The ST-Ericsson U300 platform is getting removed, so this driver is no
longer needed.

-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

-Bindings for the MMC/SD card clock:
-
-Required properties:
-- compatible: must be "stericsson,u300-syscon-mclk"
-- #clock-cells: must be <0>
-
-Optional properties:
-- clocks: parent clock(s)
