Subject: [PATCH v1 1/1] ARM: tegra: tf700t: Align panel timings with Linux
Date: Wed, 20 May 2026 12:11:55 +0300	[thread overview]
Message-ID: <20260520091155.44696-2-clamor95@gmail.com> (raw)
In-Reply-To: <20260520091155.44696-1-clamor95@gmail.com>

Downstream timings provided by ASUS do not allow enough time for the
bridge to set up properly. Switch to the timings provided by the Linux
kernel's simple panel driver.
