+* 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.
