46 These ioctls can be used to get or set an EDID associated with an input
56 pad of the subdevice. If there is no EDID support for the given ``pad``
59 To get the EDID data the application has to fill in the ``pad``,
60 ``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
61 array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
63 ``edid`` points to. The ``edid`` pointer must point to memory at least
67 ``blocks`` to the actual number of blocks. If there are no EDID blocks
75 total number of available EDID blocks and it will return 0 without
76 copying any data. This is an easy way to discover how many EDID blocks
