| | | | | | | | | | | | | | When updating the crop rectangle during streaming, the IRQ handler will reprogram the resizer after the current frame. A race condition currently exists between the set selection operation and the IRQ handler: if the set selection operation is called twice in a row and the IRQ handler runs only during the second call, it could reprogram the hardware with partially updated values. Use a spinlock to protect against that.

| | | | | | | | | | | | | | | | | The resizer_set_input_size() function prints a debugging message with the input width and height values. As the function is called from interrupt context, printing that message to the serial console could slow down the interrupt handler and cause it to miss the start of the next frame, causing image corruption. Fix this by reorganizing the resizer debug messages. The driver now prints the input size, the crop rectangle and the output size in the set selection handler instead of scattering debug messages in various places.

| | | | | | | | | | | | | | | In BT.656 mode the synchronization signals are generated by the CCDC from the embedded sync codes. The VD0 and VD1 interrupts are thus only triggered when the CCDC is enabled, unlike external sync mode where the line counter runs even when the CCDC is stopped. We can't disable the CCDC at VD1 time, as no VD0 interrupt would be generated for a short frame, which would result in the CCDC being stopped and no VD interrupt generated anymore.
