::fdf::WireUnownedResult< ::fuchsia_hardware_sdio::DriverDevice::DoRwTxn> DoRwTxn (::fuchsia_hardware_sdio::wire::SdioRwTxn && txn)Clients are responsible for performing the following cache operations:
After read requests:
- Call zx_cache_flush with ZX_CACHE_FLUSH_DATA | ZX_CACHE_FLUSH_INVALIDATE on buffers that
have been mapped by the client.
- Call zx_vmo_op_range with ZX_VMO_OP_CACHE_CLEAN_INVALIDATE on all other buffers.
Note that writing to any portion of a buffer before DoRwTxn has returned can corrupt the
received data.
Before write requests:
- Call zx_cache_flush with ZX_CACHE_FLUSH_DATA on buffers that have been mapped by the
client.
- Call zx_vmo_op_range with ZX_VMO_OP_CACHE_CLEAN on all other buffers.

::fdf::WireUnownedResult< ::fuchsia_hardware_sdio::DriverDevice::RequestCardReset> RequestCardReset ()Requests that the core driver hard reset the card and perform the SDIO initialization
sequence again. The callback will be called after the card has been re-initialized, and in
the meantime all IO calls from this client will return ZX_ERR_SHOULD_WAIT. If an error
occurs during initialization then all subsequent IO calls will return ZX_ERR_IO_NOT_PRESENT.
The only way to recover from this situation would be to call `RequestCardReset()` again.
The SDIO core driver will wait for all clients to call this method before performing the
reset and re-initialization. After the reset clients will have to perform their own
initialization steps again, such as calling `EnableFnIntr()` or `UpdateBlockSize()`.
VMO registration methods can always be called regardless of the reset state.
The specific method used to hard reset the card is platform- or board-specific; examples
include toggling a reset GPIO or power cycling the card.

::fdf::WireUnownedResult< ::fuchsia_hardware_sdio::DriverDevice::PerformTuning> PerformTuning ()Perform tuning in the background. Clients can use this to update the host controller delay
settings in case the bus delay has changed due to temperature or other factors. For example,
clients could call this periodically, or only in response to data CRC errors. The amount of
time this call takes (and the amount of time that other requests are blocked for) is
controller-dependent.
Returns `ZX_ERR_ALREADY_BOUND` if another call to `PerformTuning()` is already pending.
Otherwise returns `ZX_OK` or an error value if the SDMMC driver's tuning process failed (see
the [SDMMC protocol](/sdk/banjo/fuchsia.hardware.sdmmc/sdmmc.fidl)).
