For historical reasons, stateful codec controls are named as {}_MPEG_{}. While we can't at this point sanely change all control IDs (such as V4L2_CID_MPEG_VIDEO_VP8_FRAME_HEADER), we can least change the more meaningful macros such as classes macros.

Cedrus supports H.264 profiles from Baseline to High, except for the Extended profile Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE so that userspace can query the driver for the supported profiles and levels. Signed-off-by:

The Rockchip Video Decoder used in RK3399 supports H.264 profiles from Baseline to High 4:2:2 up to Level 5.1, except for the Extended profile. Expose the V4L2_CID_MPEG_VIDEO_H264_PROFILE and the V4L2_CID_MPEG_VIDEO_H264_LEVEL control, so that userspace can query the driver for the list of supported profiles and level. For now, we don't expose 4:2:2 since the driver doesn't implement the required support. [Ezequiel: Don't expose 4:2:2 profile for now] Signed-off-by:

Add a debug message for control validation (validate_new) failures. This is useful to debug issues with ioctls such as VIDIOC_TRY_EXT_CTRLS and VIDIOC_S_EXT_CTRLS. Signed-off-by:

V4L2_CTRL_CLASS_DETECT was never documented here, add it. Signed-off-by:

The VP8_FRAME_HEADER control type is validated, so it needs a corresponding initialization to produce default legal values. For now, only add the minimum required initialization to satisfy current validation. Signed-off-by:

Use regulators vio and vcore besides vana. The regulators were always there but on many boards they've been hard wired. Control them explicitly now. Signed-off-by:

Vcore and vio supplies are also part of the spec and used by many sensors. Do not specify the voltages as they are generally sensor dependent. Signed-off-by:

It was mentioned vana voltage is typically 2,8 volts. This is truly sensor dependent, and nowadays 2,8 volts is a lot. Signed-off-by:

Over the years (and renaming) some lines that may well be wrapped ended up being over 80 characters, likewise there are shorter lines that can be merged. Do that. Signed-off-by:

If pm_runtime_get_sync() fails, there's no need to set the device active again. Also, in the same case to return the usage_count to zero, pm_runtime_put_noidle() is enough. Signed-off-by:

Make the delay between I²C access retries a range between 1 and 2 ms. Also make the number of retries 10 instead of 5, in order not to reduce the total amount of time. Signed-off-by:

MIPI CCS replaces SMIA and SMIA++ as the current standard. CCS brings new features while existing functionality will be supported. Rename the smiapp-pll as ccs-pll accordingly. Also add Intel copyright to the files. Signed-off-by:

Some limit values are available in q16.q16 format, referred to as 32-bit unsigned ireal in CCS. Read these correctly. Signed-off-by:
-
Sakari Ailus authored
Instead of converting the limit values at register read time, do that at access time instead. Signed-off-by:
-
Sakari Ailus authored
The limit values will be raw soon, and the conversion takes place later on. Prepare for that. Signed-off-by:

Rework quirk and 8-bit only access functions with a single function that takes arguments. This is later extensible to support yet more flags. Signed-off-by:

If an internal driver error was encountered, BUG was issued. Instead, do less harsh WARN_ON_ONCE and try to manage with the consequences. Signed-off-by:

The NULL check is not needed as the functions do not return NULL. Remove the check (and BUG). Signed-off-by:

The register arrays have a certain size but not all the entries will be relevant. In practice reading can be stopped after encountering a zero value in the array. Do that to avoid extra reads. Signed-off-by:

The module revision number major and minor are both 8 bits while the sensor revision number is 16 bits. Combine the module revision into one number. This also adds printing the lowest 8 bits of the module version through the sysfs attribute. Signed-off-by:

Add a parser library for parsing the CCS static data format. The library may be also compiled in user space as the format has uses also in the user space. Therefore it is dual licensed under the 3-clause BSD license as well. Signed-off-by:

Sakari Ailus authored
Let v4l2_fwnode_endpoint_alloc_parse to figure out the type of the data bus. As the old bindings did not require the "bus-type" property, we need to rely on guessing between CSI-2 D-PHY and CCP2. Setting the type to CSI-2 D-PHY will parse just that and succeed even if no data-lanes are set. Also add a comment on the matter to the driver to avoid breaking this in the future. Signed-off-by:

As documentation used to be in .txt files before converting to ReST, rename ccs-regs.txt to avoid it being taken as documentation that pre-dates ReST conversion and so target for further conversion to ReST. Signed-off-by:

The debugfs_create_dir() function never returns NULLs so this code will never be executed. It's not intended that callers will check for debugfs errors in the normal case and it's not necessary in this driver, so we can just delete this code. Signed-off-by:
