Subject: [PATCH 2/2] pwm: tegra: Opt out of driver_override
Date: Tue, 22 Sep 2026 13:38:29 +0200 [thread overview]
Message-ID: <20260922-driver-override-opt-out-v1-2-58c35ded3b83@nvidia.com> (raw)
In-Reply-To: <20260922-driver-override-opt-out-v1-0-58c35ded3b83@nvidia.com>
From: Thierry Reding <treding@nvidia.com>
The Tegra PWM driver heavily relies on device data obtained through
device ID matching and will not work if this data is missing. Opt out of
the driver_override mechanism to prevent the driver from accidentally
being bound to a device that doesn't match a DT device ID table entry.
