-These properties are common to multiple MMC host controllers. Any host
-that requires the respective functionality should implement them using
-these definitions.
-
-Interpreted by the OF core:
-- reg: Registers location and length.
-- interrupts: Interrupts used by the MMC controller.
-
-Card detection:
-If no property below is supplied, host native card detect is used.
-Only one of the properties in this section should be supplied:
-  - broken-cd: There is no card detection available; polling must be used.
-  - cd-gpios: Specify GPIOs for card detection, see gpio binding
-  - non-removable: non-removable slot (like eMMC); assume always present.
-
-Optional properties:
-- bus-width: Number of data lines, can be <1>, <4>, or <8>.  The default
-  will be <1> if the property is absent.
-- wp-gpios: Specify GPIOs for write protection, see gpio binding
-- cd-inverted: when present, polarity on the CD line is inverted. See the note
-  below for the case, when a GPIO is used for the CD line
-- wp-inverted: when present, polarity on the WP line is inverted. See the note
-  below for the case, when a GPIO is used for the WP line
-- max-frequency: maximum operating clock frequency
-- no-1-8-v: when present, denotes that 1.8v card voltage is not supported on
-  this system, even if the controller claims it is.
-- cap-sd-highspeed: SD high-speed timing is supported
-- cap-mmc-highspeed: MMC high-speed timing is supported
-- cap-power-off-card: powering off the card is safe
-- cap-sdio-irq: enable SDIO IRQ signalling on this interface
-- full-pwr-cycle: full power cycle of the card is supported

-*NOTE* on CD and WP polarity. To use common for all SD/MMC host controllers line
-polarity properties, we have to fix the meaning of the "normal" and "inverted"
-line levels. We choose to follow the SDHCI standard, which specifies both those
-lines as "active low." Therefore, using the "cd-inverted" property means, that
-the CD line is active high, i.e. it is high, when a card is inserted. Similar
-logic applies to the "wp-inverted" property.
-
-CD and WP lines can be implemented on the hardware in one of two ways: as GPIOs,
-specified in cd-gpios and wp-gpios properties, or as dedicated pins. Polarity of
-dedicated pins can be specified, using *-inverted properties. GPIO polarity can
-also be specified using the OF_GPIO_ACTIVE_LOW flag. This creates an ambiguity
-in the latter case. We choose to use the XOR logic for GPIO CD and WP lines.
-This means, the two properties are "superimposed," for example leaving the
-OF_GPIO_ACTIVE_LOW flag clear and specifying the respective *-inverted
-property results in a double-inversion and actually means the "normal" line
-polarity is in effect.
-
-Optional SDIO properties:
-- keep-power-in-suspend: Preserves card power during a suspend/resume cycle
-- enable-sdio-wakeup: Enables wake up of host system on SDIO IRQ assertion
-
-Example:
-
-sdhci@ab000000 {
-	compatible = "sdhci";
-	reg = <0xab000000 0x200>;
-	interrupts = <23>;
-	bus-width = <4>;
-	cd-gpios = <&gpio 69 0>;
-	cd-inverted;
-	wp-gpios = <&gpio 70 0>;
-	max-frequency = <50000000>;
-	keep-power-in-suspend;
-	enable-sdio-wakeup;
