media: stm32-dcmi: Delete an unnecessary of_node_put() call in dcmi_probe()

2019-08-29T13:23:02+00:00

A null pointer would be passed to a call of the function “of_node_put” immediately after a call of the function “of_graph_get_next_endpoint” failed at one place. Remove this superfluous function call. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: add support of several sub-devices

2019-08-19T15:06:38+00:00

Add support of several sub-devices within pipeline instead of a single one. This allows to support a CSI-2 camera sensor connected through a CSI-2 to parallel bridge. Signed-off-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: add media controller support

2019-08-19T15:05:33+00:00

Add media controller support to dcmi in order to walk within remote subdevices pipeline. Signed-off-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: trace the supported fourcc/mbus_code

2019-08-19T15:04:28+00:00

Add a trace of the set of supported fourcc/mbus_code which intersect between DCMI and source sub-device. Signed-off-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: improve sensor subdev naming

2019-08-19T15:03:43+00:00

Rename "subdev" entity struct field to "source" to prepare for several subdev support. Move asd field on top of entity struct. Acked-by: Sakari Ailus Signed-off-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: Remove dev_err() usage after platform_get_irq()

2019-08-07T20:08:33+00:00

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. // @@ 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(...); ) ... } // While we're here, remove braces on if statements that only have one statement (manually).

media: stm32-dcmi: fix irq = 0 case

2019-06-05T19:28:32+00:00

Manage the irq = 0 case, where we shall return an error. Fixes: b5b5a27bee58 ("media: stm32-dcmi: return appropriate error codes during probe") Signed-off-by: Fabien Dessenne Reported-by: Pavel Machek Acked-by: Pavel Machek Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: return appropriate error codes during probe

2019-04-30T17:48:14+00:00

During probe, return the provided errors value instead of -ENODEV. This allows the driver to be deferred probed if needed. Signed-off-by: Fabien Dessenne Acked-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: fix crash when subdev do not expose any formats

2019-04-22T15:09:23+00:00

Do not access sd_formats[] if num_of_sd_formats is zero, ie subdev sensor didn't expose any formats. Signed-off-by: Hugues Fruchet Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
