Subject: [PATCH v2 3/4] irqchip/meson-gpio: add select trigger type callback
Date: Wed, 19 Jan 2022 15:08:08 +0800 [thread overview]
Message-ID: <20220119070809.15563-4-qianggui.song@amlogic.com> (raw)
In-Reply-To: <20220119070809.15563-1-qianggui.song@amlogic.com>
Due to some chips may use different registers and offset, provide
a set trigger type call back.
