All of these lefovers have been fixed in this patchset. Namely the series starts with two bug-fixes. The first one concerns the improper link-mode initialization in case if the CDM-check is enabled. The second unfortunate mistake I made in the IP-core version type helper. In particular instead of testing the IP-core version type the macro function referred to the just IP-core version which obviously wasn't what I intended. Afterwards two @Mani-noted fixes follow. Firstly the dma-ranges related warning message is fixed to start with "DMA-ranges" word instead of "Dma-ranges". Secondly the Baikal-T1 PCIe Host driver is converted to perform the asynchronous probe type which saved us of about 15% of bootup time if no any PCIe peripheral device attached to the port. Then the patchset contains the Baikal-T1 PCIe driver fix. The corresponding patch removes the false error message printed during the controller probe procedure. I accidentally added the unconditional dev_err_probe() method invocation. It was obviously wrong. Then two trivial cleanups are introduced. The first one concerns the duplicated fast-link-mode flag unsetting. The second one implies dropping a redundant empty line from the dw_pcie_link_set_max_speed() function. The series continues with a patch inspired by the last @Bjorn note regarding the generic resources request interface. As @Bjorn correctly said it would be nice to have the new interface used wider in the DW PCIe subsystem. Aside with the Baikal-T1 PCIe Host driver the Toshiba Visconti PCIe driver can be easily converted to using the generic clock names. That's what is done in the noted patch. The patchset is closed with a series of MAINTAINERS-list related patches. Firstly after getting the DW PCIe RP/EP DT-schemas refactored I forgot to update the MAINTAINER-list with the new files added in the framework of that procedure. All the snps,dw-pcie* schemas shall be maintained by the DW PCIe core driver maintainers. Secondly seeing how long it took for my patchsets to review and not having any comments from the original driver maintainers I'd suggest to add myself as the reviewer to the DW PCIe and eDMA drivers. Thus hopefully the new updates review process will be performed with much less latencies. For the same reason @Manivannan is added to the maintainers list of the DW PCIe/eDMA drivers as he already agreed to be in.
