2016-09-09[media] v4l: vsp1: Report device model and rev through media device informationLaurent Pinchart1-0/+2
Instead of hardcoding the media device model and hardware revision to "VSP1" and 0 respectively, report the actual hardware device model and IP version number. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: wpf: Add flipping supportLaurent Pinchart1-0/+2
Vertical flipping is available on both Gen2 and Gen3, while horizontal flipping is only available on Gen3. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-28[media] v4l: vsp1: Add Cubic Look Up Table (CLU) supportLaurent Pinchart1-0/+3
The CLU processing block is a 2D/3D lookup table that converts the input three color component data into desired three color components using a lookup table. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-17[media] v4l: vsp1: Add FCP supportLaurent Pinchart1-0/+2
On some platforms the VSP performs memory accesses through an FCP. When that's the case get a reference to the FCP from the VSP DT node and enable/disable it at runtime as needed.

2016-06-17[media] v4l: vsp1: Don't handle clocks manuallyLaurent Pinchart1-1/+0
The power domain performs functional clock handling when using runtime PM, there's no need to enable and disable the clock manually. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-06-17[media] v4l: vsp1: Implement runtime PM supportLaurent Pinchart1-3/+0
Replace the manual refcount and clock management code by runtime PM. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-04-14[media] v4l: vsp1: Add support for the RPF alpha multiplier on Gen3Laurent Pinchart1-0/+1
The Gen3 RPF includes an alpha multiplier that can both multiply the alpha channel by a fixed global alpha value, and multiply the pixel components to convert the input to premultiplied alpha. As alpha premultiplication is available in the BRU for both Gen2 and Gen3 we handle it there and use the Gen3 alpha multiplier for global alpha multiplication only. This prevents conversion to premultiplied alpha if no BRU is present in the pipeline, that use case will be implemented later if needed.

2016-04-13[media] v4l: vsp1: Split display list manager from display listLaurent Pinchart1-1/+0
This clarifies the API and prepares display list support for being used to implement the request API. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-04-13[media] v4l: vsp1: Use pipeline display list to decide how to write to modulesLaurent Pinchart1-12/+0
This allows getting rid of the vsp1_device::use_dl field. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-19[media] v4l: vsp1: Configure device based on IP versionLaurent Pinchart1-2/+3
The IP version number carries enough information to identify the exact device instance features. Drop the related DT properties and use the IP version instead. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-19[media] v4l: vsp1: Add display list supportTakashi Saito1-0/+17
Display lists contain lists of registers and associated values to be applied atomically by the hardware. They lower the pressure on interrupt processing delays when reprogramming the device as settings can be prepared well in advance and queued to the hardware without waiting for the end of the current frame. Display list support is currently limited to the DRM pipeline.

2016-02-19[media] v4l: vsp1: Add VSP+DU supportLaurent Pinchart1-1/+2
Implement internal control of the VSP pipeline to be used by the DU DRM/KMS driver when using the VSP as an internal composer handled through DRM/KMS only. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-19[media] v4l: vsp1: Don't validate links when the userspace API is disabledLaurent Pinchart1-0/+2
As the pipeline is configured internally by the driver when the userspace API is disabled its configuration can be trusted and link validation isn't needed. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-19[media] v4l: vsp1: Make the userspace API optionalLaurent Pinchart1-0/+1
The R-Car Gen3 SoCs include VSP instances dedicated to the DU that will be controlled entirely by the rcar-du-drm driver through the KMS API. To support that use case make the userspace V4L2 API optional.

2016-02-19[media] v4l: vsp1: Make the BRU optionalLaurent Pinchart1-0/+1
Not all VSP instances have a BRU on R-Car Gen3, make it optional. Set the feature unconditionally for now, this will be fixed when adding Gen3 support. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
2016-02-19[media] v4l: vsp1: Make number of BRU inputs configurableLaurent Pinchart1-0/+1
The R-Car Gen3 family has 5-inputs BRUs, support them by making the number of BRU inputs configurable. As the driver assumes that the number of BRU inputs is equal to the number of RPFs, replace the BRU_MAX_INPUTS macro with VSP1_MAX_RPF to make the assumption apparent.

2016-02-19[media] v4l: vsp1: Move video device out of struct vsp1_rwpfLaurent Pinchart1-0/+1
To make the video device nodes optional we need to decouple the [rw]pf instances from the video devices. Move video devices out of struct vsp1_rwpf and instantiate them dynamically in the core driver code.

2014-12-23[media] v4l: vsp1: Remove support for platform dataLaurent Pinchart1-2/+12
Now that all platforms instantiate the VSP1 through DT, platform data support isn't needed anymore. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Acked-by: Simon Horman <horms+renesas@verge.net.au> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>

Modify the vsp1_device_get() function to return an error code instead of a pointer to the VSP1 device, and use the return value in the callers. Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>

2013-08-28[media] v4l: vsp1: Add support for RT clockLaurent Pinchart1-0/+1
The VSPR and VSPS instances use two clocks, the VSP1 system clock and the VSP1 realtime clock. Both of them need to be enabled to access the VSP1 registers. Add support for an optional RT clock and enable/disable it along with the system clock.

2013-08-18[media] v4l: Renesas R-Car VSP1 driverLaurent Pinchart1-0/+73
The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.
