Pull devicetree updates from Rob Herring:
"Bindings:
- Convert Qcom IOMMU, Amlogic timer, Freescale sec-v4.0, Toshiba
TC358764 display bridge, Parade PS8622 display bridge, and Xilinx
FPGA bindings to DT schema format
- Add qdu1000 and sa8775p SoC support to Qcom PDC interrupt
controller
- Add MediaTek MT8365 UART and SYSIRQ bindings
- Add Arm Cortex-A78C and X1C core compatibles
- Add vendor prefix for Novatek
- Remove bindings for stih415, sti416, stid127 platforms
- Drop uneeded quotes in schema files. This is preparation for
yamllint checking quoting for us.
- Add missing (unevaluated|additional)Properties constraints on child
node schemas
- Clean-up schema comments formatting
- Fix I2C and SPI node bus names in schema examples
- Clean-up some display compatibles schema syntax
- Fix incorrect references to lvds.yaml
- Gather all cache controller bindings in a common directory
DT core:
- Convert unittest to new void .remove platform device hook
- kerneldoc fixes for DT address of_pci_range_to_resource/
of_address_to_resource functions"

|
Exynos850 clock controller is comprised of several CMU units, generating
|
|
clocks for different domains. Those CMU units are modeled as separate device
|
|
tree nodes, and might depend on each other. Root clocks in that clock tree are
|
|
two external clocks:: OSCCLK (26 MHz) and RTCCLK (32768 Hz). Those external
|
|
clocks must be defined as fixed-rate clocks in dts.
|
|
|
|
CMU_TOP is a top-level CMU, where all base clocks are prepared using PLLs and
|
|
dividers; all other leaf clocks (other CMUs) are usually derived from CMU_TOP.
|
|
|
|
Each clock is assigned an identifier and client nodes can use this identifier
|
|
to specify the clock which they consume. All clocks available for usage
|
|
in clock consumer nodes are defined as preprocessor macros in
|
|
'dt-bindings/clock/exynos850.h' header.
