Subject: [U-Boot] [PATCH] RFC: rockchip: video: Lower hpd wait time
Date: Sun, 28 Feb 2016 22:40:02 +0100	[thread overview]
Message-ID: <1456695602-1520-1-git-send-email-sjoerd.simons@collabora.co.uk> (raw)

Waiting 30 seconds for the hpd to go high seems a bit much, especially
on headless boots. Lowering the timeout to 300ms.

Sending as RFC because frankly i don't know what a sensible timeout is
here, but 30 seconds is clearly not it :)
