The first patch is the start of the work discussed in the "[RFC] Repurpose V4L2_CID_PIXEL_RATE for the sampling rate in the pixel array" thread [1]. I plan to send a few other similar patches for other CSI receiver drivers, and if the current patchset needs to wait for those before it can be merged, that's fine for me. The reason I decided to post the camss patch first is the patch [2] by Vladimir Lypak. The second patch in this series is the Vladimir's patch rebased onto the changes done by the first patch. By replacing getting the pixel clock with v4l2_get_link_freq() my first patch also fixes the integer overflow which Vladimir's patch addresses. So the second patch only needs to fix drivers/media/platform/qcom/camss/camss-vfe.c which the first patch doesn't touch. The resulting patchset is free from the "undefined reference to `__udivdi3'" issue [3] as the u64 value is only divided by a power of 2, which doesn't need do_div(). Vladimir, please confirm if this patchset fixes the integer overflow for you, and if you are OK with your patch going on top of mine like is done in this patchset.
