dt-bindings: drop redundant part of title (end)

2022-12-16T17:41:49Z

The Devicetree bindings document does not have to say in the title that it is a "Devicetree binding", but instead just describe the hardware. Drop trailing "Devicetree bindings" in various forms (also with trailing full stop): find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD]evice[ -]\?[tT]ree [bB]indings\?\.\?$/title: \1/' {} \; find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD]evice[ -]\?[nN]ode [bB]indings\?\.\?$/title: \1/' {} \; find Documentation/devicetree/bindings/ -type f -name '*.yaml' \ -not -name 'trivial-devices.yaml' \ -exec sed -i -e 's/^title: $.*$ [dD][tT] [bB]indings\?\.\?$/title: \1/' {} \; Signed-off-by: Krzysztof Kozlowski Acked-by: Alexandre Belloni Acked-by: Jonathan Cameron # IIO Reviewed-by: Jonathan Cameron Acked-by: Ulf Hansson # MMC Acked-by: Stephen Boyd # clk Acked-by: Dmitry Torokhov # input Acked-by: Mark Brown Acked-by: Hans Verkuil # media Acked-by: Sebastian Reichel # power Link: https://lore.kernel.org/r/20221216163815.522628-5-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring

dt-bindings: arm: sunxi: Add several MBUS compatibles

2022-07-08T16:49:24Z

All of the sunxi SoCs since at least the A33 have a similar structure for the MBUS and DRAM controller, but they all have minor differences in MBUS port assignments and DRAM controller behavior. Give each SoC its own compatible. Signed-off-by: Samuel Holland Acked-by: Rob Herring Signed-off-by: Jernej Skrabec Link: https://lore.kernel.org/r/20220702042447.26734-2-samuel@sholland.org

dt-bindings: arm: sunxi: Default to the full MBUS binding

2022-07-08T16:48:24Z

Some older SoCs use a deprecated MBUS binding with some clocks missing. Currently, new SoCs must opt in to the complete binding. This should be the default, so new SoCs do not accidentally use the deprecated version.

dt-bindings: arm: sunxi: Add H5 MBUS compatible

2021-11-23T10:29:49Z

The H5 SoC has a MBUS very similar to the H3 SoC, but it has a smaller MDFS divider range (1-4 instead of 1-16). Add a separate compatible for this variant.

dt-bindings: arm: sunxi: Expand MBUS binding

2021-11-23T10:29:44Z

The MBUS provides more than address translation and bandwidth control. It also provides a PMU to measure bandwidth usage by certain masters, and it provides notification via IRQ when they are active or idle. The MBUS is also tightly integrated with the DRAM controller to provide a Memory Dynamic Frequency Scaling (MDFS) feature. In view of this, the MBUS binding needs to represent the hardware resources needed for MDFS, which include the clocks and MMIO range of the adjacent DRAM controller. Add the additional resources for the H3 and A64 compatibles, and a new example showing how they are used.

dt-bindings: sunxi: Add Allwinner A80 PRCM Binding

Even though we've used the A80 PRCM driver for some time and a number of boards using it already, we never had a binding for it. Let's add it based on what the driver expects and the boards are providing.
