Structures that have a single element array as the last field can be mistaken as a "flex array". We could replace all the single element arrays in the structure with single element fields, but this driver prefers to follow the ITU-T H.265 specification, which defines it as an array.

2024-05-23tracing/treewide: Remove second parameter of __assign_str()Steven Rostedt (Google)1-1/+1
With the rework of how the __string() handles dynamic strings where it saves off the source string in field in the helper structure[1], the assignment of that value to the trace event field is stored in the helper value and does not need to be passed in again. This means that with: __string(field, mystring) Which use to be assigned with __assign_str(field, mystring), no longer needs the second parameter and it is unused. With this, __assign_str() will now only get a single parameter. There's over 700 users of __assign_str() and because coccinelle does not handle the TRACE_EVENT() macro I ended up using the following sed script: git grep -l __assign_str | while read a ; do sed -e 's/\(__assign_str([^,]*[^ ,]\) *,[^;]*/\1)/' $a > /tmp/test-file; mv /tmp/test-file $a; done I then searched for __assign_str() that did not end with ';' as those were multi line assignments that the sed script above would fail to catch. Note, the same updates will need to be done for: __assign_str_len() __assign_rel_str() __assign_rel_str_len() I tested this with both an allmodconfig and an allyesconfig (build only for both).

2024-05-14media: bcm2835-unicam: Depend on COMMON_CLKLaurent Pinchart1-1/+1
The bcm2835-unicam driver calls the clk_set_min_rate() function, which is declared but not implemented on platforms that don't provide COMMON_CLK. This causes linkage failures with some configurations. Fix it by depending on COMMON_CLK. This only slightly restricts compilation testing, but not usage of the driver as all platforms on which the hardware can be found provide COMMON_CLK.

2024-05-10media: bcm2835-unicam: Convert to platform remove callback returning voidUwe Kleine-König1-4/+2
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

When the source device is operating above 1.5 Gbps per lane, it needs to send the Skew Calibration Sequence before sending any HS data. If the DPHY is initialized after the source stream is started, then it might miss the sequence and not be able to receive data properly. Move the start of source subdev to the end of the sequence to make sure everything is ready to receive data before the source starts streaming.

2024-04-19media: mipi-csis: Emit V4L2_EVENT_FRAME_SYNC eventsStefan Klug1-1/+33
The Samsung CSIS MIPI receiver provides a start-of-frame interrupt and a framecount register. As the CSI receiver is the hardware unit that lies closest to the sensor, the frame counter is the best we can get on these devices. In case of the ISI available on the i.MX8 M Plus it is also the only native start-of-frame signal available. This patch exposes the sof interrupt and the framecount as V4L2_EVENT_FRAME_SYNC event on the subdevice. It was tested on a Debix-Som-A with a 6.8-rc4 kernel.
