MPC5121 PSC Device Tree Bindings

PSC in UART mode

For PSC in UART mode the needed PSC serial devices
are specified by fsl,mpc5121-psc-uart nodes in the
fsl,mpc5121-immr SoC node. Additionally the PSC FIFO
Controller node fsl,mpc5121-psc-fifo is requered there:

fsl,mpc5121-psc-uart nodes

Required properties :

Recommended properties :

  • fsl,rx-fifo-size : the size of the RX fifo slice (a multiple of 4)
  • fsl,tx-fifo-size : the size of the TX fifo slice (a multiple of 4)

fsl,mpc5121-psc-fifo node

Example for a board using PSC0 and PSC1 devices in serial mode:

serial@11000 {
compatible = “fsl,mpc5121-psc-uart”, “fsl,mpc5121-psc”;
cell-index = <0>;
reg = <0x11000 0x100>;
interrupts = <40 0x8>;
interrupt-parent = < &ipic >;
fsl,rx-fifo-size = <16>;
fsl,tx-fifo-size = <16>;
};

serial@11100 {
compatible = “fsl,mpc5121-psc-uart”, “fsl,mpc5121-psc”;
cell-index = <1>;
reg = <0x11100 0x100>;
interrupts = <40 0x8>;
interrupt-parent = < &ipic >;
fsl,rx-fifo-size = <16>;
fsl,tx-fifo-size = <16>;
};

pscfifo@11f00 {
compatible = “fsl,mpc5121-psc-fifo”;
reg = <0x11f00 0x100>;
interrupts = <40 0x8>;
interrupt-parent = < &ipic >;
};
