Subject: [PATCH v3 1/2] dt-bindings: gpio: Add STMPE YAML DT schema
This adds a schema for the STMPE GPIO that while it is used a
lot in the kernel tree is anyway missing its bindings.
Signed-off-by: Linus Walleij <linus.walleij@...aro.org>
---
ChangeLog v2->v3:
- Use a compact hog node schema backed by the standard hog
schema.
ChangeLog v1->v2:
- New patch split off from the MFD patch.

+title: STMicroelectonics Port Expander (STMPE) GPIO Block
+
+description: STMicroelectronics Port Expander (STMPE) is a series of slow
+ bus controllers for various expanded peripherals such as GPIO, keypad,
+ touchscreen, ADC, PWM or rotator. It can contain one or several different
+ peripherals connected to SPI or I2C. These bindings pertain to the
+ GPIO portions of these expanders.
