The mismatch happens because the current code\ndoes not check if the configured format exceeds the maximum viable\nresolution of the ISP.\n\nMake sure to use a sensor format resolution that is smaller or equal to\nthe maximum allowed resolution for the RkISP1. The maximum resolution\nis defined within the `rkisp1-common.h` file as:\ndefine RKISP1_ISP_MAX_WIDTH 4032\ndefine RKISP1_ISP_MAX_HEIGHT 3024\n\nEnumerate the frame-sizes of the ISP entity and compare the maximum with\nthe configured resolution.\n\nThis means that some camera sensors can never operate with their maximum\nresolution, for example on my OV13850 camera sensor, there are two\npossible resolutions: 4224x3136 & 2112x1568, the first of those two will\nnever be picked as it surpasses the maximum of the ISP.\n\nSigned-off-by: Sebastian Fricke <sebastian.fricke.linux@gmail.com>\n---\n\nAttention: This patch depends on the following patch for the Linux\nKernel media subsystem.\nhttps://patchwork.kernel.org/project/linux-media/patch/20201212185306.19135-1-sebastian.fricke.linux@gmail.com/\n\nv1: https://lists.libcamera.org/pipermail/libcamera-devel/2020-November/015113.html\nv2: https://lists.libcamera.org/pipermail/libcamera-devel/2020-November/015136.html\n\nChangelog:\n\nChanges since v2:\n\n* Replace the act of attempting to set the ISP format before negotiating\n the actual format for both the ISP input pad and the sensor in order\n to get the maximum frame size. With a logic that involves enumerating\n the maximum size directly from the subdevice and using that size for\n the negotiation process.\n* Improve the log messages\n\nChanges since v1:\n\n* Change snake_case variable names to camelCase\n* Use the request comment style\n* Correct the scope of the newly implemented variables\n* Correct the subject of the debug log for the ISP format configuration\n* Update the comment above the ISP format configuration\n* Check if the original format is not equal to the configured ISP format\n instead of checking if it is greater, this denies a false positive\n where the height exceeds the maximum while the width is smaller.\n If the configured format does not exceed the maximum resolution of the\n ISP, it will stay untouched so the inequality always means that we\n have to reconfigure the format.\n* Adjust the comparison of the ISP format size with the available sensor\n formats, to detect a false-positive were the width is smaller while\n the height exceeds the maximum\n* Use the standard function `max`\n\n-----\n\nThe following tests were all able to create a working camera pipeline:\n1. Without stream configuration\n2. With a normal stream configuration\n3. With a stream configuration that exceeds the maximum of the ISP\n4. With a very small resolution stream configuration\n5. With a configuration that is closer to the upper than to the lower\nresolution\n\n-----\n\n1.
