interconnect patches for 5.4
Here are the interconnect driver updates for the 5.4-rc1 merge window. - New feature is the path tagging support that helps with grouping and aggregating the bandwidth requests into separate buckets based on a tag. - The first user of the path tagging is the Qualcomm sdm845 driver that now implements support for wake/sleep sets. This allows consumer drivers to express their bandwidth needs for the different CPU power states. - New interconnect driver for the qcs404 platforms and a driver that communicates bandwidth requests with remote processor over shared memory. - Cleanups and fixes.

Qualcomm QCS404 Network-On-Chip interconnect driver binding
|
||||
-----------------------------------------------------------
|
||||
|
||||
Required properties :
|
||||
- compatible : shall contain only one of the following:
|
||||
"qcom,qcs404-bimc"
|
||||
"qcom,qcs404-pcnoc"
|
||||
"qcom,qcs404-snoc"
|
||||
- #interconnect-cells : should contain 1
|
||||
|
||||
reg : specifies the physical base address and size of registers
|
||||
clocks : list of phandles and specifiers to all interconnect bus clocks
|
||||
clock-names : clock names should include both "bus" and "bus_a"
|
||||
|
||||
Example:
|
||||
|
||||
soc {
|
||||
...
|

||||
#interconnect-cells = <1>;
|
||||
clock-names = "bus", "bus_a";
|
||||
clocks = <&rpmcc RPM_SMD_BIMC_CLK>,
|
||||
<&rpmcc RPM_SMD_BIMC_A_CLK>;
|
||||
};
|
||||
|

reg = <0x00580000 0x23080>;
