* Description:
|
|
* Structure holding timing and resolution information of a standard.
|
|
* Used by vpbe_device to set required non-standard timing in the
|
|
* venc when lcd controller output is connected to a external encoder.
|
|
* A table of timings is maintained in vpbe device to set this in
|
|
* venc when external encoder is connected to lcd controller output.
|
|
* Encoder may provide a g_dv_timings() API to override these values
|
|
* as needed.
|
|
*
|
|
* Notes
|
|
* ------
|
|
* if_type should be used only by encoder manager and encoder.
|
|
* flags usage
|
|
* b0 (LSB) - hsync polarity, 0 - negative, 1 - positive
|
|
* b1 - vsync polarity, 0 - negative, 1 - positive
|
|
* b2 - field id polarity, 0 - negative, 1 - positive
