arm64: defconfig: Enable Rockchip io-domain driver
[ Upstream commit7c8b77f815
] Heiko Stübner justified pretty well the change in commite330eb86ba
("ARM: multi_v7_defconfig: enable Rockchip io-domain driver"). This change is also needed for arm64 rockchip boards, so, do the same for arm64. 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 successfully tune UHS cards etc, it should get built in. Otherwise, tuning will fail with, dwmmc_rockchip fe320000.dwmmc: All phases bad! mmc0: tuning execution failed: -5 Signed-off-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Acked-by: Robin Murphy <robin.murphy@arm.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
