We have tested this on LeMans EVK board and qcs8300-ride board and Hamoa EVK board with 'Test Pattern Generator'. Unlike CSID TPG, this TPG can be seen as a combination of CSIPHY and sensor. Tested with following commands: - media-ctl --reset - media-ctl -V '"msm_tpg0":0[fmt:SRGGB10/4608x2592 field:none]' - media-ctl -V '"msm_csid0":0[fmt:SRGGB10/4608x2592 field:none]' - media-ctl -V '"msm_vfe0_rdi0":0[fmt:SRGGB10/4608x2592 field:none]' - media-ctl -l '"msm_tpg0":1->"msm_csid0":0[1]' - media-ctl -l '"msm_csid0":1->"msm_vfe0_rdi0":0[1]' - v4l2-ctl -d /dev/v4l-subdev4 -c test_pattern=9 - yavta -B capture-mplane -n 5 -f SRGGB10P -s 4608x2592 /dev/video2 --capture=7 Changes in V7: - Add TPG support for Hamoa - Add differentiation of register bitfields based on hardware version number. - Fix the null pointer issue when TPG clock is 0. - Correct the clock dependency for TPG. - Link to V6: https://lore.kernel.org/all/20251114-camss_tpg-v6-0-38d3d9fbe339@oss.qualcomm.com/ Changes in V6: - Addressed comments from Bryan and Konrad. - Add exception handling for the streamon format. - Link to V5: https://lore.kernel.org/all/20251017-camss_tpg-v5-0-cafe3ad42163@oss.qualcomm.com/ Changes in V5: - Modify the commit message and change the chip names to LeMans and Monaco. - Add the header file to resolve the compilation error. - Remove the definition where tpg_num is 0. - Link to v4: https://lore.kernel.org/all/20250925-camss_tpg-v4-0-d2eb099902c8@oss.qualcomm.com/ Changes in V4: - Rebase changes - Use GENMASK to define bit fields and avoid using tabs.
