Generic Display Pipeline are one of the compositor input sub-devices.
GDP are dedicated to graphic input like RGB plans.
GDP is part of Compositor hardware block which will be introduce later.
A sti_layer structure is used to abstract GDP calls from Compositor.

TVout hardware block is responsible to dispatch the data flow coming
from compositor block to any of the output (HDMI or Analog TV).
It control when output are start/stop and configure according the
require flow path.
TVout is the parent of HDMI and HDA drivers and bind them at runtime.
Tvout is mapped on drm_encoder structure.
One encoder is created for each of the sub-devices and link to their
connector/bridge

Add driver for HDMI output.
HDMI PHY registers are mixed into HDMI device registers
and their is only one IRQ for all this hardware block.
That is why PHYs aren't using phy framework but only a
thin hdmi_phy_ops structure with start and stop functions.
HDMI driver is mapped on drm_bridge and drm_connector structures.

Video Time Generator drivers are used to synchronize the compositor
and tvout hardware IPs by providing line count, sample count,
synchronization signals (HSYNC, VSYNC) and top and bottom fields
indication.
VTG are used by pair for each data path (main or auxiliary)
one for master and one for slave.
