There doesn't seem to be an actual version register we could read that information from, so allow the match_data to carry that information for future differentiation. Also carry that information in the hw_revision field of the media- controller API, so that userspace also has access to that. The added versions are: - V10: at least rk3288 + rk3399 - V11: seemingly unused as of now, but probably appeared in some soc - V12: at least rk3326 + px30 - V13: at least rk1808 Signed-off-by: Heiko Stuebner Reviewed-by: Ezequiel Garcia --- Documentation/admin-guide/media/rkisp1.rst | 15 +++++++++++++ .../platform/rockchip/rkisp1/rkisp1-dev.c | 21 +++++++++++-------- include/uapi/linux/rkisp1-config.h | 7 +++++++ 3 files changed, 34 insertions(+), 9 deletions(-) diff --git a/Documentation/admin-guide/media/rkisp1.rst b/Documentation/admin-guide/media/rkisp1.rst index 2267e4fb475e..e960678f47ca 100644 --- a/Documentation/admin-guide/media/rkisp1.rst +++ b/Documentation/admin-guide/media/rkisp1.rst @@ -13,6 +13,21 @@ This file documents the driver for the Rockchip ISP1 that is part of RK3288 and RK3399 SoCs.
