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. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Acked-by: Tony Lindgren <tony@atomide.com>
