+#define OS05B10_PIXEL_RATE (480 * HZ_PER_MHZ)Here pixel rate should not be hardcoded, it'd be computed in runtime as 600MHz * 2 * 4 lanes / 10 bpp = 480MHz. The sensor may be wired over 2 lanes or (presumably) it can stream 8 bpp data.We are not supporting 2 lanes right now, driver supports only for 4 lanes and 10 bpp data. So technically OS05B10_PIXEL_RATE will never change. For reference I will add OS05B10_PIXEL_RATE calculation in comments. I would prefer the hardcoded at the moment. Other than this comment I will resolve and send new version.The pixel rate on the pixel array may be disconnected from the link frequency (and throughput) -- it may be more (with e.g. binning) or less, depending on the sensor of course. Calculating it, if possible, is always better than using a fixed value; experience has shown these are often simply incorrect and sometimes not updated when other changes are made (and same goes for the link frequency).
Okay, I just want to know if this is non-blocking comment and we can go ahead with current version of driver. Meanwhile my colleague Tarang is working on some features and he is planning to send a series on top of this driver. If he takes up this comment in that series will it be okay with you? And also I have already sent next revision v8. Please let me know. -- Best Regards, Himanshu Bhavani
