-From 528a5cd576861f90f51398c707c602a79623492d Mon Sep 17 00:00:00 2001
-From: Hans de Goede <hdegoede@redhat.com>
-Date: Thu, 5 Sep 2013 19:52:41 -0300
-Subject: [PATCH] ARM: sunxi: Add driver for SD/MMC hosts found on Allwinner
- sunxi SoCs
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The Allwinner sunxi mmc host uses dma in bus-master mode using a built-in
-designware idmac controller, which is identical to the one found in the mmc-dw
-hosts. However the rest of the host is not identical to mmc-dw, it deals with
-sending stop commands in hardware which makes it significantly different
-from the mmc-dw devices.

-+* Allwinner sunxi MMC controller
-+
-+The highspeed MMC host controller on Allwinner SoCs provides an interface
-+for MMC, SD and SDIO types of memory cards.
-+
-+Supported maximum speeds are the ones of the eMMC standard 4.5 as well
-+as the speed of SD standard 3.0.
-+Absolute maximum transfer rate is 200MB/s
-+
-+Required properties:
-+ - compatible : "allwinner,sun4i-a10-mmc" or "allwinner,sun5i-a13-mmc"
-+ - reg : mmc controller base registers
-+ - clocks : a list with 2 phandle + clock specifier pairs
-+ - clock-names : must contain "ahb" and "mod"
-+ - interrupts : mmc controller interrupt
-+
-+Optional properties:
-+ - resets : phandle + reset specifier pair
-+ - reset-names : must contain "ahb"
-+ - for cd, bus-width and additional generic mmc parameters
-+ please refer to mmc.txt within this directory
-+
-+Examples:
-+ - Within .dtsi:
-+ mmc0: mmc@01c0f000 {
-+ compatible = "allwinner,sun5i-a13-mmc";
-+ reg = <0x01c0f000 0x1000>;
-+ clocks = <&ahb_gates 8>, <&mmc0_clk>;
-+ clock-names = "ahb", "mod";
-+ interrupts = <0 32 4>;
-+ status = "disabled";
-+ };
-+
-+ - Within dts:
-+ mmc0: mmc@01c0f000 {
-+ pinctrl-names = "default", "default";
-+ pinctrl-0 = <&mmc0_pins_a>;
-+ pinctrl-1 = <&mmc0_cd_pin_reference_design>;
-+ bus-width = <4>;
-+ cd-gpios = <&pio 7 1 0>; /* PH1 */
-+ cd-inverted;
-+ status = "okay";
-+ };
