From 6a45b0e2589fafd7fc501a5fbd0ab56689a08124 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Thu, 28 May 2020 16:58:43 +0200 Subject: gpiolib: Introduce gpiochip_irqchip_add_domain() The function connects an IRQ domain to a gpiochip and reuses gpiochip_to_irq() which is provided by gpiolib. gpiochip_irqchip_* and regmap_irq partially provide the same functionality. This function will help to connect just the minimal functionality of the gpiochip_irqchip which is needed to work together with regmap-irq.
