[PATCH v4 0/3] gpu: drm: exynos_hdmi: Code refactoring on hdmi ddc and phy

[Milo Kim]

v4:
  Only DRM patchset is sent, DTS patch was sent separately.

Milo Kim (3):
  gpu: drm: exynos_hdmi: Move DDC logic into single function
  gpu: drm: exynos_hdmi: Move PHY logic into single function
  gpu: drm: exynos_hdmi: Remove duplicate initialization of regulator
    bulk consumer
