299 *
300 * That's 18 bits. Really. Nothing more. And the USB people have
301 * documented these eighteen bits as some kind of glorious
302 * virtual data structure.
303 *
304 * Let's not fall in that trap. We'll just encode it as a simple
305 * unsigned int. The encoding is:
306 *
307 * - max size: bits 0-1 (00 = 8, 01 = 16, 10 = 32, 11 = 64)
Michael Trimarchide39f8c2008-11-26 17:41:34 +0100308 * - direction: bit 7 (0 = Host-to-Device [Out],
309 * (1 = Device-to-Host [In])
wdenk012771d2002-03-08 21:31:05 +0000310 * - device: bits 8-14
311 * - endpoint: bits 15-18
312 * - Data0/1: bit 19
Michael Trimarchide39f8c2008-11-26 17:41:34 +0100313 * - pipe type: bits 30-31 (00 = isochronous, 01 = interrupt,
314 * 10 = control, 11 = bulk)
wdenk012771d2002-03-08 21:31:05 +0000315 *
316 * Why? Because it's arbitrary, and whatever encoding we select is really
317 * up to us. This one happens to share a lot of bit positions with the UHCI
318 * specification, so that much of the uhci driver can just mask the bits
319 * appropriately.
