[PATCH v3 0/7] dt-bindings: first batch of dt-schema conversions for Amlogic Meson bindings

[PATCH v3 0/7] dt-bindings: first batch of dt-schema conversions for Amlogic Meson bindings

[Neil Armstrong]

Batch conversion of the following bindings:
- amlogic-efuse.txt
- amlogic-meson-mx-efuse.txt
- meson-wdt.txt
- meson-ir.txt
- rtc-meson.txt
- amlogic,meson6-timer.txt
- amlogic,meson-gx.txt
- amlogic,meson-pcie.txt

Martin Blumenstingl was also added as bindings maintainer for Meson6/8/8b
related bindings.

Remaining conversions:
- meson,pinctrl.txt
- pwm-meson.txt
- amlogic,meson-gpio-intc.txt
- amlogic,meson-mx-sdio.txt
- rtc-meson-vrtc.txt
- amlogic,axg-sound-card.txt

[PATCH v3 3/7] dt-bindings: watchdog: convert meson-wdt.txt to dt-schema

[Neil Armstrong]

Convert the Amlogic Meson6 SoCs Watchdog timer bindings to dt-schema.

Take in account the used interrupts property.

The "amlogic,meson8-wdt" representation has been simplified
since there's no users of this compatible used along the
"amlogic,meson6-wdt".

-- clocks     : A list of phandle + clock-specifier pairs for the clocks listed in clock-names.
-- clock-names: Should contain the following:
-	"core" - Main peripheral bus clock
-	"clkin0" - Parent clock of internal mux

-  The driver has an internal mux clock which switches between clkin0 and clkin1 depending on the

-Amlogic Meson AXG DWC PCIE SoC controller
-
-Amlogic Meson PCIe host controller is based on the Synopsys DesignWare PCI core.
-It shares common functions with the PCIe DesignWare core driver and
-inherits common properties defined in
-Documentation/devicetree/bindings/pci/snps,dw-pcie.yaml.
-
-Additional properties are described here:
-
-Required properties:
-- compatible:
-	should contain :
-	- "amlogic,axg-pcie" for AXG SoC Family
-	- "amlogic,g12a-pcie" for G12A SoC Family
-	to identify the core.
-- reg:
-	should contain the configuration address space.
-- reg-names: Must be
-	- "elbi"	External local bus interface registers
-	- "cfg"		Meson specific registers
-	- "config"	PCIe configuration space
-- reset-gpios: The GPIO to generate PCIe PERST# assert and deassert signal.
-- clocks: Must contain an entry for each entry in clock-names.
-- clock-names: Must include the following entries:
-	- "pclk"       PCIe GEN 100M PLL clock
-	- "port"       PCIe_x(A or B) RC clock gate
-	- "general"    PCIe Phy clock
-- resets: phandle to the reset lines.
-- reset-names: must contain "port" and "apb"
-       - "port"        Port A or B reset
-       - "apb"         Share APB reset
-- phys: should contain a phandle to the PCIE phy
-- phy-names: must contain "pcie"
-
-- device_type:
-	should be "pci". As specified in snps,dw-pcie.yaml
