* Nuvoton NPCM7XX Clock Controller
|
||||
|
||||
Nuvoton Poleg BMC NPCM7XX contains an integrated clock controller, which
|
||||
generates and supplies clocks to all modules within the BMC.
|
||||
|
||||
External clocks:
|
||||
|
||||
There are six fixed clocks that are generated outside the BMC. All clocks are of
|
||||
a known fixed value that cannot be changed. clk_refclk, clk_mcbypck and
|
||||
clk_sysbypck are inputs to the clock controller.
|
||||
clk_rg1refck, clk_rg2refck and clk_xin are external clocks suppling the
|
||||
network. They are set on the device tree, but not used by the clock module. The
|
||||
network devices use them directly.
|
||||
Example can be found below.
|
||||
|
||||
All available clocks are defined as preprocessor macros in:
|
||||
dt-bindings/clock/nuvoton,npcm7xx-clock.h
|
||||
and can be reused as DT sources.
|
||||
|
||||
Required Properties of clock controller:
|
||||
|
||||
- compatible: "nuvoton,npcm750-clk" : for clock controller of Nuvoton
|
||||
Poleg BMC NPCM750
|
||||
|
||||
- reg: physical base address of the clock controller and length of
|
||||
memory mapped region.
|
||||
|
||||
- #clock-cells: should be 1.
|
||||
|
||||
Example: Clock controller node:
|
||||
|
||||
clk: clock-controller@f0801000 {
|
||||
compatible = "nuvoton,npcm750-clk";
|
||||
#clock-cells = <1>;
|
||||
reg = <0xf0801000 0x1000>;
|
||||
clock-names = "refclk", "sysbypck", "mcbypck";
|
||||
clocks = <&clk_refclk>, <&clk_sysbypck>, <&clk_mcbypck>;
|
||||
};
|
||||
|
||||
Example: Required external clocks for network:
|
||||
|
||||
/* external reference clock */
|
||||
clk_refclk: clk-refclk {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <25000000>;
|
||||
clock-output-names = "refclk";
|
||||
};
|
||||
|
||||
/* external reference clock for cpu. float in normal operation */
|
||||
clk_sysbypck: clk-sysbypck {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <800000000>;
|
||||
clock-output-names = "sysbypck";
|
||||
};
|
||||
|
||||
/* external reference clock for MC. float in normal operation */
|
||||
clk_mcbypck: clk-mcbypck {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <800000000>;
|
||||
clock-output-names = "mcbypck";
|
||||
};
|
||||
|
||||
/* external clock signal rg1refck, supplied by the phy */
|
||||
clk_rg1refck: clk-rg1refck {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <125000000>;
|
||||
clock-output-names = "clk_rg1refck";
|
||||
};
|
||||
|
||||
/* external clock signal rg2refck, supplied by the phy */
|
||||
clk_rg2refck: clk-rg2refck {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <125000000>;
|
||||
clock-output-names = "clk_rg2refck";
|
||||
};
|
||||
|
||||
clk_xin: clk-xin {
|
||||
compatible = "fixed-clock";
|
||||
#clock-cells = <0>;
|
||||
clock-frequency = <50000000>;
|
||||
clock-output-names = "clk_xin";
|
||||
};
|
||||
|
||||
|
||||
Example: GMAC controller node that consumes two clocks: a generated clk by the
|
||||
clock controller and a fixed clock from DT (clk_rg1refck).
|
||||
|
||||
ethernet0: ethernet@f0802000 {
|
||||
compatible = "snps,dwmac";
|
||||
reg = <0xf0802000 0x2000>;
|
||||
interrupts = <0 14 4>;
|
||||
interrupt-names = "macirq";
|
||||
clocks = <&clk_rg1refck>, <&clk NPCM7XX_CLK_AHB>;
|
||||
clock-names = "stmmaceth", "clk_gmac";
|
||||
};

Qualcomm Technologies, Inc. RPMh Clocks
|
||||
-------------------------------------------------------
|
||||
|
||||
Resource Power Manager Hardened (RPMh) manages shared resources on
|
||||
some Qualcomm Technologies Inc. SoCs. It accepts clock requests from
|
||||
other hardware subsystems via RSC to control clocks.
|
||||
|
||||
Required properties :
|
||||
- compatible : shall contain "qcom,sdm845-rpmh-clk"
|
||||
|
||||
- #clock-cells : must contain 1
|
||||
|
||||
Example :
|
||||
|
||||
#include <dt-bindings/clock/qcom,rpmh.h>
|
||||
|
||||
&apps_rsc {
|
||||
rpmhcc: clock-controller {
|

compatible = "qcom,sdm845-rpmh-clk";
|
||||
#clock-cells = <1>;
