I plan to squash this into\nv3 of the SoftISP series.\n\nSince the standard bayer pattern debayer functions now take an array\nof 3 src pointers (previous-, current- and next-line) we can easily\navoid the need to have 2 lines (2 to keep the pattern unchanged)\npadding at the top / bottom.\n\nThis allows the output to be 4 lines higher, which is esp. useful\nwith the current hi556 kernel driver which has a max-height for\nthe bauer data of 722 lines. So before this change it was not\npossible to generate a standard 1280x720 output.\n\nRegards,\n\nHans\n\n\nHans de Goede (2):\n libcamera: debayer: Move sizes() to DebayerCpu implementation\n libcamera: debayer_cpu: Stop requiring 2 lines of padding at the\n top/bottom\n\n .../libcamera/internal/software_isp/debayer.h | 26 +-----\n .../internal/software_isp/debayer_cpu.h | 4 +-\n src/libcamera/software_isp/debayer_cpu.cpp | 90 +++++++++++++++++--\n 3 files changed, 86 insertions(+), 34 deletions(-)" }
