Gstreamer's v4l2src reacted poorly to certain outputs from the bcm2835 video driver's ioctl ops function vidioc_enum_framesizes, so a workaround was created that could be activated by user input. This workaround would replace the driver's ioctl ops struct with another, similar struct--only with no function pointed to by vidioc_enum_framesizes. With no response, gstreamer would attempt to continue with some default settings that happened to work better. However, this bug has been fixed in gstreamer since 2014, so we shouldn't include this workaround in the stable version of the driver. Signed-off-by:

Driver SDIO code uses helper functions to do IO to the SDIO device. Current helpers handle IO of a single byte as well as multi-byte. Driver predominately uses single byte IO. If the common case is made simple it simplifies the whole driver. The common case can be made simple by splitting the multi-byte and single byte calls into separate functions, i.e 4 functions in total, read single byte, read multi-byte, write single byte, write multi-byte. Also, we need to handle the debug code. Currently debug calls after read/write fail access the IO buffer. This buffer, at best, does not hold useful data on the error path, at worst is uninitialized and holds garbage. Split read/write helper functions into two functions each, one for single byte IO and one for multi-byte IO. Fix all call sites. Do not change the program logic. Signed-off-by:

Currently driver uses a hardware information struct description to group some SDIO related functionality (work, work queue, sdio private data pointer). This structure is then embedded in the device private data structure. Having nested structures described in different header files means that to view the device private data programmers must open two header files. This structure could be embedded anonymously in the device private data and achieve the same result (grouping of function specific to SDIO) without the need to open multiple headers. However, the SDIO private data structure already has various different data and pointers, adding the embedded structure adds little extra meaning and lengthens all the dereferences throughout the driver, often meaning addition line breaks and braces. We can increase readability and reduce code complexity by moving the hardware information data and pointers to directly be within the device private data structure description. While preparing for this refactoring it was noted that the identifier currently used for the delayed work is 'rw_wq', this is confusing since the 'wq' suffix typically means 'work queue'. This identifier would be more meaningful if it used the suffix 'dwork' as does the declaration of queue_delayed_work() (include/linux/workqueue.h). The identifier for the work queue is currently 'ks7010sdio_wq'. This identifier can be shortened without loss of meaning because there is only one work queue within the driver. Identifier 'wq' is typical within in-tree driver code and aptly describes the pointer. Current pointer to the SDIO private data is identified by 'sdio_card', this is sufficiently meaningful from within the hw_info structure but once the hw_info_t structure is removed the pointer would be better to have a prefix appended to it to retain the prior level of meaning. Move members from struct hw_info_t to struct ks_wlan_private. Rename identifiers; struct delayed_work pointer 'rw_wq' to 'rw_dwork'. struct workqueue_struct pointer 'ks7010sdio_wq' to 'wq'. struct ks_sdio_card pointer 'sdio_card' to 'ks_sdio_card'. Remove structure description hw_info_t. Fix init/destroy calls. Fix all call sites, SDIO private data access calls, and queuing calls. Signed-off-by:

Currently a pointer to the tasklet_struct used for bottom half processing on the receive path is within the hw_info_t structure. This structure is then embedded in the device private data structure. Having the tasklet_struct nested does not add meaning to the device private data, device private data already (and typically) has various data relating to the device, there is no real need to separate the tasklet_struct to a SDIO specific structure. While not adding allot of extra meaning having the nested structure means the programmer must open two header files to read the description of the device private data, the code would be easier to read if the device private data struct description was not spread over two files. Move tasklet_struct out of sdio header file and into the device private data structure description. Signed-off-by:

struct work_struct uses identifier ks_wlan_wakeup_task, this is confusing because the 'task' suffix implies that this is a tasklet_struct instead of a work struct. Suffix 'work' would be more clear. The code would be easier to read if it followed the principle of least surprise and used the 'work' suffix for a work_struct identifier. Rename work_struct structure 'ks_wlan_wakeup_task' to 'wakeup_work'. Signed-off-by:

complete_handler() takes void * types as parameters. void * parameters are then cast to struct types. Call sites for this function either pass in NULL or pointers to the struct types cast to void *. This casting is unnecessary and can be removed. Struct tx_device_buffer (which contains a pointer member to the complete_handler() function) has as member 'ks_wlan_priv *priv' this is unnecessary, we always have a pointer to this struct there is no need to store it here. The complete_handler can be more clearly defined by using struct pointer types instead of void * types. The code is currently unnecessarily complex, storing and passing extraneous pointer parameters. Remove unnecessary parameters, unnecessary casting to/from 'void *'. Fix all call sites involving complete_handler(). Signed-off-by:

Header has multiple constants defined using preprocessor directive. In the cases where these are an integer progression an enumeration type can be used. Doing so adds documentation to the code and makes the usage explicit. Maintain original constant value, this value is returned by the device.

SDIO header currently defines unused constants READ_STATUS_BUSY and WRITE_STATUS_IDLE. There are reciprocal constants that are used READ_STATUS_IDLE and WRITE_STATUS_BUSY. We can roll these into a single enumeration type and remove the two that are unused. Add enumeration type containing IDLE/BUSY pair that are currently used within the SDIO source. Change source to use new enum types. Signed-off-by:

The Makefile / Kconfig currently controlling compilation of this code is: clock/Makefile:obj-$(CONFIG_INTEL_ATOMISP) += vlv2_plat_clock.o atomisp/Kconfig:menuconfig INTEL_ATOMISP atomisp/Kconfig: bool "Enable support to Intel MIPI camera drivers" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. Since module_init was already not in use by this driver, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
