Hi everyone,

This patchset adds the device tree entry to the CFA-10049 board of its i2c
muxer. This muxer controls sub-buses that contains three Nuvoton NAU7802
ADCs and a NXP PCA955 GPIO expander. Support for these will be added


Changes from v1:
  - Fixed indentation in patch 1
  - Fixed arrays allocation for the dt bindings
  - Various fixes in the documentation

Maxime Ripard (3):
  i2c: i2c-mux-gpio: Use devm_kzalloc instead of kzalloc
  i2c: mux: Add dt support to i2c-mux-gpio driver
  ARM: dts: cfa10049: Add the i2c muxer buses to the CFA-10049
