The HPD awareness is done when the GPIO is active high. * Enable HDMI block in Exynos5420 HDMI VDD and PLL consume 1.0V LDO6 (PVDD_ANAIP_1V0) and HDMI oscillator requires 1.8V LDO7 (PVDD_ANAIP_1V8). * Support HDMI display data channel I2C #2 is assigned for the HDMI DDC. It enables the EDID access.
