 - clock-names: Should contain the following:
 	"sdio" - SDIO source clock (required)
 	"enable" - gate clock which used for enabling/disabling the device (required)
+	"2x_enable" - gate clock controlling the device for some special platforms (optional)
 
 Optional properties:
 - assigned-clocks: the same with "sdio" clock
 - assigned-clock-parents: the default parent of "sdio" clock
+- pinctrl-names: should be "default", "state_uhs"
+- pinctrl-0: should contain default/high speed pin control
+- pinctrl-1: should contain uhs mode pin control

+PHY DLL delays are used to delay the data valid window, and align the window
+to sampling clock. PHY DLL delays can be configured by following properties,
+and each property contains 4 cells which are used to configure the clock data
+write line delay value, clock read command line delay value, clock read data
+positive edge delay value and clock read data negative edge delay value.
+Each cell's delay value unit is cycle of the PHY clock.
