Pull devicetree updates from Rob Herring:
 "DT core:

   - Fix ref counting errors in interrupt parsing code

   - Allow "nonposted-mmio" property per device and on non-Apple h/w

   - Use typed accessors in platform driver code

   - Fix mismatch between DT MAX_PHANDLE_ARGS and
     NR_FWNODE_REFERENCE_ARGS and increase the maximum number args

   - Rework of_resolve_phandles() to use __free() cleanup and fix ref
     count error

   - Use of_prop_cmp() in a few more places

   - Improve make_fit.py script error handling

  DT bindings:

   - Update DT property ordering rules for properties within groups
     (i.e. common suffix)

   - Update DT submitting-patches doc to cover sending .dts patches and
     SoC maintainer rules on being warning free against linux-next

   - Add ti,tps53681, ti,tps53681, Maxim max15301, max15303, and
     max20751 to trivial devices

   - Add Renesas RZ/V2H(P) and Allwinner H616 support to Arm Mali
     Bifrost GPU. Add Samsung exynos7870 support to Arm Mail Midgard.

   - Rework qcom,ebi2 and samsung,exynos4210-sram memory controller
     bindings to split child node properties. Fix the LAN9115 binding to
     use the child node schema so all properties are documented.

   - Convert nxp,lpc3220-mic and Altera ECC manager bindings to schema

   - Fix some issues with LVDS display panels causing validation
     warnings

Arm has introduced a new v10 GPU architecture that replaces the Job Manager
interface with a new Command Stream Frontend. It adds firmware driven
command stream queues that can be used by kernel and user space to submit
jobs to the GPU.

Add the initial schema for the device tree that is based on support for
RK3588 SoC. The minimum number of clocks is one for the IP, but on Rockchip
platforms they will tend to expose the semi-independent clocks for better
power management.

v6:
- Add Maxime's and Heiko's acks

v5:
- Move the opp-table node under the gpu node

v4:
- Fix formatting issue

v3:
- Cleanup commit message to remove redundant text
- Added opp-table property and re-ordered entries
- Clarified power-domains and power-domain-names requirements for RK3588.
- Cleaned up example

Note: power-domains and power-domain-names requirements for other platforms
are still work in progress, hence the bindings are left incomplete here.

v2:
- New commit
