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 : - compatible : Should contain "fsl,mpc5121-psc-uart" and "fsl,mpc5121-psc" - cell-index : Index of the PSC in hardware - reg : Offset and length of the register set for the PSC device - interrupts : <a b> where a is the interrupt number of the PSC FIFO Controller and b is a field that represents an encoding of the sense and level information for the interrupt. - interrupt-parent : the phandle for the interrupt controller that services interrupts for this device. 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 ------------------------- Required properties : - compatible : Should be "fsl,mpc5121-psc-fifo" - reg : Offset and length of the register set for the PSC FIFO Controller - interrupts : <a b> where a is the interrupt number of the PSC FIFO Controller and b is a field that represents an encoding of the sense and level information for the interrupt. - interrupt-parent : the phandle for the interrupt controller that services interrupts for this device. 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 >; };
