Subject: [PATCH -next v1 1/1] gpio: gpio-aspeed-sgpio: Fix wrong hwirq in irq handler.
Date: Tue, 7 Sep 2021 17:55:25 +0800 [thread overview]
Message-ID: <20210907095525.24668-2-steven_lee@aspeedtech.com> (raw)
In-Reply-To: <20210907095525.24668-1-steven_lee@aspeedtech.com>
The current hwirq is calculated based on the old GPIO pin order(input
GPIO range is from 0 to ngpios - 1).
It should be calculated based on the current GPIO input pin order(input
GPIOs are 0, 2, 4, ..., (ngpios - 1) * 2).
