-Subject: [PATCH v5 1/2] pinctrl: Add driver for Awinic AW9523/B I2C GPIO
- Expander
-Date: Mon, 25 Jan 2021 19:22:18 +0100
-
-The Awinic AW9523(B) is a multi-function I2C gpio expander in a
-TQFN-24L package, featuring PWM (max 37mA per pin, or total max
-power 3.2Watts) for LED driving capability.
-
-It has two ports with 8 pins per port (for a total of 16 pins),
-configurable as either PWM with 1/256 stepping or GPIO input/output,
-1.8V logic input; each GPIO can be configured as input or output
-independently from each other.
-
-This IC also has an internal interrupt controller, which is capable
-of generating an interrupt for each GPIO, depending on the
-configuration, and will raise an interrupt on the INTN pin to
-advertise this to an external interrupt controller.
