Subject: [PATCH V2 0/8] PCI: tegra: Add Tegra234 PCIe support
Date: Sat, 23 Apr 2022 18:18:50 +0530 [thread overview]
Message-ID: <20220423124858.25946-1-vidyas@nvidia.com> (raw)
Tegra234 has a total of 11 PCIe controllers based on Synopsys DesignWare core.
There are three Universal PHY (UPHY) blocks (viz. HSIO, NVHS and GBE) with
each block supporting 8 lanes respectively. Controllers:0~4 use UPHY lanes
from HSIO block, Controllers:5,6 use UPHY lanes from NVHS block and
Controllers:7~10 use UPHY lanes from GBE block. Lane mapping in each block
is controlled in XBAR module by BPMP-FW. Since PCIe core has PIPE interface,
a glue module called PIPE-to-UPHY (P2U) is used to connect each UPHY lane
(applicable to all three UPHY bricks i.e. HSIO/NVHS/GBE) to PCIe controller.
This patch series
- Adds support for Tegra234 in the existing P2U PHY driver
- Adds support for Tegra234 in the existing PCIe platform controller driver
- Adds device tree nodes for all PCIe controllers
- Enables nodes applicable to P3737-0000 platform
Testing done on P3737-0000 platform
- PCIe link is up with on-board Broadcom WiFi controller
- PCIe link is up with an NVMe drive connected to M.2 Key-M slot and its
functionality is verified
- PCIe link is up with a variety of cards (NICs and USB3.0 add-on cards)
connected to CEM slot and their functionality is verified
V2:
* Dropped 3 patches that add clocks & resets IDs, power-domain IDs and
memory IDs for PCIe controllers as the patches are already available
in linux-next
* Based on Bjorn's review comment, reverted the commit b57256918399 ("PCI:
tegra194: Rename tegra_pcie_dw to tegra194_pcie") and pushed it as a
separate patch before adding support for T234 in the existing driver
* Addressed review comments from Rob for the other changes
