Browse Source 
The ZX296718 clocks are statically listed and registered. More
clock will be added later.

Device Tree Clock bindings for ZTE zx296718
This binding uses the common clock binding[1].
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
Required properties:
- compatible : shall be one of the following:
"zte,zx296718-topcrm":
zx296718 top clock selection, divider and gating
"zte,zx296718-lsp0crm" and
"zte,zx296718-lsp1crm":
zx296718 device level clock selection and gating
- reg: Address and length of the register set
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/zx296718-clock.h
for the full list of zx296718 clock IDs.
