net: stmmac: dwc-qos: avoid clk and reset for acpi device (1d4605e0) · Commits · 戴 / test

There are no clocks, resets or gpios referenced by Tegra ACPI device so don't access clocks, resets or gpios interface with ACPI device. Clocks, resets and GPIOs for ACPI devices will be handled via ACPI interface. Signed-off-by:
