Fourth version can be found here:
https://lore.kernel.org/patchwork/cover/974998/
Changes since v4:
* Implemented divider ops and used clk-composite as suggested
by Sascha Hauer.
Changes since v3:
* Added a composite clock type to get rid of some complexity
from clk-imx8mq. This new composite clock type will also be
used by all the imx8 socs that will follow.
* Added back the reviewed-by tag.

+* Clock bindings for NXP i.MX8M Quad
+
+Required properties:
+- compatible: Should be "fsl,imx8mq-ccm"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- clocks: list of clock specifiers, must contain an entry for each required
+ entry in clock-names
+- clock-names: should include the following entries:
+ - "ckil"
+ - "osc_25m"
+ - "osc_27m"
+ - "clk_ext1"
+ - "clk_ext2"
+ - "clk_ext3"
+ - "clk_ext4"
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx8mq-clock.h
+for the full list of i.MX8M Quad clock IDs.

From: Lucas Stach <l.stach@pengutronix.de>
The SCCG is a new PLL type introduced on i.MX8. Add support for this.
The driver currently misses the PLL lock check, as the preliminary
documentation mentions lock configurations, but is quiet about where
to find the actual lock status signal.

Since a lot of clocks on imx8 are formed by a mux, gate, predivider and
divider, the idea here is to combine all of those into one more complex
clock type, therefore moving the complexity inside the composite clock and
outside of the SoC specific clock driver.

From: Lucas Stach <l.stach@pengutronix.de>
Add driver for the Clock Control Module found on i.MX8MQ.
This is largely based on the downstream driver from Anson Huang and
Bai Ping at NXP, with only some small adaptions to mainline from me.
