On many Marvell SoCs, the pins used for the SDIO interface are part of
|
|
the MPP pins, that are muxable pins. In order to get the muxing of
|
|
those pins correct, this commit integrates the mvsdio driver with the
|
|
pinctrl infrastructure by calling devm_pinctrl_get_select_default()
|
|
during ->probe().
|
|
|
|
Note that we permit this function to fail because not all Marvell
|
|
platforms have yet been fully converted to using the pinctrl
|
|
infrastructure.
