Subject: [PATCH] pinctrl: samsung: Use bank name as irqchip name
Date: Tue, 9 Jun 2020 10:23:29 +0200 [thread overview]
Message-ID: <20200609082329.10184-1-m.szyprowski@samsung.com> (raw)
In-Reply-To: CGME20200609082341eucas1p2e24e71598af14d994520b79494e96b15@eucas1p2.samsung.com
Use the bank name as the irqchip name. This name is later visible in
/proc/interrupts, what makes it possible to easily identify each
GPIO interrupt.
/proc/interrupts before this patch:
143: 0 exynos4210_wkup_irq_chip 7 Edge hdmi
144: 0 exynos4210_wkup_irq_chip 6 Level wm8994
145: 1 exynos4210_wkup_irq_chip 7 Edge max77686-pmic, max77686-rtc
146: 1 exynos_gpio_irq_chip 3 Edge 3-0048
/proc/interrupts after this patch:
143: 0 gpx3 7 Edge hdmi
144: 0 gpx3 6 Level wm8994
145: 1 gpx0 7 Edge max77686-pmic, max77686-rtc
146: 1 gpm2 3 Edge 3-0048
