media: rkisp1: rsz: crash fix when setting src format

2021-05-14T08:52:35Z

[ Upstream commit cbe8373ca7e7cbb4b263b6bf222ccc19f5e119d2 ] When setting the source media bus code in the resizer, we first check that the current media bus code in the source is yuv encoded format. This is done by retrieving the data from the formats list of the isp entity. This cause a crash when the media bus code on the source is YUYV8_1_5X8 which is not supported by the isp entity. Instead we should test the sink format of the resizer which is guaranteed to be supported by the isp entity.

media: rkisp1: params: fix wrong bits settings

2021-03-11T10:40:29Z

The histogram mode is set using 'rkisp1_params_set_bits'. Only the bits of the mode should be the value argument for that function. Otherwise bits outside the mode mask are turned on which is not what was intended.

media: v4l2-async: Improve v4l2_async_notifier_add_*_subdev() API

2021-02-06T08:18:53Z

The functions that add an async subdev to an async subdev notifier take as an argument the size of the container structure they need to allocate. This is error prone, as passing an invalid size will not be caught by the compiler. Wrap those functions in macros that take a container type instead of a size, and cast the returned pointer to the desired type. The compiler will catch mistakes if the incorrect type is passed to the macro, as the assignment types won't match.

media: v4l2-async: Clean v4l2_async_notifier_add_fwnode_remote_subdev

2021-02-06T07:40:36Z

Change v4l2_async_notifier_add_fwnode_remote_subdev semantics so it allocates the struct v4l2_async_subdev pointer. This makes the API consistent: the v4l2-async subdevice addition functions have now a unified usage model. This model is simpler, as it makes v4l2-async responsible for the allocation and release of the subdevice descriptor, and no longer something the driver has to worry about. On the user side, the change makes the API simpler for the drivers to use and less error-prone.

media: rockchip: rkisp1: extend uapi array sizes

2021-01-28T10:31:43Z

Later variants of the rkisp1 block use more entries in some arrays: RKISP1_CIF_ISP_AE_MEAN_MAX 25 -> 81 RKISP1_CIF_ISP_HIST_BIN_N_MAX 16 -> 32 RKISP1_CIF_ISP_GAMMA_OUT_MAX_SAMPLES 17 -> 34 RKISP1_CIF_ISP_HISTOGRAM_WEIGHT_GRIDS_SIZE 25 -> 81 and we can still extend the uapi during the 5.11-rc cycle, so do that now to be on the safe side. V10 and V11 only need the smaller sizes, while V12 and V13 needed the larger sizes. When adding the bigger sizes make sure, values filled from hardware values and transmitted to userspace don't leak kernel data by zeroing them beforehand.

media: rockchip: rkisp1: carry ip version information

2021-01-28T10:31:08Z

The IP block evolved from its rk3288/rk3399 base and the vendor designates them with a numerical version. rk3399 for example is designated V10 probably meaning V1.0. 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 [fix checkpatch warning don't use multiple blank lines] Signed-off-by: Heiko Stuebner Signed-off-by: Dafna Hirschfeld Reviewed-by: Ezequiel Garcia Acked-by: Helen Koike Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

2021-01-28T10:30:39Z

The uapi right now specifies an array size of 28 but the actual number of elements is only 25 with the last 3 being unused. Reduce the array size to the correct number of elements and change the params code to iterate the array 25 times.
