Subject: [PATCH 0/4] make I2C GPIO expander provided buttons work
Date: Wed, 21 Feb 2024 15:27:56 +0100 [thread overview]
Message-ID: <20240221142800.1958810-1-s.hauer@pengutronix.de> (raw)
The TQMa6UL board uses the gpio-keys driver with GPIOs provided by a
PCA9554 I2C GPIO expander. This currently doesn't work as the GPIOs
are read in a poller during an ongoing I2C transfer on the same bus.
This series fixes that by adding a slice to struct gpio_chip and
checking its availability before using it.
Sascha Hauer (4):
gpio: add slice support
gpio: pca953x: depend on i2c slice
input: gpio_keys: limit poll rate
input: gpio_keys: only use gpios in poller when not in use
drivers/gpio/gpio-pca953x.c | 2 ++
drivers/gpio/gpiolib.c | 11 +++++++++++
drivers/input/gpio_keys.c | 27 +++++++++++++++------------
include/gpio.h | 15 +++++++++++++++
