It takes me so long to figure out i.MX6 mipi csi controller must set correct dphy frequency to match the mipi device output.
My question is, how can I just set mipi dphy frequency without reload my driver? since ADV7480 can transfer any resolution, it's not convenient to reload the module for change i.MX6 mipi csi controller's dphy freq register.
I tried only calling mipi_csi2_write(info, 0x00000014, CSI2_PHY_TST_CTRL1); by replacing the 0x14 to another value, but it won't work.
Any suggestions is welcome, thanks.
