Reference the existing schema for the ADC, just define the other subnode schemas directly in the MFD schema. Add two examples so we have examples covering both the simple GPIO expander and the more complex with ADC and touchscreen. Some in-tree users do not follow the naming conventions for nodes so these DTS files need to be augmented to use proper node names like "adc", "pwm", "gpio", "keyboard-controller" etc before the bindings take effect on them.

ChangeLog v1->v2: - Split off the GPIO bindings to their own schema, as the old bindings didn't even have any GPIO bindings. Put the GPIO schema before this schema so we can use GPIO in the examples. - Drop nodename and pattern as STMPE is not a generic name. - Add maxItems to the resets. - Make wakeup-source just :true, as it is a generic property. - Move unevaluatedProperties for subnodes right before properties as requested. - Name devices "port-expander" in the examples. - Use lowercase hex in line init. --- .../devicetree/bindings/input/stmpe-keypad.txt | 41 --- .../bindings/input/touchscreen/stmpe.txt | 108 -------- .../devicetree/bindings/mfd/st,stmpe.yaml | 297 +++++++++++++++++++++ Documentation/devicetree/bindings/mfd/stmpe.txt | 42 --- 4 files changed, 297 insertions(+), 191 deletions(-) diff --git a/Documentation/devicetree/bindings/input/stmpe-keypad.txt b/Documentation/devicetree/bindings/input/stmpe-keypad.txt deleted file mode 100644 index 12bb771d66d4..000000000000 --- a/Documentation/devicetree/bindings/input/stmpe-keypad.txt +++ /dev/null @@ -1,41 +0,0 @@ -* STMPE Keypad - -Required properties: - - compatible : "st,stmpe-keypad" - - linux,keymap : See ./matrix-keymap.txt - -Optional properties: - - debounce-interval : Debouncing interval time in milliseconds - - st,scan-count : Scanning cycles elapsed before key data is updated - - st,no-autorepeat : If specified device will not autorepeat - - keypad,num-rows : See ./matrix-keymap.txt - - keypad,num-columns : See ./matrix-keymap.txt - -Example: - - stmpe_keypad { - compatible = "st,stmpe-keypad";
