Subject: [PATCH] AT91: Add VSYNC pin definition for AT91SAM9263 silicon
Date: Wed, 25 May 2011 14:31:41 +0800	[thread overview]
Message-ID: <1306305101-27285-1-git-send-email-hong.xu@atmel.com> (raw)

On Atmel's AT91SAM9263-EK board, the LCD panel does not need VSYNC
signal. But this signal is useful for the boards from other
vendors, as suggested by Nicholas Kinar.

This small patch adds the VSYNC pin definition by default.
