Subject: [PATCH v8 0/6] PCI: rcar-gen4: Add R-Car Gen4 PCIe support
Date: Tue, 31 Jan 2023 18:55:37 +0900	[thread overview]
Message-ID: <20230131095543.1831875-1-yoshihiro.shimoda.uh@renesas.com> (raw)

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".
