Hello, A month ago, Michael was sending a new iteration of his series bringing nvmem layout support. The idea is: we currently can produce nvmem cells statically defined on top of nvmem devices (which themselves may be MTD devices sometimes) but in some cases we may need more advanced parsing, which is possible thanks to the introduction of nvmem layout parsers. I am not taking over the entire series but I recently tried to make use of these layouts for the ONIE tlv table layout and Rob (rightfully) pointed out that the description was messy, because of the mix between nvmem devices and nvmem parsers. This was known to Michael which initially argued that it was simpler to handle like that. So here is a new proposal for the bindings which is described in details within "dt-bindings: nvmem: Introduce the nvmem-layout container". The idea to avoid mixing different node contents is to use a container node when relevant (suggested by Rob) which I named nvmem-layout. This container will have a compatible that describes the parser (plus possible additional properties). Michael, I have a few fixup! patches which apply directly to your former series in order to support this additional container. I propose we first settle the bindings (including the two direct use cases as examples) and once merged, we can move forward and respin both the nvmem series + the layout drivers. # Original series (v2) from Michael Link: https://lore.kernel.org/linux-arm-kernel/20220921115813.208ff789@xps-13/T/#mb97d5376647ff3e686b9c55e3d5e0dc80879e84a Cheers, Miquèl Michael Walle (1): dt-bindings: nvmem: add YAML schema for the sl28 vpd layout Miquel Raynal (5): dt-bindings: nvmem: Fix example dt-bindings: nvmem: Introduce the nvmem-layout container dt-bindings: eeprom: Inherit from nvmem.yaml dt-bindings: vendor-prefixes: Add ONIE dt-bindings: nvmem: add YAML schema for the ONIE tlv layout .../devicetree/bindings/eeprom/at24.yaml | 5 +- .../devicetree/bindings/eeprom/at25.yaml | 1 + .../bindings/eeprom/microchip,93lc46b.yaml | 1 + .../nvmem/layouts/kontron,sl28-vpd.yaml | 60 +++++++++ .../bindings/nvmem/layouts/nvmem-layout.yaml | 34 ++++++ .../nvmem/layouts/onie,tlv-layout.yaml | 115 ++++++++++++++++++ .../devicetree/bindings/nvmem/nvmem.yaml | 8 ++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + 8 files changed, 225 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/nvmem/layouts/kontron,sl28-vpd.yaml create mode 100644 Documentation/devicetree/bindings/nvmem/layouts/nvmem-layout.yaml create mode 100644 Documentation/devicetree/bindings/nvmem/layouts/onie,tlv-layout.yaml -- 2.34.1
