Instead of changing the binding, it may be better to leave it as is and
ignore the first reg property in the driver. Then you don't need any DTS
patch or binding patch. You can just have this one patch. After that you
can introduce a new compatible string for the proper design and make it
have only a single reg property and deprecate the old binding. The
driver can then pick index 0 if the new compatible is present.
Thanks for comment,
The main issue with sc7280.dtsi file.
Required to upstream remoteproc_adsp node for audioreach adsp based
solution.
The base address for remoteproc_adsp dts node is 0x3000000.
Please refer below link audioreach dts patch:
https://patchwork.kernel.org/project/linux-arm-msm/patch/1675700201-12890-4-git-send-email-quic_srivasam@xxxxxxxxxxx/
remoteproc_adsp: remoteproc@3000000 {
compatible = "qcom,sc7280-adsp-pil";
reg = <0 0x03000000 0 0x5000>, <0 0x0355b000 0 0x10>;
reg-names = "qdsp6ss_base", "lpass_efuse";
and in sc7280.dtsi lpasscc node base address also same.
lpasscc: lpasscc@3000000 {
compatible = "qcom,sc7280-lpasscc";
reg = <0 0x03000000 0 0x40>,
<0 0x03c04000 0 0x4>,
In single dtsi file should not have same physical address node.
Required to sort the nodes based on physical address.
As the qdsp6ss clocks are being enabled in remoteproc driver,
removing the qdsp6ss reg region from lpasscc in sc7280.dtsi.
