Subject: [PATCH v5 06/16] mfd: input: bd71828: Add power-key support
Date: Mon, 18 Nov 2019 08:56:24 +0200
Message-ID: <3d9db6ef3de2e851c9e00e1e20aa5bdbf7e2b09c.1574059625.git.matti.vaittinen@fi.rohmeurope.com> (raw)
In-Reply-To: <cover.1574059625.git.matti.vaittinen@fi.rohmeurope.com>

Use gpio_keys to send power input-event to user-space when power
button (short) press is detected.
