Allwinner V3s SoC features two CSI module. CSI0 is used for MIPI CSI-2 interface and CSI1 is used for parallel interface. This is not documented in datasheet but by test and guess. This patchset implement a v4l2 framework driver and add a binding documentation for it. Currently, the driver only support the parallel interface. And has been tested with a BT1120 signal which generating from FPGA. The following fetures are not support with this patchset: - ISP - MIPI-CSI2 - Master clock for camera sensor - Power regulator for the front end IC Changes in v9: * Merge the patchs from Maxime: a. Fill dma_pfn_offset to accomodate for the RAM offset b. Reduce the error level c. Pass the sun6i_csi_dev pointer to our helpers d. Don't emit a warning when the configured format isn't found e. Support the YUYV format properly f. Invert the polaritie of all signals g. Expose controls on the v4l2_device Changes in v8: * Revert to v6 and add 'hack' for PHYS_OFFSET. Changes in v7: * Add 'depends on ARM' in Kconfig to avoid built with non-ARM arch. Changes in v6: * Add Rob Herring's review tag. * Fix a NULL pointer dereference by picking Maxime Ripard's patch. * Add Maxime Ripard's test tag. Changes in v5: * Using the new SPDX tags. * Fix MODULE_LICENSE. * Add many default cases and warning messages. * Detail the parallel bus properties * Fix some spelling and syntax mistakes. Changes in v4: * Deal with the CSI 'INNER QUEUE'. CSI will lookup the next dma buffer for next frame before the the current frame done IRQ triggered. This is not documented but reported by Ondřej Jirman. The BSP code has workaround for this too. It skip to mark the first buffer as frame done for VB2 and pass the second buffer to CSI in the first frame done ISR call. Then in second frame done ISR call, it mark the first buffer as frame done for VB2 and pass the third buffer to CSI. And so on. The bad thing is that the first buffer will be written twice and the first frame is dropped even the queued buffer is sufficient. So, I make some improvement here. Pass the next buffer to CSI just follow starting the CSI. In this case, the first frame will be stored in first buffer, second frame in second buffer. This mothed is used to avoid dropping the first frame, it would also drop frame when lacking of queued buffer. * Fix: using a wrong mbus_code when getting the supported formats * Change all fourcc to pixformat * Change some function names Changes in v3: * Get rid of struct sun6i_csi_ops * Move sun6i-csi to new directory drivers/media/platform/sunxi * Merge sun6i_csi.c and sun6i_csi_v3s.c into sun6i_csi.c * Use generic fwnode endpoints parser * Only support a single subdev to make things simple * Many complaintion fix Changes in v2: * Change sunxi-csi to sun6i-csi * Rebase to media_tree

Pass the next buffer to CSI just follow starting the CSI. In this case, the first frame will be stored in first buffer, second frame in second buffer. This mothed is used to avoid dropping the first frame, it would also drop frame when lacking of queued buffer. * Fix: using a wrong mbus_code when getting the supported formats * Change all fourcc to pixformat * Change some function names Changes in v3: * Get rid of struct sun6i_csi_ops * Move sun6i-csi to new directory drivers/media/platform/sunxi * Merge sun6i_csi.c and sun6i_csi_v3s.c into sun6i_csi.c * Use generic fwnode endpoints parser * Only support a single subdev to make things simple * Many complaintion fix Changes in v2: * Change sunxi-csi to sun6i-csi * Rebase to media_tree master branch Following is the 'v4l2-compliance -s -f' output, I have test this with both interlaced and progressive signal: #
