From: "Dr. David Alan Gilbert" <linux@xxxxxxxxxxx> ipu_csi_get_window(), ipu_csi_is_interlaced() and ipu_csi_set_test_generator() were added in 2014 by commit 2ffd48f2e7ae ("gpu: ipu-v3: Add Camera Sensor Interface unit") but have remained unused. Remove them. ipu_csi_set_testgen_mclk() is now unused. Remove it.
