The MAX9271 GPIO1 line that controls the sensor reset is by default enabled after a serializer chip reset. As rdacm20 does not go through an explicit serializer reset, make sure GPIO1 is enabled to make the camera module driver more robust. Fixes: 34009bff ("media: i2c: Add RDACM20 driver") Signed-off-by:

Fix GPIO enable/disable operations which wrongly read the 0x0f register to obtain the current mask of the enabled lines instead of using the correct 0x0e register. Also fix access to bit 0 of the register which is marked as reserved. Fixes: 34009bff ("media: i2c: Add RDACM20 driver") Signed-off-by:

There are no users left of this helper and as it implements an undesirable and too simple behaviour that should instead be implemented directly by drivers remove it to prevent future uses of it. Suggested-by:

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() 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:

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:
