[PATCH 0/4] ARM: amlogic: add i2c support to Amlogic's gxbb family

[PATCH 0/4] ARM: amlogic: add i2c support to Amlogic's gxbb family

[Jerome Brunet]

Add support for the meson i2c controller found on the gxbb SoC family
This patchset adds 1 i2c in the AO domain and 3 in the EE domain (A,B,C).
There is 1 last i2c in the EE domain (D) but it is actually not connected
to the pad of the SoC, so there is no point in adding it here.

Patches for the i2c [0] driver and pinctrl [1] have been sent in
dedicated series

[PATCH 4/4] ARM64: dts: gxbb: add i2c bus

[Jerome Brunet]

Add nodes for i2c bus on gxbb based platforms.
On the OdroidC2 (I2C A) and P200 (I2C B), the pull-up resistor are
present directly on the board. This indicates that these pins are
dedicated to i2c.
