struct edid * drm_get_edid_switcheroo(struct drm_connector * connector, struct i2c_adapter * adapter);

ARGUMENTS

connector

connector we're probing

adapter

I2C adapter to use for DDC

DESCRIPTION

Wrapper around drm_get_edid for laptops with dual GPUs using one set of outputs. The wrapper adds the requisite vga_switcheroo calls to temporarily switch DDC to the GPU which is retrieving EDID.
