Subject: [PATCH 0/3] OMAPDSS: HDMI: HDMI Hot-plug detect support.
Date: Tue, 13 Dec 2011 18:54:55 +0530	[thread overview]
Message-ID: <1323782698-24428-1-git-send-email-mythripk@ti.com> (raw)

From: Mythri P K <mythripk@ti.com>

HDMI even if enabled by default should be powered on only when the cable is
connected. This is supported by the Hot-plug feature.
Now when HDMI is enabled the following steps are followed:
-Display enable for HDMI is based on Hot-plug-detect(HPD).
-It registers to the GPIO irq handler and checks if cable is connected,
	-If yes then it turns on HDMI
-If an HPD interrupt is received the corresponding IRQ handler is called where
it checks if it is a connect / disconnect based on which appropriate action
is taken.
