SYNOPSIS

int drm_dp_dual_mode_set_tmds_output(enum drm_dp_dual_mode_type type, struct i2c_adapter * adapter, bool enable);

ARGUMENTS

type

DP dual mode adaptor type

adapter

I2C adapter for the DDC bus

enable

enable (as opposed to disable) the TMDS output buffers

DESCRIPTION

Set the state of the TMDS output buffers in the adaptor. For type2 this is set via the DP_DUAL_MODE_TMDS_OEN register. As some type 1 adaptors have problems with registers (see comments in drm_dp_dual_mode_detect) we avoid touching the register, making this function a no-op on type 1 adaptors.

RETURNS

0 on success, negative error code on failure
