H A Dmpc5121-psc.txt9 Controller node fsl,mpc5121-psc-fifo is required there:
23 - fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
24 - fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)
30 for that is fsl,mpc5121-psc-spi. It requires a fsl,mpc5121-psc-fifo as well.
35 fsl,mpc512x-psc-fifo node
39 - compatible : Should be "fsl,<soc>-psc-fifo"
48 - clocks : specifies the clock needed to operate the fifo controller
