Subject: [PATCH v4 7/7] arm64: tegra: Add PWM controllers on Tegra264
Date: Tue, 31 Mar 2026 11:12:19 +0900	[thread overview]
Message-ID: <20260331-t264-pwm-v4-7-c041659677cf@nvidia.com> (raw)
In-Reply-To: <20260331-t264-pwm-v4-0-c041659677cf@nvidia.com>

From: Thierry Reding <treding@nvidia.com>

Tegra264 has a number of PWM controllers that are similar but
incompatible with those found on earlier chips.
