MediaTek DVFSRC
|
||
|
|
|
||
|
|
The Dynamic Voltage and Frequency Scaling Resource Collector (DVFSRC) is a
|
||
|
|
HW module which is used to collect all the requests from both software and
|
||
|
|
hardware and turn into the decision of minimum operating voltage and minimum
|
||
|
|
DRAM frequency to fulfill those requests.
|
||
|
|
|
||
|
|
Required Properties:
|
||
|
|
- compatible: Should be one of the following
|
||
|
|
- "mediatek,mt8183-dvfsrc": For MT8183 SoC
|
||
|
|
- "mediatek,mt6779-dvfsrc": For MT6779 SoC
|
||
|
|
- reg: Address range of the DVFSRC unit
|
||
|
|
- clock-names: Must include the following entries:
|
||
|
|
"dvfsrc": DVFSRC module clock
|
||
|
|
- clocks: Must contain an entry for each entry in clock-names.
|
||
|
|
- #interconnect-cells : should contain 1
|
||
|
|
- interconnect : interconnect providers support dram bandwidth requirements.
|
||
|
|
The provider is able to communicate with the DVFSRC and send the dram
|
||
|
|
bandwidth to it. shall contain only one of the following:
|
||
|
|
"mediatek,dvfsrc-mt8183-emi"
|
||
|
|
"mediatek,dvfsrc-mt6779-emi"
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
dvfsrc@10012000 {
|
||
|
|
compatible = "mediatek,mt8183-dvfsrc";
|
||
|
|
reg = <0 0x10012000 0 0x1000>;
|
||
|
|
clocks = <&infracfg CLK_INFRA_DVFSRC>;
|
||
|
|
clock-names = "dvfsrc";
|
||
|
|
ddr_emi: interconnect {
|
||
|
|
compatible = "mediatek,mt8183-emi";
|
||
|
|
#interconnect-cells = <1>;
|
||
|
|
};
|

|
|
};
