Reported-by: Ville-Pekka Vainio <vpivaini@cs.helsinki.fi> The reporter noticed SD Card clock is running again after resume. After looking at the code I saw I missed two tricks, this will force it off after resume and will do better generally depending on what the last SD Card packet was. Since bulk read packet is normally last action (which set the clock off even without this) the old patch worked for normal cases. But after resume, the last packet on the wire was not a bulk transfer and we didn't take care about the clock then. Signed-off-by: Andy Green <andy@openmoko.com>
