[PATCH v2 1/4] ARM: dts: exynos: Enable HDMI for Arndale Octa board

Show all headers | View raw

* Support HDMI display data channel
  I2C #2 is assigned for the HDMI DDC. It enables the EDID access.

* GPIO for HDMI hot plug detect
  GPX3_7 is used. The HPD awareness is done when the GPIO is active high and
  single ended.

* Enable HDMI block in Exynos5420
  HDMI PLL consumes 1.0V LDO6 (PVDD_ANAIP_1V0) and HDMI oscillator requires
  1.8V LDO7 (PVDD_ANAIP_1V8).
