Subject: [PATCH v6 00/10] PCI: rcar-gen4: Add R-Car Gen4 PCIe support
Date: Thu, 22 Sep 2022 17:06:37 +0900 [thread overview]
Message-ID: <20220922080647.3489791-1-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.
Base kernel is the same as v5.
Changes from v5:
https://lore.kernel.org/all/20220905071257.1059436-1-yoshihiro.shimoda.uh@renesas.com/
- No treewide patches.
- Drop PCI_EXP_LNKCAP_MLW_X32 in patch [03/10].
- Add Acked-by in patch [03/10].
- Fix subject prefix in patch [04/10], [05/10], [08/10] and [09/10].
- Fix typo in patch [05/10] and [07/10].
Changes from v4:
https://lore.kernel.org/all/20220722110744.2274466-1-yoshihiro.shimoda.uh@renesas.com/
- Rebased on next-20220901.
-- And based on the following patches:
[PATCH v5 00/20] PCI: dwc: Add generic resources and Baikal-T1 support
https://lore.kernel.org/linux-pci/20220822184701.25246-1-Sergey.Semin@baikalelectronics.ru/
[PATCH RESEND v5 00/24] dmaengine: dw-edma: Add RP/EP local DMA controllers support
https://lore.kernel.org/dmaengine/20220822185332.26149-1-Sergey.Semin@baikalelectronics.ru/
- Notes that snps,dw-pcie-common.yaml modification seems under construction
so that dt-bindings of R-Car Gen4 is based on next-20220901.
