drm_dp_dual_mode_max_tmds_clock — Max TMDS clock for DP dual mode adaptor
int drm_dp_dual_mode_max_tmds_clock ( | enum drm_dp_dual_mode_type type, |
struct i2c_adapter * adapter) ; |
Determine the max TMDS clock the adaptor supports based on the
type of the dual mode adaptor and the DP_DUAL_MODE_MAX_TMDS_CLOCK
register (on type2 adaptors). As some type 1 adaptors have
problems with registers (see comments in drm_dp_dual_mode_detect
)
we don't read the register on those, instead we simply assume
a 165 MHz limit based on the specification.
