Maybe just check for port A in relevant cases and factor out vlv cases completely. My bet is that this massive confusion is the reason that vlv dp (i.e. non-edp) is totally broken atm. -Daniel

Could we do that as a follow-up to this? That work would have also the benefit of removing is_cpu_edp() as you hoped earlier, so it could stand on its own.. --Imre

is_pch_edp() will be removed by the next patch, so replace it by a check for the port and device type. Signed-off-by: Imre Deak <imre.deak@intel.com> --- drivers/gpu/drm/i915/intel_dp.c | 17 +++++++++++------ 1 file changed, 11 insertions(+), 6 deletions(-)
