HHI_HDMI_PLL_CNTL2 - HDMI PLL Control Register 2.

The datasheets only provide names for each field without any other per-field

definition. Field documentation in this class is only speculation based on

the abbreviations and behavior of Amlogic-provided code, and may not reflect

the actual hardware configuration.

SelfType & set_spread_range_multiplier (typename SelfType::ValueType val)

Spread range multiplier.

From Amlogic-provided code, the spread range can be calculated as

spread range (ppm) = 500 * `spread_spectrum_selection` * `spread_range_multiplier`.

where 1ppm = 10^-6.

The valid range of `spread_range_multiplier` is unknown.

Known as "ssc_str_m" in datasheets.

spread range (ppm) = 500 * `spread_spectrum_selection` * `spread_range_multiplier`.

where 1ppm = 10^-6.

The valid range of `spread_range_multiplier` is unknown.

SelfType & set_spread_spectrum_clocking_enabled (typename SelfType::ValueType val)

Enables spread spectrum clocking.

Known as "ssc_en" in datasheets.

typename SelfType::ValueType spread_spectrum_clocking_enabled ()

Enables spread spectrum clocking.

template <, >

SelfType & set_spread_range_selection (typename SelfType::ValueType val)

Spread range selector, where 1 stands for 500 ppm, 2 stands for 1000 ppm,

and `n` stands for `n * 500` ppm.

Together with `spread_range_multiplier`, it determines the spectrum spread

range.

The valid range of `spread_range_selection` is unknown.

Known as "ssc_dep_sel" in datasheets.
