2020-01-07ARM: dts: samsung: Rename Samsung and Exynos to lowercaseKrzysztof Kozlowski1-4/+4
Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter. The lowercase "Exynos" name is promoted by its manufacturer Samsung Electronics Co., Ltd., in advertisement materials and on website. Although advertisement materials usually use uppercase "SAMSUNG", the lowercase version is used in all legal aspects (e.g. on Wikipedia and in privacy/legal statements on https://www.samsung.com/semiconductor/privacy-global/).

Two major chunks of code are moving out of the tree and into the staging directory, uwb and wusb (wireless USB support), because there are no devices that actually use this protocol anymore, and what we have today probably doesn't work at all given that the maintainers left many many years ago. So move it to staging where it will be removed in a few releases if no one screams. Other than that, lots of little things.

2018-11-18ARM: dts: exynos: Add all CPUs in cooling mapsViresh Kumar1-3/+4
Each CPU can (and does) participate in cooling down the system but the DT only captures a handful of them, normally CPU0, in the cooling maps. Things work by chance currently as under normal circumstances its the first CPU of each cluster which is used by the operating systems to probe the cooling devices. But as soon as this CPU ordering changes and any other CPU is used to bring up the cooling device, we will start seeing failures. Also the DT is rather incomplete when we list only one CPU in the cooling maps, as the hardware doesn't have any such limitations. Update cooling maps to include all devices affected by individual trip points. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>

The cooling device properties, like "#cooling-cells" and "dynamic-power-coefficient", should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add such missing properties.

2016-12-29ARM: dts: exynos: Enable DMA support for UART modules on Exynos5 SoCsMarek Szyprowski1-0/+8
UART modules can use DMA for offloading data transfers and reducing interrupts, so enable this feature for Exynos5 boards. Tested on Google ChromeBook Snow (Exynos5250), Odroid XU (Exynos5410) and Odroid XU3 (Exynos5422) boards.

2016-11-03ARM: dts: exynos: Use human-friendly symbols for interrupt properties in exynos5Krzysztof Kozlowski1-38/+38
Replace hard-coded values of type of GIC interrupt and its flags with respective macros from header to increase code readability. Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Tested-by: Javier Martinez Canillas <javier@osg.samsung.com>
2016-11-03ARM: dts: exynos: Fix invalid GIC interrupt flags in exynos5250Krzysztof Kozlowski1-40/+40
Interrupt of type IRQ_TYPE_NONE is not allowed for GIC interrupts and generates an error: genirq: Setting trigger mode 0 for irq 16 failed (gic_set_type+0x0/0x68) The GIC requires shared interrupts to be edge rising or level high. Platform declares support for both. Arbitrarily choose level high everywhere hoping it will work on each platform.

2016-05-31ARM: dts: exynos: Move Exynos5250 and Exynos5420 nodes under socKrzysztof Kozlowski1-797/+800
The conventions is to put SoC devices under 'soc' node. In fact other our DTSes (like exynos3250.dtsi or exynos5410.dtsi) already follow it. Adjust exynos5250 and exynos5420 DTSI to follow this convention. This is also necessary for the upcoming change in exynos5410.dtsi to inherit from common exynos5.dtsi.

2016-05-31ARM: dts: exynos: Move common nodes to exynos5.dtsiKrzysztof Kozlowski1-74/+34
Exynos5420 and Exynos5250 share some nodes: the PWM, syscon (sysreg_system_controller) and first four I2C controllers. Move them to parent DTSI to avoid duplication.
