class HdmiHost
Defined at line 58 of file ../../src/graphics/display/drivers/amlogic-display/hdmi-host.h
HdmiHost has access to the amlogic/designware HDMI block and controls its
operation. It also handles functions and keeps track of data that the
amlogic/designware block does not need to know about, including clock
calculations (which may move out of the host after https://fxbug.dev/42148166 is resolved),
VPU and HHI register handling, HDMI parameters, etc.

void HdmiHost (std::unique_ptr<HdmiTransmitter> hdmi_transmitter, fdf::MmioBuffer vpu_mmio, fdf::MmioBuffer hhi_mmio, fdf::MmioBuffer gpio_mux_mmio)
`hdmi_transmitter` must not be null.
`vpu_mmio` is the VPU MMIO register region. It must be a valid MMIO buffer.
`hhi_mmio` is the HHI (HIU) MMIO register region. It must be a valid MMIO
buffer.
`gpio_mux_mmio` is the GPIO Multiplexer (PERIPHS_REGS) MMIO register
region. It must be a valid MMIO buffer.
The VPU, HIU and PERIPHS_REGS register regions are defined in Section 8.1
"Memory Map" of the AMLogic A311D datasheet.

zx_status_t ModeSet (const display::DisplayTiming & timing)
Configures the HDMI clock, encoder and physical layer to given `timing`.
Returns ZX_OK and configures the video output module iff the display
timing and clock of `timing` is supported.

bool IsDisplayTimingSupported (const display::DisplayTiming & timing)
Returns true iff a display timing is supported by the display engine driver
and can be used in a display configuration.
