dt-bindings: mmc: Change to additionalProperties to fix fail detect Unevaluated property

2025-03-11T17:44:49Z

mmc-controller.yaml is common schema file. According to writing-schema.rst, * additionalProperties: true Rare case, used for schemas implementing common set of properties. Such schemas are supposed to be referenced by other schemas, which then use 'unevaluatedProperties: false'. Typically bus or common-part schemas. Reproduce steps: 1. Add unevaluated property 'abc' at example of fsl-imx-esdhc.yaml 2. Run make dt_binding_check DT_SCHEMA_FILES=fsl-imx-esdhc.yaml No any warning report. But suppose report below warning: mmc@70004000: Unevaluated properties are not allowed ('abc' was unexpected) Signed-off-by: Frank Li Reviewed-by: Rob Herring (Arm) Link: https://lore.kernel.org/r/20250220164655.2081224-1-Frank.Li@nxp.com Signed-off-by: Ulf Hansson

dt-bindings: mmc: controller: remove '|' when not needed

2024-12-10T14:52:26Z

Adding "|" is used to keep the description format, remove it when not needed after the split into mmc-controller.yaml and mmc-controller-common.yaml files.

dt-bindings: mmc: controller: move properties common with slot out to mmc-controller-common

2024-12-10T14:52:26Z

Move the common MMC "slot" properties because they are shared by the single-slot or multi-slot controllers, and will help defining a simple mmc-slot bindings document with proper slot properties and nodename.

dt-bindings: mmc: controller: clarify the address-cells description

2024-12-10T14:52:26Z

The term "slot ID" has nothing to do with the SDIO function number which is specified in the reg property of the subnodes, rephrase the description to be more accurate.

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.
