This fixes a bug where the driver tries to retune while a sdport-issued tuning request is already in progress. Signed-off-by: Mario Bălănică <[email protected]>
SD cards can only be switched back to 3.3V after a power cycle. The firmware does not currently implement card power control (and some boards don't even have a switch to begin with), so we need to ensure that the card is not initialized before being able to safely change signaling on the host side. This should only happen after the card is unplugged. Signed-off-by: Mario Bălănică <[email protected]>
