[PATCH 0/4] make I2C GPIO expander provided buttons work

[Sascha Hauer]

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
