usb: gadget: f_fs: add usb_functionfs_descs_head_v2 structure
The structure can be used with user space tools that use the new functionfs description format, for example as follows: static const struct { struct usb_functionfs_descs_head_v2 header; __le32 fs_count; __le32 hs_count; struct { … } fs_desc; struct { … } hs_desc; } descriptors = { .header = { .magic = cpu_to_le32(FUNCTIONFS_DESCRIPTORS_MAGIC_V2), .length = cpu_to_le32(sizeof(descriptors)), .flags = cpu_to_le32(FUNCTIONFS_HAS_FS_DESC | FUNCTIONFS_HAS_HS_DESC) }, .fs_count = cpu_to_le32(X), .fs_desc = { … }, .hs_count = cpu_to_le32(Y), .hs_desc = { … } }; Signed-off-by: Michal Nazarewicz <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
