This patchset is an initial one in the series created in the framework of my Baikal-T1 PCIe/eDMA-related work: [1: In-progress v1] clk: Baikal-T1 DDR/PCIe resets and some xGMAC fixes Link: https://lore.kernel.org/linux-pci/20220324010905.15589-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ [2: In-progress v1] PCI: dwc: Various fixes and cleanups Link: https://lore.kernel.org/linux-pci/20220324012524.16784-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ [3: In-progress v1] PCI: dwc: Add dma-ranges/YAML-schema/Baikal-T1 support Link: https://lore.kernel.org/linux-pci/20220324013734.18234-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ [4: In-progress v1] dmaengine: dw-edma: Add RP/EP local DMA controllers support Link: https://lore.kernel.org/linux-pci/20220324014836.19149-1-Sergey.Semin@xxxxxxxxxxxxxxxxxxxx/ Since some of the patches in the later patchsets depend on the modifications introduced here, @Bjorn could you please merge this series through your PCIe subsystem repo? After getting all the required ack'es of course. Short summary regarding this patchset. A few more modifications are introduced here to finally finish the Baikal-T1 CCU unit support up and prepare the code before adding the Baikal-T1 PCIe/xGMAC support. First of all it turned out I specified wrong DW xGMAC PTP reference clock divider in my initial patches. It must be 8, not 10. Secondly I was wrong to add a joint xGMAC Ref and PTP clock instead of having them separately defined. The SoC manual describes these clocks as separate fixed clock wrappers. Finally in order to close the SoC clock/reset support up we need to add the DDR and PCIe interfaces reset controls support. It's done in two steps. First I've moved the reset-controls-related code into a dedicated module. Then the DDR/PCIe reset-control functionality is added.
