The dma_mask and coherent_dma_mask values were never set. This prevented the media omap_vout driver from loading successfully. Tested on a Pandaboard and Beagle XM board. Signed-off-by:

We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

Commit b2ce5617 ("media: i2c: fix warning same module names") renamed the adv7511 module in the media tree to adv7511-v4l2. This patch does the same rename for the driver name and device id to keep the naming consistent. Since the cobalt driver loads this module, it had to be renamed there as well. Signed-off-by:

In imx7s.dtsi the node name for the CSI multiplexer is "csi-mux", not "csi_mux", so fix all the references in the document. This fixes the following error when the instructions are followed: Unable to parse link: Invalid argument (22) While at it, provide the "media-ctl -p" output from 5.2 kernel version, so that users can see a more updated output.

Correct handling of OUTPUT buffers field and make v4l2-compliance happy. Signed-off-by:
-
Stanimir Varbanov authored
This refactors code for start/stop streaming vb2 operations and adds a state machine handling similar to the one in stateful codec API documentation. One major change is that now the HFI session is started on STREAMON(OUTPUT) and stopped on REQBUF(OUTPUT,count=0), during that time STREAMOFF(CAP,OUT) just flush buffers but doesn't stop the session. The other major change is that now the capture and output queues are completely separated. Signed-off-by:

Until now we returned num_output_bufs set during reqbuf but that could be wrong when we implement stateful Codec API. So get the minimum buffers for capture from HFI. This is supposed to be called after stream header parsing, i.e. after dequeue v4l2 event for change resolution. Signed-off-by:

This adds three more helper functions: * for internal buffers reallocation, applicable when we are doing dynamic resolution change * for initial buffer processing of capture and output queue buffer types All of them will be needed for stateful Codec API support. Signed-off-by:

Allwinner A31 has introduced a new memory mapping and a reset line. The difference in memory mapping are : - In the configure register there is a new sample bit and Allwinner has introduced the active threshold feature. - In the status register a new STAT bit is present. Note: CGPO and DRQ_EN bits are removed on A31 but present on A13 and on new SoCs like A64/H6. This is actually not an issue as these bits are togglable and new SoCs have a dedicated bindings. Introduce this bindings to make a difference since this generation. And declare the reset line required since A31. Signed-off-by:

A bugfix introduce a link failure in configurations without CONFIG_MODULES: In file included from drivers/media/usb/dvb-usb/pctv452e.c:20:0: drivers/media/usb/dvb-usb/pctv452e.c: In function 'pctv452e_frontend_attach': drivers/media/dvb-frontends/stb0899_drv.h:151:36: error: weak declaration of 'stb0899_attach' being applied to a already existing, static definition The problem is that the !IS_REACHABLE() declaration of stb0899_attach() is a 'static inline' definition that clashes with the weak definition. I further observed that the bugfix was only done for one of the five users of stb0899_attach(), the other four still have the problem. This reverts the bugfix and instead addresses the problem by not dropping the reference count when calling '->detach()', instead we call this function directly in dvb_frontend_put() before dropping the kref on the front-end. I first submitted this in early 2018, and after some discussion it was apparently discarded. While there is a long-term plan in place, that plan is obviously not nearing completion yet, and the current kernel is still broken unless this patch is applied.
