PCI: endpoint: add D-state change notifier support

expand
|
In this series we added the support to nofity the EPF driver whenever there is change in the D-state if the EPF driver registered for it. This series needed by the following series for epf driver to know whether link is in D3Cold or D3hot to wake the host because EPF driver needs to send PME when the link is D3hot and toggle wake when the link is in D3Cold('PCI: EPC: Add support to wake up host from D3 states'). The following link is for older series a newer series will be sent after rebasing on this series. https://lore.kernel.org/linux-pci/1690952359-8625-4-git-send-email-quic_krichai@quicinc.com/T/ Signed-off-by: Krishna chaitanya chundru <quic_krichai@quicinc.com> --- Changes from v6: - Rebased on linux next. - Link to v6: https://lore.kernel.org/all/20230908-dstate_change-v6-0-b414a6edd765@quicinc.com/T/ Changes from v5: - Fixed compilation errors & removed checks in the dstate_notify() function as suggested by bjorn. --- Krishna chaitanya chundru (4): PCI: endpoint: Add D-state change notifier support PCI: qcom-ep: Add support for D-state change notification PCI: qcom-ep: Print D-state name to distinguish D3hot/D3cold PCI: epf-mhi: Add support for handling D-state notify from EPC Documentation/PCI/endpoint/pci-endpoint.rst | 3 +++ drivers/pci/controller/dwc/pcie-qcom-ep.c | 10 ++++++++-- drivers/pci/endpoint/functions/pci-epf-mhi.c | 11 +++++++++++ drivers/pci/endpoint/pci-epc-core.c | 24 ++++++++++++++++++++++++ include/linux/mhi_ep.h | 3 +++ include/linux/pci-epc.h | 2 ++ include/linux/pci-epf.h | 2 ++ 7 files changed, 53 insertions(+), 2 deletions(-) --- base-commit: 82d01fe6ee52086035b201cfa1410a3b04384257 change-id: 20240710-dstate_notifier-2c2f4e2b4eed Best regards,
