media: platform: stm32: don't print an error on probe deferral

2020-03-12T16:27:46Z

Change stm32-cec driver to not print an error message when the device probe operation is deferred. Signed-off-by: Etienne Carriere Reviewed-by: Philippe Cornu Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: platform: stm32: defer probe for auxiliary clock

2020-03-12T16:27:31Z

Change stm32-cec driver to defer probe when auxiliary clock "hdmi-cec" is registered in the system not has not been probed yet. Signed-off-by: Etienne Carriere Reviewed-by: Philippe Cornu Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: media/platform: rename VFL_TYPE_GRABBER to _VIDEO

2020-02-24T15:54:14Z

'GRABBER' is a weird name, all other types map to the /dev device names. Rename to 'VIDEO' to be consistent with the other types. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab

media: stm32-dcmi: Use dma_request_chan() instead dma_request_slave_channel()

2020-02-24T14:24:52Z

dma_request_slave_channel() is a wrapper on top of dma_request_chan() eating up the error code. By using dma_request_chan() directly the driver can support deferred probing against DMA.

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

2019-08-29T13:23:02Z

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

2019-08-19T15:06:38Z

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

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

2019-08-19T15:04:28Z

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

2019-08-19T15:03:43Z

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()

2019-08-07T20:08:33Z

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).
