This series adds the I2C bus recovery support on Kunpeng 920/930.
We're using HiSilicon I2C controller on Kunpeng 930 and Designware
I2C controller on Kunpeng 920. For both platform, the SCL/SDA pins
are multiplexed with GPIOs. Both driver use generic GPIO recovery
method and we need to switch the pin mutiplexing before/after the
recovery process. We use ACPI method to help on the pin mux switching
which is also introduced in this series.

i2c: hisi: Add generic GPIO bus recovery support
i2c: designware: Add ACPI assisted recovery support

a friendly ping ...
Hi Designware maintainers and Wolfram, any comments for this?
thanks.
