So, I'll submit v9 patch soon. Best regards, Yoshihiro Shimoda
Add R-Car S4-8 (R-Car Gen4) PCIe Host and Endpoint support. To support them, modify PCIe DesignWare common codes. Changes from v7: https://lore.kernel.org/all/20221121124400.1282768-1-yoshihiro.shimoda.uh@renesas.com/ - Based on next-20230131. - Update Copyright year of new files. - Add a new capability flag (DW_PCIE_CAP_EDMA_UNROLL) for finding eDMA on R-Car S4-8. - Remove some PCIe configurations like L1 substates from pcie-rcar-gen4-host.c. - Change timing of reset_control for suitable this hardware initialization. - Add gpio reset handling for host mode. - Capitalize the first charactors on each printk message. Changes from v6: https://lore.kernel.org/all/20220922080647.3489791-1-yoshihiro.shimoda.uh@renesas.com/ - Based on next-20221116. -- And based on the following patches: [PATCH v7 00/20] PCI: dwc: Add generic resources and Baikal-T1 support https://lore.kernel.org/linux-pci/20221113191301.5526-1-Sergey.Semin@baikalelectronics.ru/ [PATCH v6 00/24] dmaengine: dw-edma: Add RP/EP local DMA controllers support https://lore.kernel.org/linux-pci/20221107210438.1515-1-Sergey.Semin@baikalelectronics.ru/ - Update dt-bindings docs for the latest based code. - Add support for triggering legacy IRQs in the patch [06/10] (new). - Add .no_msix flag into the patch [07/10]. - Merge .ep_pre_init() support into the patch [08/10]. - Add .reserved_bar for BAR5 instead in the patch [08/10]. - Change SPDX-License-Identifier from "GPL-2.0" to "GPL-2.0-only".
