* ARM: dts: exynos: Do not ignore real-world fuse values for thermal zone 0 on ↵Krzysztof Kozlowski2017-03-071-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Exynos5420 In Odroid XU3 Lite board, the temperature levels reported for thermal zone 0 were weird. In warm room: /sys/class/thermal/thermal_zone0/temp:32000 /sys/class/thermal/thermal_zone1/temp:51000 /sys/class/thermal/thermal_zone2/temp:55000 /sys/class/thermal/thermal_zone3/temp:54000 /sys/class/thermal/thermal_zone4/temp:51000 Sometimes after booting the value was even equal to ambient temperature which is highly unlikely to be a real temperature of sensor in SoC. The thermal sensor's calibration (trimming) is based on fused values. In case of the board above, the fused values are: 35, 52, 43, 58 and 43 (corresponding to each TMU device). However driver defined a minimum value for fused data as 40 and for smaller values it was using a hard-coded 55 instead. This lead to mapping data from sensor to wrong temperatures for thermal zone 0. Various vendor 3.10 trees (Hardkernel's based on Samsung LSI, Artik 10) do not impose any limits on fused values. Since we do not have any knowledge about these limits, use 0 as a minimum accepted fused value. This should essentially allow accepting any reasonable fused value thus behaving like vendor driver. The exynos5420-tmu-sensor-conf.dtsi is copied directly from existing exynos4412 with one change - the samsung,tmu_min_efuse_value.

* ARM: dts: Make CPU configuration more readable on exynos542x/5800Krzysztof Kozlowski2016-01-281-68/+4
| | | | | | | | | | | | | | | | | | | | Exynos5420 and Exynos5800 boards boot from big core (A15) but Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this is property of the board - configurable by pulling up/down gpg2-1). To make user-visible CPU ordering more consistent the 'cpus' node was overridden by exynos5422-cpus.dtsi. However this is a little bit ugly and error-prone. Overriding the CPU child nodes requires to basically reverse what was done initially in exynos5420.dtsi. Instead, split CPU configuration entirely to separate files which should be included by board DTS.

* ARM: dts: Include exynos5420-pinctrl after the nodes were defined for exynos5420Javier Martinez Canillas2015-07-211-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The dtc compiler combines all the defined nodes that have the same path so a device node definition can be in one file and later be extended in another one. That's the case of the Exynos5420 pinctrl device nodes that are defined in the exynos5420.dtsi file and extended in exynos5420-pinctrl.dtsi. But since the exynos5420.dtsi file includes the exynos5420-pinctrl.dtsi before the pinctrl device nodes are actually defined, the definition of the pinctrl device nodes happens in exynos5420-pinctrl.dtsi and are extended in exynos5420.dtsi. That is the opposite of the original intention so even when there is no difference in practice, the exynos5420-pinctrl.dtsi include should be moved at the end of the exynos5420.dtsi file after the pinctrl device nodes have been already defined. This will also allow to later change the exynos5420-pinctrl.dtsi file to use labels instead of full paths to extend the pinctrl nodes. Since keeping the include at the top, would cause a dtc build error due the pinctrl labels not being defined yet.
