The patch you sent is basically in two halves: - the writes to the registers - the calling of omap3_iva_idle(). If I patch only the writes to the registers then suspend still fails. If I patch only the calling of omap3_iva_idle() then suspend works. If I patch both the writes to the registers and the calling of omap3_iva_idle() then suspend works.
