2018-08-29media: camss: add missing includesArnd Bergmann
Multiple files in this driver fail to build because of missing header inclusions: drivers/media/platform/qcom/camss/camss-csiphy-2ph-1-0.c: In function 'csiphy_hw_version_read': drivers/media/platform/qcom/camss/camss-csiphy-2ph-1-0.c:31:18: error: implicit declaration of function 'readl_relaxed'; did you mean 'xchg_relaxed'?

Changing a user control value can trigger an event to other users. Add support for that.

2018-08-02media: camss: Add support for 10-bit grayscale formatsTodor Tomov
Add support for 10-bit packed V4L2_PIX_FMT_Y10P (on 8x16 and 8x96) and unpacked V4L2_PIX_FMT_Y10 (on 8x96 only) pixel formats. Signed-off-by: Todor Tomov <todor.tomov@linaro.org> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

Add support for RAW MIPI14 format for RDI mode on 8x96. Signed-off-by: Todor Tomov <todor.tomov@linaro.org> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

Use the PRDI mode on 8x96 to allow to configure RAW MIPI10 to Plain16 format conversion. Signed-off-by: Todor Tomov <todor.tomov@linaro.org> Signed-off-by: Hans Verkuil <hansverk@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>
2018-08-02media: camss: csid: Different format support on source padTodor Tomov
Usually the format on the source pad is the same as on the sink pad. However the CSID is able to do some format conversions. To support this make the format on the source pad selectable amongst a list of formats. This list can be different for each sink pad format. This is still not used but will be when the format conversions are implemented.

2018-08-02media: camss: Format configuration per hardware versionTodor Tomov
As the 8x16 and 8x96 support different formats, separate the arrays which contain the supported formats. For the VFE also add separate arrays for RDI and PIX subdevices.

2018-08-02media: camss: csid: Add support for 8x96Todor Tomov
CSID hardware modules on 8x16 and 8x96 are similar. There is no need to duplicate the code by adding separate versions. Just update the register macros to return the correct register addresses.

2018-08-02media: camss: Add basic runtime PM supportTodor Tomov
There is a PM domain for each of the VFE hardware modules. Add support for basic runtime PM support to be able to control the PM domains. When a PM domain needs to be powered on - a device link is created. When a PM domain needs to be powered off - its device link is removed. This allows separate and independent control of the PM domains. Suspend/Resume is still not supported.

2018-08-02media: camss: Add 8x96 resourcesTodor Tomov
Add structs with 8x96 resources. As the number of CSIPHY, CSID and VFE hardware modules is different on 8x16 and 8x96 select the number at runtime and allocate needed structures dynamically.

2018-08-02media: camss: csid: Configure data type and decode format properlyTodor Tomov
The CSID decodes the input data stream. When the input comes from the Test Generator the format of the stream is set on the source media pad. When the input comes from the CSIPHY the format is the one on the sink media pad. Use the proper format for each case.
