The io-domain driver is necessary to notify the soc about voltages changes happening on supplying regulators. Probably the most important user right now is the mmc tuning code, where the soc needs to get notified when the voltage is dropped to the 1.8V point. As this option is necessary to sucessfully tune UHS cards etc, it should get built in. Signed-off-by: Heiko Stuebner <heiko.stuebner@collabora.com> --- When booting a Veyron-Jerry from an sd-card it got stuck, as the tuning failed due to the missing voltage notification and the mmc completely fails initialization of the card, if this happens. With this option enabled, I could again boot from my sd-card. This is based on the arch/arm/configs/multi_v7_defconfig | 2 ++ 1 file changed, 2 insertions(+)
