-* NXP LPC1850 Clock Control Unit (CCU)
-
-Each CGU base clock has several clock branches which can be turned on
-or off independently by the Clock Control Units CCU1 or CCU2. The
-branch clocks are distributed between CCU1 and CCU2.
-
- - Above text taken from NXP LPC1850 User Manual.
-
-This binding uses the common clock binding:
-    Documentation/devicetree/bindings/clock/clock-bindings.txt
-
-Required properties:
-- compatible:
-	Should be "nxp,lpc1850-ccu"
-- reg:
-	Shall define the base and range of the address space
-	containing clock control registers
-- #clock-cells:
-	Shall have value <1>.  The permitted clock-specifier values
-	are the branch clock names defined in table below.
-- clocks:
-	Shall contain a list of phandles for the base clocks routed
-	from the CGU to the specific CCU. See mapping of base clocks
-	and CCU in table below.
-- clock-names:
-	Shall contain a list of names for the base clock routed
-	from the CGU to the specific CCU. Valid CCU clock names:
-	"base_usb0_clk",  "base_periph_clk", "base_usb1_clk",
-	"base_cpu_clk",   "base_spifi_clk",  "base_spi_clk",
-	"base_apb1_clk",  "base_apb3_clk",   "base_adchs_clk",
-	"base_sdio_clk",  "base_ssp0_clk",   "base_ssp1_clk",
-	"base_uart0_clk", "base_uart1_clk",  "base_uart2_clk",
-	"base_uart3_clk", "base_audio_clk"
-
-Which branch clocks that are available on the CCU depends on the
-specific LPC part. Check the user manual for your specific part.
-
-A list of CCU clocks can be found in dt-bindings/clock/lpc18xx-ccu.h.
