-* Clock bindings for Freescale i.MX7ULP
-
-i.MX7ULP Clock functions are under joint control of the System
-Clock Generation (SCG) modules, Peripheral Clock Control (PCC)
-modules, and Core Mode Controller (CMC)1 blocks
-
-The clocking scheme provides clear separation between M4 domain
-and A7 domain. Except for a few clock sources shared between two
-domains, such as the System Oscillator clock, the Slow IRC (SIRC),
-and and the Fast IRC clock (FIRCLK), clock sources and clock
-management are separated and contained within each domain.
-
-M4 clock management consists of SCG0, PCC0, PCC1, and CMC0 modules.
-A7 clock management consists of SCG1, PCC2, PCC3, and CMC1 modules.
-
-Note: this binding doc is only for A7 clock domain.
-
-System Clock Generation (SCG) modules:
----------------------------------------------------------------------
-The System Clock Generation (SCG) is responsible for clock generation
-and distribution across this device. Functions performed by the SCG
-include: clock reference selection, generation of clock used to derive
-processor, system, peripheral bus and external memory interface clocks,
-source selection for peripheral clocks and control of power saving
-clock gating mode.
-
-Required properties:
-
-- compatible:	Should be "fsl,imx7ulp-scg1".
-- reg : 	Should contain registers location and length.
-- #clock-cells:	Should be <1>.
-- clocks:	Should contain the fixed input clocks.
-- clock-names:  Should contain the following clock names:
-		"rosc", "sosc", "sirc", "firc", "upll", "mpll".
-
-Peripheral Clock Control (PCC) modules:
----------------------------------------------------------------------
-The Peripheral Clock Control (PCC) is responsible for clock selection,
-optional division and clock gating mode for peripherals in their
-respected power domain
-
-Required properties:
-- compatible:	Should be one of:
-		  "fsl,imx7ulp-pcc2",
-		  "fsl,imx7ulp-pcc3".
-- reg : 	Should contain registers location and length.
-- #clock-cells:	Should be <1>.
-- clocks:	Should contain the fixed input clocks.
-- clock-names:  Should contain the following clock names:
-		"nic1_bus_clk", "nic1_clk", "ddr_clk", "apll_pfd2",
-		"apll_pfd1", "apll_pfd0", "upll", "sosc_bus_clk",
-		"mpll", "firc_bus_clk", "rosc", "spll_bus_clk";
-
-The clock consumer should specify the desired clock by having the clock
-ID in its "clocks" phandle cell.
-See include/dt-bindings/clock/imx7ulp-clock.h
-for the full list of i.MX7ULP clock IDs of each module.
