Merge tag 'imx8mq-4.21' of... 

Merge tag 'imx8mq-4.21' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/late

i.MX8MQ device tree support for 4.21:
 - It contains the initial device tree support for i.MX8MQ - the first
   ARM64 i.MX processor.  It features a quad Cortex-A53 core that
   operates at speeds of up to 1.3 GHz, a Cortex-M4 core for
   low-power processing, a DRAM controller that supports 32-bit/16-bit
   LPDDR4/DDR4/DDR3L memory, and hardware acceleration for 4K video
   playback.
 - A couple of patches from Baruch that add watchdog device for i.MX8MQ
   enable it for imx8mq-evk board.

* 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.
