|
|
- reg: Base address and length of the SYSCTRL IO block.
|
|
- #clock-cells: Must be 1
|

|
Examples
|
|
--------
|
|
|
|
- SYSCTRL node:
|
|
|
|
sysctrl: system-controller@4000c000 {
|
|
compatible = "renesas,r9a06g032-sysctrl";
|
|
reg = <0x4000c000 0x1000>;
|
|
#clock-cells = <1>;
|
|
|
|
clocks = <&ext_mclk>, <&ext_rtc_clk>,
|
|
<&ext_jtag_clk>, <&ext_rgmii_ref>;
|
|
clock-names = "mclk", "rtc", "jtag", "rgmii_ref_ext";
|
|
#power-domain-cells = <0>;
|
|
};
|
|
|
|
- Other nodes can use the clocks provided by SYSCTRL as in:
|
|
|
|
#include <dt-bindings/clock/r9a06g032-sysctrl.h>
|
|
uart0: serial@40060000 {
|
|
compatible = "snps,dw-apb-uart";
|
|
reg = <0x40060000 0x400>;
|
|
interrupts = <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>;
|
|
reg-shift = <2>;
|
|
reg-io-width = <4>;
|
|
clocks = <&sysctrl R9A06G032_CLK_UART0>, <&sysctrl R9A06G032_HCLK_UART0>;
|
|
clock-names = "baudclk", "apb_pclk";
|
|
power-domains = <&sysctrl>;
|
|
};
