Subject: [PATCH v2 0/4] Add PCIe support for RZ/V2H(P) SoC
Date: Mon, 18 May 2026 16:53:20 +0100 [thread overview]
Message-ID: <20260518155324.168948-1-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Hi all,
This series adds support for the PCIe host controllers found on the
Renesas RZ/V2H(P) SoCs. The RZ/V2H(P) controller includes additional
features for PCIe lane control and supports multilink operation with
two independent controllers.
v1->v2:
- Dropped RZ/V2N DT binding patch as it has been merged in the
pci/dt-binding branch.
- Dropped un-necessary new line in schema.
- Renamed RZG3S_PCIE_CHANNEL_ID* to RZG3S_PCIE_CONTROLLER_ID* for clarity.
- Added locks to protect shared lane configuration state and
prevent concurrent access issues during probe.
- Added cleanup action to release lanes on driver removal.
- Reconfigured RZG3S_SYSC_FUNC_ID_LINK_MASTER in resume path.
- Renamed num_channels to num_pcie_controllers for clarity.
- Updated commit messages for clarity in patches 1-4.
note, the dt binding patch applies on top of pci/dt-binding branch.
Cheers,
Prabhakar
