Convert the VIA VT8500 and WonderMedia WM8xxx UART Controller to newer DT schema. Created DT schema based on the .txt file which had `compatible`, `reg`, `interrupts` and `clocks` as required properties. Additions to the original binding - changed the file name from vt8500-uart to via,vt8500-uart.yaml - removed unnecessary alias from the example. Signed-off-by: Kanak Shilledar <kanakshilledar@xxxxxxxxx> --- Changes in v3: - Removed Rob and myself from maintainers and added Alexey. - Fixed commit message which mentioned "greg and jiri as maintainers". - Elaborated changelog for v2. Changes in v2: - Rebased changes - Changed maintainers to have Rob and remove Greg and Jiri. VT8500 is orphaned according to the maintainers file. - Replaced `compatible` property description with comments. --- .../bindings/serial/via,vt8500-uart.yaml | 46 +++++++++++++++++++ .../bindings/serial/vt8500-uart.txt | 27 ----------- 2 files changed, 46 insertions(+), 27 deletions(-) create mode 100644 Documentation/devicetree/bindings/serial/via,vt8500-uart.yaml delete mode 100644 Documentation/devicetree/bindings/serial/vt8500-uart.txt diff --git a/Documentation/devicetree/bindings/serial/via,vt8500-uart.yaml b/Documentation/devicetree/bindings/serial/via,vt8500-uart.yaml new file mode 100644 index 000000000000..9c6819241a49 --- /dev/null +++ b/Documentation/devicetree/bindings/serial/via,vt8500-uart.yaml @@ -0,0 +1,46 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) + +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/serial/via,vt8500-uart.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: VIA VT8500 and WonderMedia WM8xxx UART Controller + +maintainers: + - Alexey Charkov <alchark@xxxxxxxxx> + +allOf: + - $ref: serial.yaml + +properties: + compatible: + enum: + - via,vt8500-uart # up to WM8850/WM8950 + - wm,wm8880-uart # for WM8880 and later + + clocks: + maxItems: 1 + + interrupts: + maxItems: 1 + + reg: + maxItems: 1 + +required: + - compatible + - clocks + - interrupts + - reg + +unevaluatedProperties: false + +examples: + - | + serial@d8200000 { + compatible = "via,vt8500-uart"; + reg = <0xd8200000 0x1040>; + interrupts = <32>; + clocks = <&clkuart0>; + }; diff --git a/Documentation/devicetree/bindings/serial/vt8500-uart.txt b/Documentation/devicetree/bindings/serial/vt8500-uart.txt deleted file mode 100644 index 2b64e6107fb3..000000000000 --- a/Documentation/devicetree/bindings/serial/vt8500-uart.txt +++ /dev/null @@ -1,27 +0,0 @@ -* VIA VT8500 and WonderMedia WM8xxx UART Controller - -Required properties: -- compatible: should be "via,vt8500-uart" (for VIA/WonderMedia chips up to and - including WM8850/WM8950), or "wm,wm8880-uart" (for WM8880 and later) - -- reg: base physical address of the controller and length of memory mapped - region. - -- interrupts: hardware interrupt number - -- clocks: shall be the input parent clock phandle for the clock.
