2022-09-28ARM: dts: exynos: correct s5k6a3 reset polarity on Midas familyDmitry Torokhov1-1/+1
According to s5k6a3 driver code, the reset line for the chip appears to be active low. This also matches the typical polarity of reset lines in general. Let's fix it up as having correct polarity in DTS is important when the driver will be switched over to gpiod API.

2022-06-07ARM: dts: exynos: use local header for pinctrl register valuesKrzysztof Kozlowski1-1/+2
The DTS uses hardware register values directly in pin controller pin configuration. These are not some IDs or other abstraction layer but raw numbers used in the registers. These numbers were previously put in the bindings header to avoid code duplication and to provide some context meaning (name), but they do not fit the purpose of bindings. Store the constants in a header next to DTS and use them instead of bindings.

2021-03-07ARM: dts: exynos: correct PMIC interrupt trigger level on Midas familyKrzysztof Kozlowski1-1/+1
The Maxim PMIC datasheets describe the interrupt line as active low with a requirement of acknowledge from the CPU. Without specifying the interrupt type in Devicetree, kernel might apply some fixed configuration, not necessarily working for this hardware. Additionally, the interrupt line is shared so using level sensitive interrupt is here especially important to avoid races.

2020-09-02ARM: dts: exynos: Override thermal by label in MidasKrzysztof Kozlowski1-19/+15
Using full paths to extend or override a device tree node is error prone since if there was a typo error, a new node will be created instead of extending the node as it was desired. This will lead to run-time errors that could be hard to detect. A mistyped label on the other hand, will cause a dtc compile error (during build time).

Add nodes for GPU (Mali 400) to Exynos4210 and Exynos4412. Describe the GPU as much as possible however still few elements are missing: 1. Exynos4210 bus clock is not described in hardware manual therefore the IP gate clock was provided, 2. Exynos4412: Not sure what to do with CLK_G3D clock responsible for gating entire IP block (it is now being disabled as unused), 3. Regulator supplies on Trats board.

2018-11-18ARM: dts: exynos: Add all CPUs in cooling mapsViresh Kumar1-2/+6
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>
