VPE and VIP IPs in DAR7x contain a scaler(SC) sub block. Create a library which will perform scaler block related configurations and hold SC register definitions. The functions provided by this library will be called by the vpe and vip drivers using a sc_data handle. The vpe_dev holds the sc_data handle. The handle represents an instance of the SC hardware, and the vpe driver uses it to access the scaler register offsets or helper functions to configure these registers. We move the SC register definitions to sc.h so that they aren't specific to VPE anymore. The register offsets are now relative to the sub-block, and not the VPE IP as a whole. In order for VPDMA to configure registers, it requires it's offset from the top level VPE module. A macro called GET_OFFSET_TOP is added to return the offset of the register relative to the VPE IP.

The (d)qbuf ioctls were traced in the low-level v4l2 ioctl function. The trace was outside the serialization lock, so that can affect the usefulness of the timing. In addition, the __user pointer was expected instead of a proper kernel pointer. By moving the tracepoints to video_usercopy we ensure that the trace calls use the correct kernel pointer, and that it happens right after the ioctl call to the driver, so certainly inside the serialization lock. In addition, we only trace if the call was successful. Signed-off-by:

The correct LLC DLL phase depends on the board layout, so this should be part of the platform_data. Also updated the platform_data in ezkit to ensure that what was the old default value is now explicitly specified, so the behavior for that board is unchanged. Tested-by:

The STDI block may measure wrong values, especially for lcvs and lcf. If the driver can not find any valid timing, the STDI block is restarted to measure the video timings again. The function will return an error, but the restart of STDI will generate a new STDI interrupt and the format detection process will restart. Copied from adv7604. Signed-off-by:

Both the PAL and NTSC standards are interlaced where a frame consist of two fields. Total number of lines in a frame in both systems are an odd number so the two fields will have different length. In the 625 line standard ("PAL") the odd field of the frame is transmitted first, while in the 525 standard ("NTSC") the even field is transmitted first. This adds the possibility to change output config between the fields and standards. This setting will reduce the "format-jitter" on the signal sent by the pixelport moving the difference between the fields to vertical front/back-porch only. Signed-off-by: -

Added support for YCrCb analog input. If input is ADV7842_MODE_RGB and RGB quantization range is set to V4L2_DV_RGB_RANGE_AUTO, then video with CEA timings will be received as RGB. For ADV7842_MODE_COMP, automatic CSC mode will be selected. See table 48 on page 281 in "ADV7842 Hardware Manual, Rev. 0, January 2011" for details. Make sure that when switching inputs the RGB quantization range is updated as well. Also updated the platform_data in ezkit to ensure that what was the old default value is now explicitly specified, so the behavior for that board is unchanged. Signed-off-by:

The method of disabling the irq-output pin caused many "empty" interrupts. Instead, actually disable/enable the interrupts by changing the interrupt masks. Also enable STORE_MASKED_IRQ in INT1 configuration, otherwise when HDMI events happen while the interrupt is masked those events will be ignored when the interrupt is unmasked. Signed-off-by:

ADV7604_FMT_CHANGE events was debounced in adv7604_isr() to avoid that a receiver with a unstable input signal would block the event handling for other inputs. This solution was prone to errors. A better protection agains interrupt blocking is to delay the call of the interrupt service routine in the adv7604 driver if too many interrupts are received within a given time. Signed-off-by:
