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

2022-12-16T17:41:49Z

The Devicetree bindings document does not have to say in the title that it is a "binding", but instead just describe the hardware. Drop trailing "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: $.*$ [bB]indings\?\.\?$/title: \1/' {} \; Signed-off-by: Krzysztof Kozlowski Acked-by: Alexandre Belloni Acked-by: Matti Vaittinen # ROHM 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 Acked-by: Viresh Kumar # cpufreq Link: https://lore.kernel.org/r/20221216163815.522628-7-krzysztof.kozlowski@linaro.org Signed-off-by: Rob Herring

dt-bindings: iio: io-channel-mux: allow duplicate channel, labels

2021-10-21T19:03:01Z

This is needed since an empty channel label is used to indicate an unused channel, and there can be more that one of those. Fixes the following problem reported by dtbs_check: envelope-detector-mux: channels: ['', '', 'sync-1', 'in', 'out', 'sync-2', 'sys-reg', 'ana-reg'] has non-unique elements arch/arm/boot/dts/at91-tse850-3.dt.yaml Suggested-by: Rob Herring Signed-off-by: Peter Rosin Acked-by: Rob Herring Signed-off-by: Jonathan Cameron

dt-bindings: iio: io-channel-mux: add optional #io-channel-cells

2021-10-21T19:03:01Z

Needed for in-kernel use of the child channels of the mux. Fixes problems like this, reported by dtbs_check: adc0mux: '#io-channel-cells' does not match any of the regexes: 'pinctrl-[0-9]+' arch/arm/boot/dts/aspeed-bmc-ampere-mtjade.dt.yaml Suggested-by: Vincent Whitchurch Signed-off-by: Peter Rosin Acked-by: Rob Herring Signed-off-by: Jonathan Cameron

dt-bindings: iio: io-channel-mux: Add property for settle time

2021-10-21T19:02:49Z

Hardware may require some time for the muxed analog signals to settle after the muxing is changed. Allow this time to be specified in the devicetree.
