dt-bindings: drop redundant part of title of shared bindings

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. For shared (re-usable) schemas, name them all as "common properties".

dt-bindings: mmc: Remove comment on wakeup-source property

2022-12-07T12:29:14Z

The current comment on wakeup-source is a little confusing because the word deprecated can be interpreted at first glance to mean that wakeup-source is deprecated. Also mentioning the obsolete property confuses more than it helps. Therefore, the comment should be removed completely because the enable-sdio-wakeup property is not used in any current DTs.

dt-bindings: mmc: Set maximum documented operating frequency as 384MHz

2022-09-14T09:53:47Z

As Ulf noted in [1], the maximum operating frequency documented in the mmc-controller device-tree bindings should be updated to the maximum frequency supported by the mmc controller(s). Without this fix in place, the 'make dtbs_check' reports issues with 'max-frequency' value for ipq8074 sdhci node: arch/arm64/boot/dts/qcom/ipq8074-hk01.dtb: mmc@7824900: max-frequency:0:0: 384000000 is greater than the maximum of 200000000 [1]. https://www.spinics.net/lists/kernel/msg4442049.html Cc: Bjorn Andersson Signed-off-by: Bhupesh Sharma Reviewed-by: Rob Herring Link: https://lore.kernel.org/r/20220726084520.2895454-1-bhupesh.sharma@linaro.org Signed-off-by: Ulf Hansson

dt-bindings: mmc: Add small binding note on level shifters

2022-04-26T12:05:22Z

The VQMMC is often provided by a level shifter, so drop a small note in the bindings that this can be the case and how that is done. It is helpful information since this is pretty common.

dt-bindings: mmc: Convert MMC Card binding to a schema

2021-10-12T08:21:16Z

MMC Cards can have an optional Device Tree binding to add non-discoverable properties. Now that we have the DT validation in place, let's convert the device tree bindings for that driver over to a YAML schema. Some of these properties were already described in the MMC controller binding, even though they are not generic and do not apply to any device, so we took the occasion to fix this.

dt-bindings: mmc: Clean-up examples to match documented bindings

2021-06-14T11:57:40Z

The "sdhci" compatible is not documented though used as a fallback in a few cases. It is also not supported by a Linux driver. Just remove the example as part of ridding examples of undocumented bindings. The "brcm,bcm43xx-fmac" compatible is also not documented. Update the example to use one of the correct ones, "brcm,bcm4329-fmac", instead and use a device class based nodename.

dt-bindings: mmc: add no-mmc-hs400 flag

2021-06-14T11:57:38Z

HS400 requires a data strobe line in addition to the usual MMC signal lines. If a board design neglects to wire up this signal, HS400 mode is not available, even if both the controller and the eMMC are claiming to support this mode. Add a DT flag to allow boards to disable the HS400 support in this case.

dt-bindings: Cleanup standard unit properties

2021-01-29T22:36:06Z

Properties with standard unit suffixes already have a type and don't need type definitions. They also default to a single entry, so 'maxItems: 1' can be dropped. adi,ad5758 is an oddball which defined an enum of arrays. While a valid schema, it is simpler as a whole to only define scalar constraints. Cc: Jean Delvare Cc: Lars-Peter Clausen Cc: Dmitry Torokhov Cc: Ulf Hansson Cc: "David S.

dt-bindings: Add missing array size constraints

2021-01-11T23:42:25Z

DT properties which can have multiple entries need to specify what the entries are and define how many entries there can be. In the case of only a single entry, just 'maxItems: 1' is sufficient. Add the missing entry constraints. These were found with a modified meta-schema. Unfortunately, there are a few cases where the size constraints are not defined such as common bindings, so the meta-schema can't be part of the normal checks.
