2024-07-01spi: dt-bindings: fsl-dspi: Convert to yaml formatFrank Li1-65/+0
Convert dt-binding spi-fsl-dspi.txt to yaml format. Use part Vladimir Oltean's work at of https://lore.kernel.org/linux-spi/20221111224651.577729-1-vladimir.oltean@nxp.com/ Additional changes during convert: - compatible string "fsl,ls1028a-dspi" can be followed by fsl,ls1021a-v1.0-dspi. - Change "dspi0@4002c000" to "spi@4002c000" in example. - Reorder properties in example. - Use GIC include in example. - Deprecated fsl,spi-cs-sck-delay and fsl,spi-sck-cs-delay by use common SPI property. - Use compatible string 'jedec,spi-nor' in example. - Split peripheral part to fsl,dspi-peripheral-props.yaml. - Remove 'interrupts' and 'pinctrl' from required list. - Update 'bus-num' description. - Update 'spi-num-chipselects' description by add "cs-gpios don't count against this number". - Remove 'big-endian' description.

2020-03-05spi: spi-fsl-dspi: Make bus-num property optionalSascha Hauer1-1/+1
The SPI bus number is completely optional to Linux, so make the corresponding device tree property optional as well. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Link: https://lore.kernel.org/r/20200305115546.31814-1-s.hauer@pengutronix.de Signed-off-by: Mark Brown <broonie@kernel.org>
2020-03-04spi: spi-fsl-dspi: Add specific compatibles for all Layerscape SoCsVladimir Oltean1-6/+11
Make the second compatible string optional for LS1012A, LS1088A and LS2080A. Old versions of the spi-fsl-dspi.c driver still need to probe on the old, generic compatible string for these controllers (such as "fsl,ls1021a-v1.0-dspi") which provides less functionality. Document the device tree bindings for LS1043A and LS1046A, whose bindings are already in use in fsl-ls1043a.dtsi and fsl-ls1046a.dtsi. Introduce new compatible strings for LS1028A and LX2160A. There will be no second compatible string for these.

2017-09-05dt-bindings: Remove "status" from examplesRob Herring1-1/+0
Pretty much any node can have a status property, so it doesn't need to be in examples. Converted with the following command and removed examples with SoC and board specific splits: git grep -l -E 'status.*=.*' Documentation/devicetree/ | xargs sed -i -E '/\sstatus.*=.*"(disabled|ok|okay)/d' Acked-by: Mark Rutland <mark.rutland@arm.com> Signed-off-by: Rob Herring <robh@kernel.org>

2014-02-16spi/fsl-dspi: Convert to use regmap and add big-endian supportChao Fu1-0/+2
Freescale DSPI module will have two endianess in different platform, but ARM is little endian. So when DSPI in big endian, core in little endian, readl and writel can not adjust R/W register in this condition. This patch will remove general readl/writel, and import regmap mechanism. Data endian will be transfered in regmap APIs. Documents: dspi add bool "big-endian" in dts node if DSPI module work in big endian.
