Commit deb65870b5d9d ("drm/imx: imx-tve: check the value returned by regulator_set_voltage()") exposes the following probe issue:
63ff0000.tve supply dac not found, using dummy regulator imx-drm display-subsystem: failed to bind 63ff0000.tve (ops imx_tve_ops): -22
When the 'dac' regulator is not passed in the device tree, devm_regulator_get() will return NULL and when regulator_set_voltage() is called it returns an error.
Fix the issue by making the 'dac' regulator optional.
