DRM_IOCTL_ETHOSU

#define DRM_IOCTL_ETHOSU	(		__access,

Value:

    DRM_IO ## __access(DRM_COMMAND_BASE + DRM_ETHOSU_ ## __id, \
               struct drm_ethosu_ ## __type)

DRM_IOCTL_ETHOSU() - Build a ethosu IOCTL number @__access: Access type. Must be R, W or RW. @__id: One of the DRM_ETHOSU_xxx id. @__type: Suffix of the type being passed to the IOCTL.

Don't use this macro directly, use the DRM_IOCTL_ETHOSU_xxx values instead.

Return: An IOCTL number to be passed to ioctl() from userspace.
