Subject: [PATCH v3 0/5] PCI: tegra: A couple of cleanups
Date: Tue, 24 Feb 2026 17:48:56 +0530	[thread overview]
Message-ID: <20260224121948.25218-1-linux.amoon@gmail.com> (raw)

Hi All,

This small series provides two cleanup patches for the Tegra PCIe driver.
The overall goal is to replace custom, open-coded logic with standard
kernel helper functions.

These changes improve the driver's readability and maintainability by
everaging modern, well-tested APIs for clock management and register
polling.

v3: Fix the DT binding for nvidia,tegra-pcie.yaml
    tried to address issue for Krzysztof and Jon.
    Added missing regulator and new patch to fix the device tree check.
    Added missing entry in MAINTAINERS.

v2: Fix the DT binding for nvidia,tegra-pcie.yaml
    switch back to devm_clk_bulk_get_all to get all the clocks
    improve the commit message.

v1 Added new devicetree binding nvidia,tegra-pcie.yaml file.
   Switch from devm_clk_bulk_get_all() -> devm_clk_bulk_get() api.
   Fixed checkpatch warnings.

Tested on Jetson Nano 4 GB ram.
