently of the form: "devicename:colour:function" For comparison, on an OpenWRT device: GPIOs 0-21, ath79: gpio-1 (tp-link:green:usb ) out hi gpio-2 (tp-link:green:system) out lo gpio-3 (reset ) in hi gpio-5 (tp-link:green:qss ) out lo gpio-7 (qss ) in hi gpio-9 (tp-link:green:wlan ) out lo gpio-18 (rtl8366rb ) in hi gpio-19 (rtl8366rb ) in hi On the apu1: GPIOs 288-511, platform/PRP0001:00, AMD SB8XX/SB9XX/A5X/A8X GPIO driver: gpio-475 (switch1 ) in hi gpio-477 (apu1:green:led1 ) out hi gpio-478 (apu1:green:led2 ) out hi gpio-479 (apu1:green:led3 ) out hi Change-Id: I956ee92d9d98ef27a83ccb30d314543bd8634f2c Signed-off-by: Tobias Diedrich <ranma+coreboot@tdiedrich.de> Reviewed-on: http://review.coreboot.org/10540 Tested-by: build bot (Jenkins) Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Kyösti Mälkki <kyosti.malkki@gmail.com>
2015-05-21Remove address from GPLv2 headersPatrick Georgi
As per discussion with lawyers[tm], it's not a good idea to shorten the license header too much - not for legal reasons but because there are tools that look for them, and giving them a standard pattern simplifies things. However, we got confirmation that we don't have to update every file ever added to coreboot whenever the FSF gets a new lease, but can drop the address instead. util/kconfig is excluded because that's imported code that we may want to synchronize every now and then. $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, *MA[, ]*02110-1301[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 51 Franklin Street, Suite 500, Boston, MA 02110-1335, USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 59 Temple Place[-, ]*Suite 330, Boston, MA *02111-1307[, ]*USA:Foundation, Inc.:" {} + $ find * -type f -exec sed -i "s:Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.:Foundation, Inc.:" {} + $ find * -type f -a \! -name \*.patch \ -a \! -name \*_shipped \ -a \! -name LICENSE_GPL \ -a \! -name LGPL.txt \ -a \! -name COPYING \ -a \! -name DISCLAIMER \ -exec sed -i "/Foundation, Inc./ N;s:Foundation, Inc.* USA\.* *:Foundation, Inc. :;s:Foundation, Inc. $:Foundation, Inc.:" {} + Change-Id: Icc968a5a5f3a5df8d32b940f9cdb35350654bef9 Signed-off-by: Patrick Georgi <pgeorgi@chromium.org> Reviewed-on: http://review.coreboot.org/9233 Tested-by: build bot (Jenkins) Reviewed-by: Vladimir Serbinenko <phcoder@gmail.com>
