From d2ff98b7926e0956c0b92f7d5066cd8a65e7dfef Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Wed, 29 Nov 2023 13:06:14 +0200 Subject: dt-bindings: input: gpio-keys: Allow optional dedicated wakeirq Allow configuring an optional dedicated wakeirq for gpio-keys that some SoCs have. Let's use the common interrupt naming "irq" and "wakeup" that we already have in use for some drivers and subsystems like i2c framework. Note that the gpio-keys interrupt property is optional. If only a gpio property is specified, the driver tries to translate the gpio into an interrupt.
