The OTP data was not ready after registered as nvmem device, it is risky as the nvmem read may happen once the device exists, this patch get the OTP data ready before registering the nvmem device. OTP data missing should not break the normal camera sensor probe, so use a warning instead of an error message. Signed-off-by:

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Signed-off-by:

The parallel port nodes should be numbered 1 and 2, not 0 and 1 for A and B respectively. The driver has always implemented 1 and 2 and the in-tree Goni DTS uses 1 as port A as well. Update the documentation to match this behaviour. Signed-off-by:

vidioc_streamoff can be called multiple times from userspace, but we should only call media_pipeline_stop when we're actually setup. This became more noticeable after commit 2a2599c6 ("[media] media: entity: Catch unbalanced media_pipeline_stop calls") was merged as it added a WARN for unbalanced calls to media_pipeline_stop.

On some devices, there may be multiple camera sensors attached to the same port. Make sure we probe all of them, not just the first one. Signed-off-by:
-
Jonathan Bakker authored
Instead of keeping a local copy of how many sensors we've probed (which may not even properly represent the number of sensors probed if we have a port without a sensor), use the global num_sensors counter that has the actual number used. This will also make it easier to add support for multiple sensors being connected to the same port. Signed-off-by:

Commit bae45003 ("[media] exynos4-is: Add missing entity function initialization") tried to suppress the warnings such as s5p-fimc-md camera: Entity type for entity FIMC.0 was not initialized! However, this missed setting for the subdev. Set it now to avoid the ugly warnings on boot. Signed-off-by:

Not all devices use the CSIS device, some may use the FIMC directly in which case the CSIS device isn't registered. This leads to a nullptr exception when starting the stream as the CSIS device is always referenced. Instead, if getting the CSIS device fails, try getting the FIMC directly to check if we are using the subdev API Signed-off-by:

On FIMC variants which don't have writeback channel, there is no need to access system registers. This patch makes the driver request sysreg regmap conditionally depending on whether writeback is supported. Signed-off-by:

When the post-processor is enabled, the driver allocates "shadow buffers" which are used for the decoder core, and exposes the post-processed buffers to userspace. For this reason, extra motion vector space has to be allocated on the shadow buffers, which the driver wasn't doing. Fix it. This fix should address artifacts on high profile bitstreams.

If the bitstream and the application are incorrectly configuring the reference pictures, the hardware will need to fallback to using some other reference picture. When the post-processor is enabled, the fallback buffer should be a shadow buffer (postproc.dec_q), and not a CAPTURE queue buffer, since the latter is post-processed and not really the output of the decoder core.

list_for_each_entry is able to handle an empty list. The only effect of avoiding the loop is not initializing the index variable. Drop list_empty tests in cases where these variables are not used. Note that list_for_each_entry is defined in terms of list_first_entry, which indicates that it should not be used on an empty list. But in list_for_each_entry, the element obtained by list_first_entry is not really accessed, only the address of its list_head field is compared to the address of the list head, so the list_first_entry is safe. The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) <smpl> @@ expression x,e; iterator name list_for_each_entry; statement S; identifier i; @@ -if (!(list_empty(x))) { list_for_each_entry(i,x,...)

In the irq handler 'rkisp1_params_isr', the lock 'config_lock' should be held as long as the current buffer is used. Otherwise the stop_streaming calback might remove it from the list and pass it to userspace while it is referenced in the irq handler. Signed-off-by:

The two macros RKISP1_CIF_ISP_LSC_{GRAD/SIZE}_TBL_SIZE have the same value which is the number of sectors in the grads and size parameters. Therefore there is no need for two different macros. Replace them with one macro RKISP1_CIF_ISP_LSC_SECTORS_TBL_SIZE. Also use the macro when iterating the arrays instead of hardcoded '4'. Signed-off-by: -

Currently the fields '*_data_tbl' in the struct 'rkisp1_cif_isp_lsc_config' are one dimensional arrays of size 290. The entries are accessed in a nested loop by summing two indexes for the rows and columns. Therefore it fits better to define the arrays as two dimensional arrays of size 17x17. Signed-off-by:
