To support HS200 and UHS mode, mmc core will call init_card() to execute tuning: - sdio: init_card can be executed at runtime resume. - sd and mmc: init_card can be executed at resume or runtime resume, which depends on MMC_CAP_RUNTIME_RESUME capability. On rk3288 SoC, host will get DRTO interrupt when host send command to read tuning data. This will spend more than 111ms: drto_ms = drto_clks * 1000 / bus_hz = 111ms. And the total tuning time will be more than 400ms. So we should add MMC_CAP_RUNTIME_RESUME capability to execute tuning at runtime resume. Only if we do so, can we pass resume test.
