Add MMC controller support for HiSilicon HI3670 SoC reusing the HI3660 Designware MMC driver. There are 2 DWMMC controllers present in this SoC: 1. DWMMC1 is used for SD card (SD) 2. DWMMC2 is used for WiFi (SDIO) Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> --- arch/arm64/boot/dts/hisilicon/hi3670.dtsi | 37 +++++++++++++++++++++++ 1 file changed, 37 insertions(+) -- 2.17.1
