dt-bindings: mtd: jedec,spi-nor: Document CPOL/CPHA support

2023-03-22T15:59:08Z

SPI EEPROMs typically support both SPI Mode 0 (CPOL=CPHA=0) and Mode 3 (CPOL=CPHA=1). However, using the latter is currently flagged as an error by "make dtbs_check", e.g.: arch/arm/boot/dts/r8a7791-koelsch.dtb: flash@0: Unevaluated properties are not allowed ('spi-cpha', 'spi-cpol' were unexpected) From schema: Documentation/devicetree/bindings/mtd/jedec,spi-nor.yaml Fix this by documenting support for CPOL=CPHA=1.

dt-bindings: reference MC peripheral properties in relevant devices

2023-02-07T21:47:27Z

Several devices can be attached to memory controllers (or memory-mapped buses), thus they can come with additional controller-specific properties, e.g. devices wired under Intel IXP4XX bus: cfi-flash, intel,ixp4xx-compact-flash, NS8250 serial and MAX6369 watchdog. Referencing Memory Controller or IXP4XX bus peripheral properties fixes few dtbs_check warnings like: intel-ixp42x-gateworks-gw2348.dtb: ide@1,0: Unevaluated properties are not allowed ('intel,ixp4xx-eb-ahb-split-transfers', 'intel,ixp4xx-eb-byte-access', ...

dt-bindings: mtd: partitions: Fix partition node name pattern

2023-01-30T16:03:46Z

The 'partition' node name pattern is missing start and end anchors, so anything is allowed before or after the regex pattern. There's no in tree users needing that, so add anchors to the pattern.
