Subject: [PATCH v1 2/4] gpio: dwapb: Read GPIO base from gpio-base property
Date: Mon, 26 Jul 2021 15:54:34 +0300 [thread overview]
Message-ID: <20210726125436.58685-2-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20210726125436.58685-1-andriy.shevchenko@linux.intel.com>
For backward compatibility with some legacy devices introduce
a new (*) property gpio-base to read GPIO base. This will allow
further cleanup of the driver.
*) Note, it's not new for GPIO library since mockup driver is
using it already.
