||
|
|
|
||
|
|
When compatible with the generic version, nodes must list the
|
||
|
|
SoC-specific version corresponding to the platform first followed by the
|
||
|
|
generic version.
|
||
|
|
|
||
|
|
- reg: Base address and length of the I/O registers used by the UART.
|
||
|
|
- interrupts: Must contain an interrupt-specifier for the SCIx interrupt.
|
||
|
|
|
||
|
|
- clocks: Must contain a phandle and clock-specifier pair for each entry
|
||
|
|
in clock-names.
|
||
|
|
- clock-names: Must contain "sci_ick" for the SCIx UART interface clock.
|
||
|
|
|
||
|
|
Note: Each enabled SCIx UART should have an alias correctly numbered in the
|
||
|
|
"aliases" node.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
aliases {
|
||
|
|
serial0 = &scifa0;
|
||
|
|
};
|
||
|
|
|
||
|
|
scifa0: serial@e6c40000 {
|
||
|
|
compatible = "renesas,scifa-r8a7790", "renesas,scifa";
|
||
|
|
reg = <0 0xe6c40000 0 64>;
|
||
|
|
interrupt-parent = <&gic>;
|
||
|
|
interrupts = <0 144 IRQ_TYPE_LEVEL_HIGH>;
|
||
|
|
clocks = <&mstp2_clks R8A7790_CLK_SCIFA0>;
|
||
|
|
clock-names = "sci_ick";
|
