Fixes several alignment, braces, space-before-cast, camelcase et al issues reported by checkpatch --strict, plus a few more checkpatch didn't report. Three checks are left after this though: - one CamelCase in ddbridge-core, related to defines/vars/enums referenced from the stv090x demod driver - one macro argument reuse in ddbridge-core aswell - one unbalanced braces around else in ddbridge-main, which is due to #ifdefs related to CONFIG_PCI_MSI, which preferrably should be kept as-is for readability.

A 0b1100 value in 4 LSBs of "General Status 1" register (AFD_FMT_STAT) has known meaning for CX2584x-series chips - it means that a SECAM signal is currently detected by the chip. Use this opportunity to also fix wrong binary values that were present as comments attached to some entries in an array where chip register -> V4L2 standard mappings are stored. Signed-off-by:

The complete handler walks all entities, expecting to find an imx subdevice for each and every entity. However, camera drivers such as smiapp can themselves contain multiple entities, for which there will not be an imx subdevice. This causes imx_media_find_subdev_by_sd() to fail, making the imx capture system unusable with such cameras. Work around this by killing the error entirely, thereby allowing the imx capture to be used with such cameras. Signed-off-by:

As we're now using SPDX identifiers, add the proper SPDX, better identifying the licenses whith apply to the source code. As we're now using the short license, it doesn't make sense to keep the original license text. Also, fix MODULE_LICENSE to properly identify GPL v2 at the Siano's common driver. Some codes there are licensed on GPL v2 or latter, while others are GPL v2 only. So, in order to reflect the common license that applies to everything, the module itself should be GPLv2 only. While here, use the Kernel's coding style for the comments with copyright info. Signed-off-by: -

timespec is generally deprecated because of the y2038 overflow. In vivid, the usage is fine, since we are dealing with monotonic timestamps, but we can also simplify the code by going to ktime_t. Using ktime_divns() should be roughly as efficient as the old code, since the constant 64-bit division gets turned into a multiplication on modern platforms, and we save multiple 32-bit divisions that can be expensive e.g. on ARMv7.

The imx media driver passes around monotonic timestamps in the deprecated 'timespec' format. This is not a problem for the driver, as they won't overflow, but moving to either timespec64 or ktime_t is preferred. I'm picking ktime_t for simplicity here. frame_interval_monitor() is the main function that changes, as it tries to compare a time interval in microseconds. The algorithm slightly changes here, to avoid 64-bit division. The code previously assumed that the error was at most 32-bit worth of microseconds here, so I'm making the same assumption but add an explicit test for it. Signed-off-by:

solo6x10 correctly deals with time stamps and will never suffer from overflows, but it uses the deprecated 'struct timespec' type and 'ktime_get_ts()' interface to read the monotonic clock. This changes it to use ktime_get_ts64() instead, so we can eventually remove ktime_get_ts(). Signed-off-by:

H264 entropy mode can be selected via V4L2 API but is eventually not applied. Configure encoder with selected mode, CALVC (def) or CABAC. Note that hw/firmware also expects a CABAC model configuration which currently doesn't have existing V4L2 API control. For now, use model_0 which seems always supported and so the default one.

There is no need to #define the license of the driver, just put it in the MODULE_LICENSE() line directly as a text string. This allows tools that check that the module license matches the source code license to work properly, as there is no need to unwind the unneeded dereference.
