I don't know what minimal image dimensions are, but 32x32 appears to be ok according to the docs. This is needed for small sensors like 80x80 thermal imagers. Signed-off-by:

Currently there is no method to know the correct order of the colors for a test image generated by tpg. Write a function that returns a string of colors' order given a tpg. It returns a NULL pointer in case of test patterns which do not have a well defined colors' order. Hence add a NULL check for text in tpg_gen_text().

Change the argument of type char * to const char * for function tpg_gen_text(). This function should take in a const char * as opposed to char * as it does not make changes to the text. This issue was found while passing the order of colors of tpg generated test image (which is a const char *) to this function. Signed-off-by:

If platform_driver_register() fails within vpss_init() resources are not cleaned up. The patch fixes this issue by introducing the corresponding error handling. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

The hardware only supports 4:2:0 or 4:0:0 (monochrome), 8-bit depth content. Verify that the SPS refers to a supported bitstream, and refuse unsupported bitstreams by failing at TRY_EXT_CTRLS time. Given the JPEG compression level control is the only one that needs setting, a specific ops is provided. Signed-off-by:

The hardware only supports 4:2:2, 4:2:0 or 4:0:0 (monochrome), 8-bit or 10-bit depth content. Verify that the SPS refers to a supported bitstream, and refuse unsupported bitstreams by failing at TRY_EXT_CTRLS time. The driver is currently broken on 10-bit and 4:2:2 so disallow those as well.

Commit 986eee3a ("media: hantro: Prevent encoders from using post-processing") fixed hantro_needs_postproc condition, but missed one case. Encoders don't have any post-processor hardware block, so also can't be disabled. Fix it. Fixes: 986eee3a ("media: hantro: Prevent encoders from using post-processing") Signed-off-by:

The driver doesn't need the bytesused argument. For decoders, the plane bytesused is known and therefore, buf_prepare is used to set it. For encoders, it's handled by the codec_ops.done hook. Signed-off-by:
-
Ezequiel Garcia authored
hantro_enc_buf_finish is used only for JPEG, and so should be moved to JPEG codec_ops.done. This cleanup is also taking care of addressing a subtle issue: checking the non-NULL bounce buffer using ctx->jpeg_enc, which is a member of a union is confusing and error-prone. Note that the issue is currently innocuous because an encoder context only supports JPEG. The codec_ops.done has an argument that codec-specific code shouldn't need, so drop that as well.

So far we've been using the .buf_finish hook to distinguish decoder from encoder. This is unnecessarily obfuscated. Moreover, we want to move the buf_finish, so use a cleaner scheme to distinguish the driver decoder/encoder type. Signed-off-by:

Commit e17f08e3 ("media: hantro: Do not reorder H264 scaling list") removed the scaling list reordering, which was wrong and not needed. However, the name of the function stayed, which is confusing for anyone reading the code. Rename from "reorder" to "assemble" which is cleaner. This is just a cosmetic cleanup. Signed-off-by:

Currently the stats are read in a work queue. Defering the reading of the stats is not needed and it is fine to read them inside the irq handler. This patch fixes and remove the TODO item: 'Use threaded interrupt for rkisp1_stats_isr(), remove work queue.' Signed-off-by:

Dafna Hirschfeld authored
This patch removes two locks in the rkisp1_stats struct: - The mutex 'wq_lock' that is used to protect the buffers list 'stat' - The spin_lock 'irq_lock' that is used to protect the variable 'is_streaming' It replaces them with one spin_lock 'lock' that protects both the buffers list and the 'is_streaming' variable. In later patch the reading of the statistics will move to the isr so there will be no need for the mutex 'wq_lock' Signed-off-by:

Implementation of media controller centric device configuration will add code to the CAMERARX support section, which is already quite big. Move it to a separate file to make the code more manageable. No functional change is included. The cal_camerarx_init_regmap() function is kept in cal.c and renamed to cal_init_camerarx_regmap() as it's not specific to one CAMERARX instance, but related to the whole CAL device. Signed-off-by:

To prepare for the split of the camerarx code to a separate file, move the CAL I/O accessors to cal.h. This requires renaming the accessors with a cal_prefix, as the current names are too generic and prone to namespace clashes. The reg_read() and read_write() macros, that cover both CAL and CAMERARX register access, are split in two groups of inline functions, one for CAL access and one for CAMERARX access. Signed-off-by:

The phy->sensor NULL check in cal_camerarx_get_external_rate() is not needed, as the V4L2 video devices are only registered when the sensor is bound. Remove it. Signed-off-by:

Laurent Pinchart authored
The external pixel rate is retrieved when starting the camerarx and only used then. There's no need to store it in the cal_camerarx structure, it can be returned by cal_camerarx_get_external_info() and explicitly passed to cal_camerarx_config(). While at it, rename cal_camerarx_get_external_info() to cal_camerarx_get_external_rate() to better reflect the function's purpose. Signed-off-by:

Refactor the camerarx start and stop procedure to group all the corresponding operations in two functions, cal_camerarx_start() and cal_camerarx_stop() instead of splitting them in multiple steps called from the vb2 stream start and stop functions. This reduces the coupling between the camerarx and the contexts, and better models the camerarx hardware. The cal_camerarx_start() is a reworked version of cal_camerarx_init() with the description of the start procedure updated to match the AM65x, DRA7[124567]x and DRA80xM TRMs. The cal_camerarx_wait_ready() function is inlined in cal_camerarx_start() to better describe the start procedure. No functional change is included in the camerarx start and stop procedures themselves, but the interleaving of the start steps with the context configuration has been changed in cal_start_streaming().

Create four functions to handle initialization, cleanup, registration and unregistration of the V4L2 (and soon media controller) objects: - init() is meant to be called early at probe time to initialize the objects, before they get used from within the kernel - cleanup() is the counterpart of init, and is meant to be called at the end of the remove sequence to free all objects - register() is meant to be called at the end of the probe sequence, to register the userspace-facing devices - unregister() is the counterpart of register, and is meant to be called at the beginning for the remove sequence, to disallow access from userspace Signed-off-by:
