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 >;
