Subject: [PATCH] ARM: dts: davinci: da850-evm: Increase fifo threshold
Date: Sun, 4 May 2025 05:29:59 -0500 [thread overview]
Message-ID: <20250504102959.81830-1-aford173@gmail.com> (raw)
When operating at low speeds, the display may throw an underflow
error and the display itself goes blank. Increasing the fifo-th
value appears to correct this problem and the display can now
operate when the system is operating at speeds as low as 100MHz.
