Group the CAMERARX functions together to make the overall driver structure easier to navigate. This only moves functions around, no functional change is included. Signed-off-by:

Rename all functions related to CAMERARX with a cal_camerarx_ prefix, and pass them a cal_camerarx pointer. This performs most of the decoupling of the CAMERARX from the context. Signed-off-by:

The sensor is connected to the CAMERARX. Store its pointer, as well as the sensor pixel rate and the endpoint, in the cal_camerarx. This prepares for decoupling the cal_camerarx and cal_ctx. Signed-off-by:

Prepare for passing the cal_camerarx pointer instead of the cal_ctx pointer to CAMERARX-related functions by adding print macros for cal_camerarx. Signed-off-by:

Laurent Pinchart authored
Use the dev_* print macros instead of the v4l2_* print macros. This prepares for a common print infrastructure that will also support the cal_camerarx instances. Signed-off-by:

Store a pointer to the cal_dev and the cal_camerarx instance number in the cal_camerarx structure. This prepares for passing a cal_camerarx pointer instead of a cal_ctx pointer to multiple functions that deal with the CAMERARX. Signed-off-by:

The cal_camerarx structure describes the PHY, there's no need for an internal structure named phy. Removed that level of indirection. Signed-off-by:

Laurent Pinchart authored
Name all variables that point to a cal_camerax instance 'phy' instead of 'cc'. The name 'cc' refers to Camera Core, but is not commonly used in the driver or in datasheets. Signed-off-by:
-
Laurent Pinchart authored
Name all variables pointing to a cal_dev instance 'cal', instead of a combination of 'caldev' and 'dev'. 'caldev' is only used in a few places and could have been renamed to 'dev', but 'dev' is confusing as it's also used for struct device instances. This generates lots of changes, but increases readability. Signed-off-by:

The cal_csi2_phy contains platform data for the CAMERARX blocks. Rename it to cal_camerarx_data. Signed-off-by:
-
Laurent Pinchart authored
The various data structures that describe the components of the camera access layer (CAL) are named without much consistency. Start cleaning this up by renaming the structure that describes the CAMERARX block, cc_data, to cal_camerarx. Signed-off-by:

Move the csi2_phy_config() function to avoid its forward declaration. No functional change is included. Signed-off-by:

The cal_dev flags field is a copy of data->flags. Use the latter and remove the former. Signed-off-by:

Remove structure fields that are never set, set and never read, or set to a fixed value. This allows removal of a global variable and a macro. Signed-off-by:
-
Laurent Pinchart authored
The global static const cal_regmap_config template is only used in a single location, to initialize 3 fields of a local variable. Two of those fields then get overwritten. Remove the template and set the last remaining field manually. Simplify the code by hardcoding the field values instead of calculating them for a variable that always has the same value.

Now that no platform data fields are modified at runtime, make the corresponding structures const. The const qualifier for integer fields is removed as it's not required anymore. Signed-off-by:
-
Laurent Pinchart authored
Several structure fields declared as int store positive values only. Make them unsigned. Signed-off-by:
-
Laurent Pinchart authored
The cal_csi2_phy structure has lost its 'fields' field that used to clash with the 'base_fields' field. Rename base_fields to fields. Signed-off-by:
-
Laurent Pinchart authored
The PHY regmap fields are created dynamically at runtime. They don't belong to the platform data that should be constant. Move them to the cc_data structure. Signed-off-by:
-
Laurent Pinchart authored
In preparation to constify cal_csi2_phy, avoid modifying the base_fields array at runtime. As the array now only needs to stored two values instead of a full struct reg_field instance, save memory by using a custom structure for the base_fields elements. Signed-off-by:
-
Laurent Pinchart authored
The base_fields field of cal_csi2_phy points to a fixed-size array of struct reg_field. This level of indirection isn't needed, embed the array directly in struct cal_csi2_phy. Signed-off-by:

Many loop indices only take positive values. Make them unsigned. Signed-off-by:

Casting from a void pointer to a struct pointer doesn't require a cast. Remove them. Signed-off-by:

A few local variables are needlessly initialized. Fix them. Signed-off-by:

The static cal_formats array contains const data, make it const. This requires turning a few cal_fmt pointers into const pointers. Signed-off-by:
-
Laurent Pinchart authored
Turn the reg_(read|write)_field() macros into inline functions for additional type safety. Use the FIELD_GET() and FIELD_PREP() macros internally instead of reinventing the wheel. Signed-off-by:
-
Laurent Pinchart authored
The CAL_VERSION macro is used once only, in MODULE_VERSION(). This doesn't improve readability, inline it. Signed-off-by:

Laurent Pinchart authored
The cal_irq() function reads three IRQ status registers and stores their values in three different variables. As each value is processed right after reading the corresponding register, a single variable is enough. Signed-off-by:
-
Laurent Pinchart authored
The datasheet numbers the IRQ registers starting from 0. Update the numbering scheme to match the datasheet. Signed-off-by:
-
Laurent Pinchart authored
The datasheet numbers the CSI-2 PHYs (external to the CAL) starting from 1, but the PPI inputs to the CAL starting from 0. Update the numbering scheme for csi2_port to match the datasheet, which also simplifies the driver by removing the need to constantly subtract 1 from the value. Signed-off-by:

Laurent Pinchart authored
The CPORT mentioned in the CAL documentation has nothing to do with the CSI-2 ports. It's a remnant of CSI-3 support (or an attempt to achieve it), and now only serves as an arbitraty tag value used to associate data samples with contexts. Add a cport field to the cal_ctx structure and use it instead of the CSI-2 port number where a CPORT is required by the hardware. The value of the cport field is currently the same as the csi2_port field, so there's no functional change, but this will help reworking CPORT and CSI-2 port handling separately. Signed-off-by:

Move the cal_complete_ctx() function earlier in the file to avoid a foward declaration. There is no functional change. Signed-off-by:

If a device supports a resolution in 2 different formats, mode[0] is skipped on first iteration and a different format is selected. Example: 320x240/YUYV isn't reachable for OV534/ov772x Signed-off-by:

Memory allocated with 'v4l2_m2m_init()' must be freed by a corresponding call to 'v4l2_m2m_release()' Also reorder the code at the end of the probe function so that 'video_register_device()' is called last. Update the error handling path accordingly. Fixes: 5ce60d79 ("[media] s5p-g2d: Add DT based discovery support") Fixes: 91884734 ("[media] v4l: add G2D driver for s5p device family") Signed-off-by:

It's all too easy to get confused by the V4L2_TYPE_IS_OUTPUT macro, when it's used as !V4L2_TYPE_IS_OUTPUT. Reduce the risk of confusion with macro to explicitly check for the CAPTURE queue type case. This change does not affect functionality, and it's only intended to make the code more readable.
