From 8a3d895bfe409f3cae398c0788e8639260c81754 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Wed, 15 Aug 2012 15:54:53 +0300 Subject: [PATCH] OMAP4: TWL: add vdda_hdmi_dac regulator supply HDMI requires vdda_hdmi_dac (vdac) power for operation. The regulator, or the regulator supplying the vdac, has been enabled by default and things have worked without the HDMI driver enabling the vdac. I encountered the problem when implementing HDMI device tree support, where the regulator was not enabled by default. This patch adds the vdda_hdmi_dac to twl-common.c so that the HDMI driver can use it.
