Rework the CSI-2 firmware parsing code to not use the soon to be removed v4l2_async_notifier_parse_fwnode_endpoints_by_port() helper. The change only aims to prepare for the removing of the old helper and there are no functional change. Signed-off-by:

In preparation of removing the usage of the old helper v4l2_async_notifier_parse_fwnode_endpoints_by_port() use the v4l2_async_subdev instead of fwnode_handle to match subdevices. Signed-off-by:

In preparation of removing the usage of the old helper v4l2_async_notifier_parse_fwnode_endpoints_by_port() do not dynamically allocate the whole structure containing the parameters for the parallel interface, instead only allocate the v4l2_async_subdev structure. There is no functional change. Signed-off-by:

Currently pointer nvm is being dereferenced before it is being null checked. Fix this by moving the assignments of pointers client and ov2740 so that are after the null check hence avoiding any potential null pointer dereferences on pointer nvm.

The subdev's video device node was only assigned after registering the device node in the system. While it is unlikely that a driver needed to use this field in handling system calls to its file handle, there remains a slim chance the devnode field remains NULL while the driver expects to find a video node there. Assign the devnode field before registering the device, and assign it back to NULL if the registration failed. Signed-off-by:

in_interrupt() covers hard and soft interrupt servicing and bottom half disabled contexts, which is semantically undefined and useless. The comment for __ccdc_lsc_configure() "Context: in_interrupt()" is therefore as useful as "Context: unknown'. Remove it. Signed-off-by:

The DT bindings documented "reset-gpios" property but the driver never made use of it. Instead it used a GPIO called "xshutdown", with apprently wrong polarity. Fix this by requesting "reset" GPIO with the right polarity first, and if that fails, then request "xshutdown" GPIO with the old polarity. This way it works for new users as expected while if someone, somewhere, depended on "xshutdown" GPIO, that continues to work as well. Signed-off-by:

The bus-type property is required for C-PHY support. Add it, including values for CCP2 and CSI-2 D-PHY. Also require the bus-type property. Effectively all new sensors are MIPI D-PHY or C-PHY that cannot be told apart without the bus-type property. Signed-off-by:

Amend the existing SMIA bindings by adding MIPI CCS support, with separate compatible strings for CCS 1.0 and CCS 1.1. Rename the old bindings accordingly as CCS is the current standard. Signed-off-by:

Generally reset signal is active low on camera sensors. The example had it high. Make it low, and use GPIO_ACTIVE_LOW in gpio.h for that. Signed-off-by:

Rename the "smiapp" driver as "ccs". MIPI CCS is the contemporary standard for raw Bayer camera sensors. The driver retains support for the SMIA++ and SMIA compliant camera sensors. A module alias is added for old user space using "smiapp" module name. Add Intel copyright while at it. Signed-off-by:

Call CCS compliant sensors as "ccs" instead of "smiapp" in absence of a device specific name. This is done based on the value of the manufacturer ID register that is only present in CCS. Signed-off-by:

Sakari Ailus authored
Add register definitions of the MIPI CCS 1.1 standard. The CCS driver makes extended use of device's capability registers that are dependent on CCS version. This involves having an in-memory data structure for limit and capability information, creating that data structure and accessing it. The register definitions as well as the definitions of this data structure are generated from a text file using a Perl script. Add the generator script to make it easy to update the generated files.
