Subject: [PATCH v2 2/4] gpio: aspeed: Remove the name for bank array
Date: Fri, 30 Aug 2024 11:40:45 +0800 [thread overview]
Message-ID: <20240830034047.2251482-3-billy_tsai@aspeedtech.com> (raw)
In-Reply-To: <20240830034047.2251482-1-billy_tsai@aspeedtech.com>
The bank array name is only used to determine if the GPIO offset is valid,
and this condition can be replaced by checking if the offset exceeds the
ngpio property.
