Hi,
After adding the driver to the kernel 2.6.35 in our custom design, could you give me a more complete example, based in example extracted from ADV7511 HDMI transmitter Linux Driver [Analog Devices Wiki] , view down, to initialize the DRM and DAI configuration, ie a practical example in a Linux to check that the hardware for the ADV7513 is correct once the driver has been installed? What Include files are necesaries...

 

static const uint16_t adv7511_csc_ycbcr_to_rgb[] = {     0x0734, 0x04ad, 0x0000, 0x1c1b,     0x1ddc, 0x04ad, 0x1f24, 0x0135,     0x0000, 0x04ad, 0x087c, 0x1b77,}; static const struct adv7511_video_input_config adv7511_config_zc702 = {     .id = ADV7511_INPUT_ID_16_20_24BIT_YCbCr422_SEPARATE_SYNC,     .input_style = ADV7511_INPUT_STYLE1,     .sync_pulse = ADV7511_INPUT_SYNC_PULSE_NONE,     .clock_delay = ADV7511_INPUT_CLOCK_DELAY_NONE,     .reverse_bitorder = false,     .vsync_polarity = ADV7511_SYNC_POLARITY_HIGH,     .hsync_polarity = ADV7511_SYNC_POLARITY_HIGH,     .up_conversion = ADV7511_UP_CONVERSION_ZERO_ORDER,     .input_color_depth = ADV7511_INPUT_COLOR_DEPTH_8BIT,     .output_format = ADV7511_OUTPUT_FORMAT_RGB_444,     .csc_enable = true,     .csc_coefficents = adv7511_csc_ycbcr_to_rgb,     .csc_scaling_factor = ADV7511_CSC_SCALING_4,     .bit_justification = ADV7511_INPUT_BIT_JUSTIFICATION_RIGHT,     .tmds_clock_inversion = true,}; [...]     struct drm_encoder_slave_funcs *sfuncs = get_slave_funcs(encoder);       sfuncs->set_config(encoder, &adv7511_config_zc702);
