[0] In addition to prepare the support to px30 (V12 in the uapi) This version of the set adds more fixes to the code in params/stats according to the changes in the uapi and also change the hist_bins to be u32 instead of u16. More details about the patchset can be found in v6's cover-letter [1] [0] https://patchwork.kernel.org/project/linux-media/list/?series=416647 [1] https://patchwork.kernel.org/project/linux-media/cover/20210118110448.275389-1-heiko@sntech.de/ changes since v7: - in patch 1, wrap long lines - add a patch that masks out the unused bits in hist_bins enteries. - in the last patch, in the last patch, remove unneeded memset of the stats arries - no changes in other patches appart of rebase changes since v6: - add a patch to change the hist_bins array type to __u32 and extend the documentation of how the histogram measurements are taken - remove a wrong u8 cast when filling the hist_bins array - when reducing the number of elements in the weight grid array, the code in rkisp1-params.c should be adjusted to iterate it 25 times - some minor typo and checkpatch fixes. changes since v5: - move grid reduction for V10 to separate patch (Hans) - fix commit message (histogram size 28 -> 25) in patch4 (Hans) changes since v4: - set GAMMA_OUT to the real 25 instead of the 28 with 3 spares (Dafna) - start RKISP_Vxx enum with 10 for RKISP_V10 to make output easier and also allow userspace to differentiate between old (= 0) and newer driver variants (Dafna, Laurent) changes since v3: - add patch fixing the original histogram size comment - make comments in uapi more verbose (Hans) - fix wording in admin guide (Hans) - document version <-> soc in uapi as well (easier for people) (Dafna) changes since v2: - actually zero the correct sizes for u16 values (hist-bins) (kernel-test-robot) changes since v1: - drop duplicate isp_ver storage, hw_revision is enough (Dafna) - document multiple maximum sizes in uapi (Hans) - document usage of hw_revision field (Hans) - zero fields transmitted to userspace before adding data (Hans) - use _V10 field sizes when filling fields, as there is only v10 for now changes since rfc: - move rkisp1_version enum into uapo - show version in media-api hw_revision - introduce constants for versions and make max use the biggest Dafna Hirschfeld (3): media: rkisp1: uapi: change hist_bins array type from __u16 to __u32 media: rkisp1: stats: remove a wrong cast to u8 media: rkisp1: stats: mask the hist_bins values Heiko Stuebner (3): media: rockchip: rkisp1: reduce number of histogram grid elements in uapi media: rockchip: rkisp1: carry ip version information media: rockchip: rkisp1: extend uapi array sizes Documentation/admin-guide/media/rkisp1.rst | 16 ++++ .../platform/rockchip/rkisp1/rkisp1-dev.c | 21 +++-- .../platform/rockchip/rkisp1/rkisp1-params.c | 5 +- .../platform/rockchip/rkisp1/rkisp1-regs.h | 1 + .../platform/rockchip/rkisp1/rkisp1-stats.c | 11 +-- include/uapi/linux/rkisp1-config.h | 86 ++++++++++++++++--- 6 files changed, 114 insertions(+), 26 deletions(-)
