    The old non-DRM Exynos MIPI driver does not support DeviceTree and
    requires board files. Our platforms do not provide such so the driver
    is not usable since a long time ago. All features provided by the
    driver (and associated s6e8ax0 panel driver) are already supported by
    newer DRM version so the old code can be removed.

  • cd98e85a6   gpu: ipu-v3: Add queued image conversion support ... Browse Code »

    This patch implements image conversion support using the IC tasks, with
    tiling to support scaling to and from images up to 4096x4096. Image
    rotation is also supported. Image conversion requests are added to
    a run queue under the IC tasks.

    The internal API is subsystem agnostic (no V4L2 dependency except
    for the use of V4L2 fourcc pixel formats).

    Callers prepare for image conversion by calling
    ipu_image_convert_prepare(), which initializes the parameters of
    the conversion. The caller passes in the ipu and IC task to use for
    the conversion, the input and output image formats, a rotation mode,
    and a completion callback and completion context pointer:

    struct ipu_image_converter_ctx *
    ipu_image_convert_prepare(struct ipu_soc *ipu, enum ipu_ic_task ic_task,
    struct ipu_image *in, struct ipu_image *out,
    enum ipu_rotate_mode rot_mode,
    ipu_image_converter_cb_t complete,
    void *complete_context);

    A new conversion context is created that is added to an IC task
    context queue. The caller is given the new conversion context,
    which can then be passed to the further APIs:

    int ipu_image_convert_queue(struct ipu_image_converter_run *run);

    This queues the given image conversion request run to a run queue,
    and starts the conversion immediately if the run queue is empty. Only
    the physaddr's of the input and output image buffers are needed,
    since the conversion context was created previously with
    ipu_image_convert_prepare(). When the conversion completes, the run
    pointer is returned to the completion callback.

    void ipu_image_convert_abort(struct ipu_image_converter_ctx *ctx);

    This will abort any active or pending conversions for this context.
    Any currently active or pending runs belonging to this context are
    returned via the completion callback with an error status.

    void ipu_image_convert_unprepare(struct ipu_image_converter_ctx *ctx);

    Unprepares the conversion context. Any active or pending runs will
    be aborted by calling ipu_image_convert_abort().

  • ac4708fab   gpu: ipu-v3: Add FSU channel linking support ... Browse Code »

    Adds functions to link and unlink source channels to sink
    channels in the FSU:

    int ipu_fsu_link(struct ipu_soc *ipu, int src_ch, int sink_ch);
    int ipu_fsu_unlink(struct ipu_soc *ipu, int src_ch, int sink_ch);

    The channels numbers are usually IDMAC channels, but they can also be
    channels that do not transfer data to or from memory. The following
    convenience functions can be used in place of ipu_fsu_link/unlink()
    when both source and sink channels are IDMAC channels:

    int ipu_idmac_link(struct ipuv3_channel *src, struct ipuv3_channel *sink);
    int ipu_idmac_unlink(struct ipuv3_channel *src, struct ipuv3_channel *sink);

    So far the following links are supported:

    IPUV3_CHANNEL_IC_PRP_ENC_MEM -> IPUV3_CHANNEL_MEM_ROT_ENC
    PUV3_CHANNEL_IC_PRP_VF_MEM -> IPUV3_CHANNEL_MEM_ROT_VF
    IPUV3_CHANNEL_IC_PP_MEM -> IPUV3_CHANNEL_MEM_ROT_PP
    IPUV3_CHANNEL_CSI_DIRECT -> IPUV3_CHANNEL_CSI_VDI_PREV

    More links can be added to the fsu_link_info[] array.

    For all video modes we support currently, we always get 2 slots for
    a plane by using the current existing dynamic DMFC FIFO allocation
    mechanism. So, let's change to use the static one to simplify the
    code. This also makes it easier to implement the atomic mode setting
    as we don't need to handle allocation failure cases then.

    imx-drm probing fix

    Commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc module autoloading")
    broke probing of the imx-drm driver in the non-modular case because the
    unset dev->of_node during probing of imx-ipuv3-crtc would cause the
    component matching to fail. This patch patch instead matches against
    an of_node pointer stored in platform data, allowing dev->of_node to
    be left unset for the platform probed imx-ipuv3-crtc devices.

  • 310944d14   drm/imx: Match imx-ipuv3-crtc components using device node in platform data ... Browse Code »

    The component master driver imx-drm-core matches component devices using
    their of_node. Since commit 950b410dd1ab ("gpu: ipu-v3: Fix imx-ipuv3-crtc
    module autoloading"), the imx-ipuv3-crtc dev->of_node is not set during
    probing. Before that, of_node was set and caused an of: modalias to be
    used instead of the platform: modalias, which broke module autoloading.

    On the other hand, if dev->of_node is not set yet when the imx-ipuv3-crtc
    probe function calls component_add, component matching in imx-drm-core
    fails. While dev->of_node will be set once the next component tries to
    bring up the component master, imx-drm-core component binding will never
    succeed if one of the crtc devices is probed last.

    Add of_node to the component platform data and match against the
    pdata->of_node instead of dev->of_node in imx-drm-core to work around
    this problem.
