But currently it doesn't look great when there is a verb in the present tense and another in the past tense. Also, the plural form should have been used for 'property'. Additionally, I don't believe that a new line between the groups of properties is necessary. > + spi-cs-setup-delay-ns = <100>; > + spi-cs-hold-delay-ns = <100>; Do you plan on deprecating the fsl, CS timing parameters tree-wide, or are you going to stop at the LS1043A-RDB?

Use SPI common propteries 'spi-cs-setup-delay-ns' and 'spi-cs-hold-delay-ns', mark private properties 'fsl,spi-cs-sck-delay' and 'fsl,spi-sck-cs-delay' as depericated.
