Subject: [PATCH v4 1/5] dt-bindings: interconnect: Add Qualcomm QCS404 DT bindings
The Qualcomm QCS404 platform has several buses that could be controlled
and tuned according to the bandwidth demand.
Reviewed-by: Bjorn Andersson <bjorn.andersson@...aro.org>
Signed-off-by: Georgi Djakov <georgi.djakov@...aro.org>
---
v4:
- Add the DT header into this patch.
- Pick Bjorn's r-b.
v3:
- Add a reg property and move the interconnect nodes under the "soc" node.
v2:
- No changes.

+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
+
+Optional properties :
+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_clk" and "bus_a_clk"
+
+Example:
+
+soc {
+ ...
+ bimc: interconnect@...000 {
+ reg = <0x00400000 0x80000>;
+ compatible = "qcom,qcs404-bimc";
+ #interconnect-cells = <1>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_BIMC_CLK>,
+ <&rpmcc RPM_SMD_BIMC_A_CLK>;
+ };
+
+ pnoc: interconnect@...000 {
+ reg = <0x00500000 0x15080>;
+ compatible = "qcom,qcs404-pcnoc";
+ #interconnect-cells = <1>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_PNOC_CLK>,
+ <&rpmcc RPM_SMD_PNOC_A_CLK>;
+ };
+
+ snoc: interconnect@...000 {
+ reg = <0x00580000 0x23080>;
+ compatible = "qcom,qcs404-snoc";
+ #interconnect-cells = <1>;
+ clock-names = "bus_clk", "bus_a_clk";
+ clocks = <&rpmcc RPM_SMD_SNOC_CLK>,
+ <&rpmcc RPM_SMD_SNOC_A_CLK>;
+ };
