Subject: [PATCH v2 1/1] spi: dt-bindings: convert spi-sc18is602.txt to yaml format
Convert binding doc spi-sc18is602.txt (I2C to SPI bridge) to yaml.
Additional change:
- ref spi-controller.yaml
Fix below warning:
arch/arm64/boot/dts/freescale/fsl-lx2160a-bluebox3.dtb:
/soc/i2c@...0000/i2c-mux@...i2c@...2c-mux@...i2c@...pi@28: failed to match any schema with compatible: ['nxp,sc18is602b']
Reviewed-by: Rob Herring (Arm) <robh@...nel.org>
Signed-off-by: Frank Li <Frank.Li@....com>
---
Change from v1 to v2
- fix typo SCIS603
- drop "default frequency (7372000) will be used"
- Add Rob review tag
