Subject: [PATCH RFC v1 2/2] pinctrl: meson: wire up the gpio_chip's set_config callback
Date: Sat, 11 Apr 2020 19:03:56 +0200 [thread overview]
Message-ID: <20200411170356.1578031-3-martin.blumenstingl@googlemail.com> (raw)
In-Reply-To: <20200411170356.1578031-1-martin.blumenstingl@googlemail.com>
Use gpiochip_generic_config for the gpio_chip's set_config callback so
GPIO flags like GPIO_PULL_UP or GPIO_PULL_DOWN can be used in the board
.dts descriptions.
This is required for some Meson8m2 boards where GPIO_BSD_EN provides the
"MUTE" signal and requires enabling the internal pull-up resistor.
