dt-bindings: mtd: Fix nand-controller.yaml license

2023-07-15T16:05:38Z

Binding files should be dual licensed. This file was initially written as a .txt file with no specific license, so was implicitely GPLv2. Significant part of this file and its conversion into yaml were written by Bootlin employees which agree to comply with the rules regarding the dual licensing so let's fix the SPDX tag to reflect the correct license by changing it from GPL to GPL + BSD-2-Clause.

dt-bindings: mtd: Create a file for raw NAND chip properties

2023-06-22T21:04:20Z

In an effort to constrain as much as we can the existing binding, we want to add "unevaluatedProperties: false" in all the NAND chip descriptions part of NAND controller bindings. But in order to do that properly, we also need to reference a file which contains all the "allowed" properties. Right now this file is nand-chip.yaml but in practice raw NAND controllers may use additional properties in their NAND chip children node. These properties are listed under nand-controller.yaml, which makes the "unevaluatedProperties" checks fail while the description are valid. We need to move these NAND chip related properties into another file, because we do not want to pollute nand-chip.yaml which is also referenced by eg. SPI-NAND devices. Let's create a raw-nand-chip.yaml file to reference all the properties a raw NAND chip description can contain. The chain of inheritance becomes: nand-controller.yaml <- raw-nand-chip.yaml raw-nand-chip.yaml <- nand-chip.yaml spi-nand.yaml <- nand-chip.yaml Signed-off-by: Miquel Raynal Reviewed-by: Rob Herring Link: https://lore.kernel.org/linux-mtd/20230619092916.3028470-3-miquel.raynal@bootlin.com

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: mtd: physmap: Reuse the generic definitions

2022-11-17T20:59:20Z

The memory mapped MTD devices also share a lot with all the other MTD devices, so let's share the properties by referencing mtd.yaml. We can then drop mentioning the properties, to the cost of mentioning the possible "sram" node name prefix.

dt-bindings: mtd: nand-chip: Create a NAND chip description

2022-01-23T11:36:19Z

Move the NAND chip description out of the NAND controller file. Indeed, a subsequent part of the properties supported by a raw NAND chip are also supported by SPI-NAND chips. So let's create a generic NAND chip description which will be pulled by nand-controller.yaml and later by spi-nand.yaml as well.
