Subject: [PATCH v2 2/2] gpiolib: Show more info for interrupt only lines in debugfs
Date: Thu, 30 May 2024 22:12:30 +0300	[thread overview]
Message-ID: <20240530191418.1138003-3-andriy.shevchenko@linux.intel.com> (raw)
In-Reply-To: <20240530191418.1138003-1-andriy.shevchenko@linux.intel.com>

Show more info for interrupt only lines in debugfs. It's useful
to monitor the lines that have been never requested as GPIOs,
but IRQs.

Reviewed-by: Linus Walleij <linus.walleij@linaro.org>
