Ask device connected on sink pad for link frequency in order to configure CLK_LANE_REG1 (ui_x4). If not available, ask for pixel rate information to compute it. This is needed to deal with compressed format such as JPEG where number of bits per pixel is unknown: computation of link frequency from pixel rate is not possible. Signed-off-by:

The sensor needs the MCLK clock running when it's being probed. On platforms where the sensor is instantiated from a DT (MMP2) it is going to happen asynchronously. Therefore, the current modus operandi, where the bridge driver fiddles with the sensor power and clock itself is not going to fly. As the comments wisely note, this doesn't even belong there. Luckily, the ov7670 driver is already able to control its power and reset lines, we can just drop the MMP platform glue altogether. It also requests the clock via the standard clock subsystem. Good -- let's set up a clock instance so that the sensor can ask us to enable the clock. Note that this is pretty dumb at the moment: the clock is hardwired to a particular frequency and parent. It was always the case. Signed-off-by:

An instance of a sensor on DT-based MMP2 platform is always going to be created asynchronously. Let's move the manual device creation away from the core to the Cafe driver (used on OLPC XO-1, not present in DT) and set up appropriate async matches: I2C on Cafe, FWNODE on MMP (OLPC XO-1.75).

Use the names more suitable for devicetree bindings. There are no board files utilizing this, thus we seem to be at liberty at renaming this without consequences. Signed-off-by:

This accesses the clock registers directly and thus is going to stay in the way of making the driver devicetree friendly. No boards seems to actually use this. If it's somehow actually needed it needs to be done differently. This reverts commit 7c269f45. Signed-off-by:

In the patch refactoring the fw-node, the mt9m111 was broken for all platform_data based platforms, which were the first aim of this driver. Only the devicetree platform are still functional, probably because the testing was done on these. The result is that -EINVAL is systematically return for such platforms, what this patch fixes.

In the soc_camera removal, the board specific power callback was dropped. This at least will remove the power optimization from ezx and em-x270 pxa based boards. As to recreate the same level of functionality, make the mt9m111 have a regulator providing it its power, so that board designers can plug in a gpio based or ldo regulator, mimicking their former soc_camera power hook.

devm_gpiod_get never returns NULL; therefore it's not necessary to check for that. PTR_ERR(NULL) also yields zero, which is confusing to smatch. Reported-by:

PTR_ERR(NULL) yields 0 which is commonly used to denote success. This is the case here, and PTR_ERR(NULL) is apparently shunned upon. Fix this by explicitly returning 0 if fwnode == NULL. Reported-by:

Commit c62b9605 ("media: ov6650: Register with asynchronous subdevice framework") carelessly requested creation of a video device node by setting a V4L2_SUBDEV_FL_HAS_DEVNODE flag. The driver is not ready for that as it doesn't implement proper locking required for serialization of IOCTLs. Fix it by dropping the flag assignment.

CEC adapters and controllers (handlers) are now set up as follows: 1. Allocate CEC adapters: setup of control handlers in next step requires these adapters to be allocated. 2. Setup of control handlers: This must be done prior to registering and exposing the adapters to user space to avoid a race condition. 3. Register CEC adapters: make them available to user space.

The __packed macro isn't available in userspace with the kernel headers. Checkpatch asks to use the macro, which is unwanted in a case of a UAPI header. There is no much benefit in a tight packing of the structures, hence let's pack them manually to cleanup things a tad. Note that there is no old-stable userspace that will suffer from this change, hence it's fine to change the ABI. In a result also more space is reserved for a possible future expansion of the UAPI as it was already shown that more fields will be needed for a later SoC generations. Suggested-by:

AST2500 silicon revision A1 and A2 have a silicon bug which causes extremly long capturing time on specific resolutions (1680 width). To fix the bug, this commit adjusts the capturing window register setting to 1728 if detected width is 1680. The compression window register setting will be kept as the original width so output result will be the same. Signed-off-by:
