-+* OCTEON SD/MMC Host Controller
-+
-+This controller is present on some members of the Cavium OCTEON SoC
-+family, provide an interface for eMMC, MMC and SD devices.  There is a
-+single controller that may have several "slots" connected.  These
-+slots appear as children of the main controller node.
-+The DMA engine is an integral part of the controller block.
-+
-+Required properties:
-+- compatible : Should be "cavium,octeon-6130-mmc" or "cavium,octeon-7890-mmc"
-+- reg : Two entries:
-+      1) The base address of the MMC controller register bank.
-+      2) The base address of the MMC DMA engine register bank.
-+- interrupts :
-+      For "cavium,octeon-6130-mmc": two entries:
-+      1) The MMC controller interrupt line.
-+      2) The MMC DMA engine interrupt line.
-+      For "cavium,octeon-7890-mmc": nine entries:
-+      1) The next block transfer of a multiblock transfer has completed (BUF_DONE)
-+      2) Operation completed successfully (CMD_DONE).
-+      3) DMA transfer completed successfully (DMA_DONE).
-+      4) Operation encountered an error (CMD_ERR).
-+      5) DMA transfer encountered an error (DMA_ERR).
-+      6) Switch operation completed successfully (SWITCH_DONE).
-+      7) Switch operation encountered an error (SWITCH_ERR).
-+      8) Internal DMA engine request completion interrupt (DONE).
-+      9) Internal DMA FIFO underflow (FIFO).
-+- #address-cells : Must be <1>
-+- #size-cells : Must be <0>
-+
-+Required properties of child nodes:
-+- compatible : Should be "cavium,octeon-6130-mmc-slot".
-+- reg : The slot number.
-+
-+Optional properties of child nodes:
-+- cd-gpios : Specify GPIOs for card detection
-+- wp-gpios : Specify GPIOs for write protection
-+- power-gpios : Specify GPIOs for power control
-+- cavium,bus-max-width : The number of data lines present in the slot.
-+      Default is 8.
-+- spi-max-frequency : The maximum operating frequency of the slot.
-+      Default is 52000000.
-+- cavium,cmd-clk-skew : the amount of delay (in pS) past the clock edge
-+      to sample the command pin.
-+- cavium,dat-clk-skew : the amount of delay (in pS) past the clock edge
-+      to sample the data pin.
-+
-+Example:
-+      mmc@1180000002000 {
-+              compatible = "cavium,octeon-6130-mmc";
-+              reg = <0x11800 0x00002000 0x0 0x100>,

++* OCTEON SD/MMC Host Controller
++
++This controller is present on some members of the Cavium OCTEON SoC
++family, provide an interface for eMMC, MMC and SD devices.  There is a
++single controller that may have several "slots" connected.  These
++slots appear as children of the main controller node.
++The DMA engine is an integral part of the controller block.
++
++Required properties:
++- compatible : Should be "cavium,octeon-6130-mmc" or "cavium,octeon-7890-mmc"
++- reg : Two entries:
++      1) The base address of the MMC controller register bank.
++      2) The base address of the MMC DMA engine register bank.
++- interrupts :
++      For "cavium,octeon-6130-mmc": two entries:
++      1) The MMC controller interrupt line.
++      2) The MMC DMA engine interrupt line.
++      For "cavium,octeon-7890-mmc": nine entries:
++      1) The next block transfer of a multiblock transfer has completed (BUF_DONE)
++      2) Operation completed successfully (CMD_DONE).
++      3) DMA transfer completed successfully (DMA_DONE).
++      4) Operation encountered an error (CMD_ERR).
++      5) DMA transfer encountered an error (DMA_ERR).
++      6) Switch operation completed successfully (SWITCH_DONE).
++      7) Switch operation encountered an error (SWITCH_ERR).
++      8) Internal DMA engine request completion interrupt (DONE).
++      9) Internal DMA FIFO underflow (FIFO).
++- #address-cells : Must be <1>
++- #size-cells : Must be <0>
++
++Required properties of child nodes:
++- compatible : Should be "cavium,octeon-6130-mmc-slot".
++- reg : The slot number.
++
++Optional properties of child nodes:
++- cd-gpios : Specify GPIOs for card detection
++- wp-gpios : Specify GPIOs for write protection
++- power-gpios : Specify GPIOs for power control
++- cavium,bus-max-width : The number of data lines present in the slot.
++      Default is 8.
++- spi-max-frequency : The maximum operating frequency of the slot.
++      Default is 52000000.
++- cavium,cmd-clk-skew : the amount of delay (in pS) past the clock edge
++      to sample the command pin.
++- cavium,dat-clk-skew : the amount of delay (in pS) past the clock edge
++      to sample the data pin.
++
++Example:
++      mmc@1180000002000 {
++              compatible = "cavium,octeon-6130-mmc";
++              reg = <0x11800 0x00002000 0x0 0x100>,
