Date: Thu, 7 Aug 2025 16:43:50 -0500 [thread overview]
Message-ID: <20250807214351.4172243-1-robh@kernel.org> (raw)
The nvidia,tegra20-ehci binding is already documented in
ci-hdrc-usb2.yaml, so drop the old text binding.

-SOC is as described in the document "Open Firmware Recommended
-Practice : Universal Serial Bus" with the following modifications
-and additions :
-
-Required properties :
- - compatible : For Tegra20, must contain "nvidia,tegra20-ehci".
- For Tegra30, must contain "nvidia,tegra30-ehci". Otherwise, must contain
- "nvidia,<chip>-ehci" plus at least one of the above, where <chip> is
- tegra114, tegra124, tegra132, or tegra210.
- - nvidia,phy : phandle of the PHY that the controller is connected to.
- - clocks : Must contain one entry, for the module clock.
- See ../clocks/clock-bindings.txt for details.
- - resets : Must contain an entry for each entry in reset-names.
- See ../reset/reset.txt for details.
- - reset-names : Must include the following entries:
