Subject: [PATCH 2/3] arm64: dts: hisilicon: hi3670: Add MMC controller support
Date: Thu, 28 Feb 2019 21:15:10 +0530	[thread overview]
Message-ID: <20190228154511.17566-3-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20190228154511.17566-1-manivannan.sadhasivam@linaro.org>

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)
