The v7.0 kernel includes the Mali C55 driver. We were carrying a private
copy of the corresponding headers, updating to the mainline version
ensures that we test the latest API.

This update also imports two new headers, drm.h and drm_mode.h. They do
not contain SPDX license headers in the upstream kernel yet, which would
cause a CI failure. Modify them manually until a patch fixing the issue
([1]) gets merged upstream.

I went through the content, ignoring the new drm.h and drm_mode.h files
as they are new ... and the updates to existing files look sane, and I
can't see anything that looks like our previous updates being lost so:

> + * struct drm_mode_get_connector - Get connector metadata.
> + *
> + * User-space can perform a GETCONNECTOR ioctl to retrieve information about a
> + * connector. User-space is expected to retrieve encoders, modes and properties
> + * by performing this ioctl at least twice: the first time to retrieve the
> + * number of elements, the second time to retrieve the elements themselves.
> + *
> + * To retrieve the number of elements, set @count_props and @count_encoders to
> + * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
> + * drm_mode_modeinfo element.
> + *
> + * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
> + * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
> + * @count_encoders to their capacity.
> + *
> + * Performing the ioctl only twice may be racy: the number of elements may have
> + * changed with a hotplug event in-between the two ioctls. User-space is
> + * expected to retry the last ioctl until the number of elements stabilizes.
> + * The kernel won't fill any array which doesn't have the expected length.
> + *
> + * **Force-probing a connector**
> + *
> + * If the @count_modes field is set to zero and the DRM client is the current
> + * DRM master, the kernel will perform a forced probe on the connector to
> + * refresh the connector status, modes and EDID. A forced-probe can be slow,
> + * might cause flickering and the ioctl will block.
> + *
> + * User-space needs to force-probe connectors to ensure their metadata is
> + * up-to-date at startup and after receiving a hot-plug event. User-space
> + * may perform a forced-probe when the user explicitly requests it. User-space
> + * shouldn't perform a forced-probe in other situations.

> + * This struct holds frame-buffer metadata. There are two ways to use it:
> + *
> + * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
> + *   ioctl to register a new frame-buffer. The new frame-buffer object ID will
> + *   be set by the kernel in @fb_id.
> + * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
> + *   fetch metadata about an existing frame-buffer.
> + *
> + * In case of planar formats, this struct allows up to 4 buffer objects with
> + * offsets and pitches per plane. The pitch and offset order are dictated by
> + * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
> + *
> + *     YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
> + *     interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
> + *     samples.
> + *
> + * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
> + * ``offsets[1]``.
> + *
> + * To accommodate tiled, compressed, etc formats, a modifier can be specified.
> + * For more information see the "Format Modifiers" section. Note that even
> + * though it looks like we have a modifier per-plane, we in fact do not. The
> + * modifier for each plane must be identical. Thus all combinations of
> + * different data layouts for multi-plane formats must be enumerated as
> + * separate modifiers.
> + *
> + * All of the entries in @handles, @pitches, @offsets and @modifier must be
> + * zero when unused. Warning, for @offsets and @modifier zero can't be used to
> + * figure out whether the entry is used or not since it's a valid value (a zero
> + * offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

+ * struct drm_mode_get_connector - Get connector metadata.
+ *
+ * User-space can perform a GETCONNECTOR ioctl to retrieve information about a
+ * connector. User-space is expected to retrieve encoders, modes and properties
+ * by performing this ioctl at least twice: the first time to retrieve the
+ * number of elements, the second time to retrieve the elements themselves.
+ *
+ * To retrieve the number of elements, set @count_props and @count_encoders to
+ * zero, set @count_modes to 1, and set @modes_ptr to a temporary struct
+ * drm_mode_modeinfo element.
+ *
+ * To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr,
+ * @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and
+ * @count_encoders to their capacity.
+ *
+ * Performing the ioctl only twice may be racy: the number of elements may have
+ * changed with a hotplug event in-between the two ioctls. User-space is
+ * expected to retry the last ioctl until the number of elements stabilizes.
+ * The kernel won't fill any array which doesn't have the expected length.
+ *
+ * **Force-probing a connector**
+ *
+ * If the @count_modes field is set to zero and the DRM client is the current
+ * DRM master, the kernel will perform a forced probe on the connector to
+ * refresh the connector status, modes and EDID. A forced-probe can be slow,
+ * might cause flickering and the ioctl will block.
+ *
+ * User-space needs to force-probe connectors to ensure their metadata is
+ * up-to-date at startup and after receiving a hot-plug event. User-space
+ * may perform a forced-probe when the user explicitly requests it. User-space
+ * shouldn't perform a forced-probe in other situations.

+ * struct drm_mode_fb_cmd2 - Frame-buffer metadata.
+ *
+ * This struct holds frame-buffer metadata. There are two ways to use it:
+ *
+ * - User-space can fill this struct and perform a &DRM_IOCTL_MODE_ADDFB2
+ *   ioctl to register a new frame-buffer. The new frame-buffer object ID will
+ *   be set by the kernel in @fb_id.
+ * - User-space can set @fb_id and perform a &DRM_IOCTL_MODE_GETFB2 ioctl to
+ *   fetch metadata about an existing frame-buffer.
+ *
+ * In case of planar formats, this struct allows up to 4 buffer objects with
+ * offsets and pitches per plane. The pitch and offset order are dictated by
+ * the format FourCC as defined by ``drm_fourcc.h``, e.g. NV12 is described as:
+ *
+ *     YUV 4:2:0 image with a plane of 8-bit Y samples followed by an
+ *     interleaved U/V plane containing 8-bit 2x2 subsampled colour difference
+ *     samples.
+ *
+ * So it would consist of a Y plane at ``offsets[0]`` and a UV plane at
+ * ``offsets[1]``.
+ *
+ * To accommodate tiled, compressed, etc formats, a modifier can be specified.
+ * For more information see the "Format Modifiers" section. Note that even
+ * though it looks like we have a modifier per-plane, we in fact do not. The
+ * modifier for each plane must be identical. Thus all combinations of
+ * different data layouts for multi-plane formats must be enumerated as
+ * separate modifiers.
+ *
+ * All of the entries in @handles, @pitches, @offsets and @modifier must be
+ * zero when unused. Warning, for @offsets and @modifier zero can't be used to
+ * figure out whether the entry is used or not since it's a valid value (a zero
+ * offset is common, and a zero modifier is &DRM_FORMAT_MOD_LINEAR).

+ *
+ * User-space fills @height, @width, @bpp and @flags. If the IOCTL succeeds,

+ *
+ * The value of @bpp is a color-mode number describing a specific format
