Required Properties:
- - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a'
- - reg: From mmc bindings: Register location and length.
- - clocks: From clock bindings: Handles to clock inputs.
- - clock-names: From clock bindings: Tuple including "clk_xin" and "clk_ahb"
+ - compatible: Compatibility string. Must be 'arasan,sdhci-8.9a' or
+ 'apm,arasan,sdhci-8.9a'
+ - reg: First resource is the SDHC register location and length.
+ Second optional resource is the bridge translation register location
+ and length if required.
- interrupts: Interrupt specifier
- interrupt-parent: Phandle for the interrupt controller that services
interrupts for this device.
+Optional Properties:
+ - clocks: For format, refer to clock bindings. It requires two clocks if
+ specified - AHB clock and SDHC clock.
+ - clock-names: For format, refer to clock bindings. The clock corresponding
+ to the AHBC clock must be named "clk_ahb". The clock
+ corresponding to the SDHC clock must be named "clk_xin".
