81 fsl,tuning-start-tap:
84 Specify the start delay cell point when send first CMD19 in tuning procedure.
87 fsl,tuning-step:
90 Specify the increasing delay cell steps in tuning procedure.
91 The uSDHC use one delay cell as default increasing step to do tuning process.
92 This property allows user to change the tuning step to more than one delay
94 tuning step can't find the proper delay window within limited tuning retries.
