Add proxy interconnect bandwidth votes during modem bootup on SC7280 SoCs.
V2:
* Dropped patch 3 from version 1 [Sub with Bjorn's patch]
* Add YAML support [Krzysztof]
* Drop interconnect names [Bjorn]

I'll re-order the clock names in the bindings and fix the pdc_sync typo in the next re-spin. The interconnects missing warnings should go away since patch 2 adds it. -Sibi On 5/10/22 12:49 AM, Matthias Kaehlcke wrote: > On Mon, May 09, 2022 at 07:20:58AM -0500, Rob Herring wrote: >> On Mon, 09 May 2022 13:23:17 +0530, Sibi Sankar wrote: >>> Add MSS PIL loading bindings for SC7280 SoCs. >>> >>> Signed-off-by: Sibi Sankar <quic_sibis@quicinc.com> >>> --- >>> .../bindings/remoteproc/qcom,sc7280-mss-pil.yaml | 261 +++++++++++++++++++++ >>> 1 file changed, 261 insertions(+) >>> create mode 100644 Documentation/devicetree/bindings/remoteproc/qcom,sc7280-mss-pil.yaml >>> >> >> Running 'make dtbs_check' with the schema in this patch gives the >> following warnings.
