Several io power domains on the Quartz64-A operate at 1.8v. Add the pmu_io_domains definition to enable support for this. This permits the enablement of the following features: sdio - wifi support sdhci - mmc-hs200-1_8v Signed-off-by: Peter Geis <pgwipeout@gmail.com> --- arch/arm64/boot/dts/rockchip/rk3566-quartz64-a.dts | 13 +++++++++++++ 1 file changed, 13 insertions(+)
