+Clock bindings for ST-Ericsson U300 System Controller Clocks
+
+Bindings for the gated system controller clocks:
+
+Required properties:
+- compatible: must be "stericsson,u300-syscon-clk"
+- #clock-cells: must be <0>
+- clock-type: specifies the type of clock:
+ 0 = slow clock
+ 1 = fast clock
+ 2 = rest/remaining clock
+- clock-id: specifies the clock in the type range
+
+Optional properties:
+- clocks: parent clock(s)
+
+The available clocks per type are as follows:
+
+Type: ID: Clock:
+-------------------
+0 0 Slow peripheral bridge clock
+0 1 UART0 clock
+0 4 GPIO clock
+0 6 RTC clock
+0 7 Application timer clock
+0 8 Access timer clock
+
+1 0 Fast peripheral bridge clock
+1 1 I2C bus 0 clock
+1 2 I2C bus 1 clock
+1 5 MMC interface peripheral (silicon) clock
+1 6 SPI clock
+
+2 3 CPU clock
+2 4 DMA controller clock
+2 5 External Memory Interface (EMIF) clock
+2 6 NAND flask interface clock
+2 8 XGAM graphics engine clock
+2 9 Shared External Memory Interface (SEMI) clock
+2 10 AHB Subsystem Bridge clock
+2 12 Interrupt controller clock
