differ between different families. May be
'virtex2p', 'virtex4', or 'virtex5'.
+ vi) Xilinx Uart 16550
+
+ Xilinx UART 16550 devices are very similar to the NS16550 but with
+ different register spacing and an offset from the base address.
+
+ Requred properties:
+ - clock-frequency : Frequency of the clock input
+ - reg-offset : A value of 3 is required
+ - reg-shift : A value of 2 is required
+
+
p) Freescale Synchronous Serial Interface
The SSI is a serial device that communicates with audio codecs. It can
big-endian;
};
+ r) Freescale Display Interface Unit
+
+ The Freescale DIU is a LCD controller, with proper hardware, it can also
+ drive DVI monitors.
+
+ Required properties:
+ - compatible : should be "fsl-diu".
+ - reg : should contain at least address and length of the DIU register
+ set.
+ - Interrupts : one DIU interrupt should be describe here.
+
+ Example (MPC8610HPCD)
+ display@2c000 {
+ compatible = "fsl,diu";
+ reg = <0x2c000 100>;
+ interrupts = <72 2>;
+ interrupt-parent = <&mpic>;
+ };
+
+ s) Freescale on board FPGA
+
+ This is the memory-mapped registers for on board FPGA.
+
+ Required properities:
+ - compatible : should be "fsl,fpga-pixis".
+ - reg : should contain the address and the lenght of the FPPGA register
+ set.
+
+ Example (MPC8610HPCD)
+ board-control@e8000000 {
+ compatible = "fsl,fpga-pixis";
+ reg = <0xe8000000 32>;
+ };
+
+ t) Freescale MSI interrupt controller
+
+ Reguired properities:
+ - compatible : compatible list, contains 2 entries,
+ first is "fsl,CHIP-msi", where CHIP is the processor(mpc8610, mpc8572,
+ etc.) and the second is "fsl,mpic-msi" or "fsl,ipic-msi" depending on
+ the parent type.
+ - reg : should contain the address and the length of the shared message
+ interrupt register set.
+ - msi-available-ranges: use <start count> style section to define which
+ msi interrupt can be used in the 256 msi interrupts. This property is
+ optional, without this, all the 256 MSI interrupts can be used.
+ - interrupts : each one of the interrupts here is one entry per 32 MSIs,
+ and routed to the host interrupt controller. the interrupts should
+ be set as edge sensitive.
+ - interrupt-parent: the phandle for the interrupt controller
+ that services interrupts for this device. for 83xx cpu, the interrupts
+ are routed to IPIC, and for 85xx/86xx cpu the interrupts are routed
+ to MPIC.
+
+ Example
+ msi@41600 {
+ compatible = "fsl,mpc8610-msi", "fsl,mpic-msi";
+ reg = <0x41600 0x80>;
+ msi-available-ranges = <0 0x100>;
+ interrupts = <
+ 0xe0 0
+ 0xe1 0
+ 0xe2 0
+ 0xe3 0
+ 0xe4 0
+ 0xe5 0
+ 0xe6 0
+ 0xe7 0>;
+ interrupt-parent = <&mpic>;
+ };
+
+ u) Freescale General-purpose Timers Module
+
+ Required properties:
+ - compatible : should be
+ "fsl,<chip>-gtm", "fsl,gtm" for SOC GTMs
+ "fsl,<chip>-qe-gtm", "fsl,qe-gtm", "fsl,gtm" for QE GTMs
+ "fsl,<chip>-cpm2-gtm", "fsl,cpm2-gtm", "fsl,gtm" for CPM2 GTMs
+ - reg : should contain gtm registers location and length (0x40).
+ - interrupts : should contain four interrupts.
+ - interrupt-parent : interrupt source phandle.
+ - clock-frequency : specifies the frequency driving the timer.
+
+ Example:
+
+ timer@500 {
+ compatible = "fsl,mpc8360-gtm", "fsl,gtm";
+ reg = <0x500 0x40>;
+ interrupts = <90 8 78 8 84 8 72 8>;
+ interrupt-parent = <&ipic>;
+ /* filled by u-boot */
+ clock-frequency = <0>;
+ };
+
+ timer@440 {
+ compatible = "fsl,mpc8360-qe-gtm", "fsl,qe-gtm", "fsl,gtm";
+ reg = <0x440 0x40>;
+ interrupts = <12 13 14 15>;
+ interrupt-parent = <&qeic>;
+ /* filled by u-boot */
+ clock-frequency = <0>;
+ };
