Subject: [PATCH] ARM: dts: davinci: da850-evm: Increase fifo threshold
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.
