Hi,
First of all, good to see this patch set being submitted again!
We're using an older version of your patch set for some time and
they're working good for us.

Some gpio chips may have get/set operations that
can sleep. gpio_set_value() only works for chips
which do not sleep, for the others we will get a
kernel warning. Using gpio_set_value_cansleep()
will work for both chips that do sleep and those
who don't.

() callback with chan_id set to 0, the i2c-mux-gpio
will use it as an index into mux->data.values and it will
actually select the bus with reg = <1>.

the
i2c-mux-gpio driver will actually use values[0], hence 1
as the gpio selection value.

In the initial case when no reg_defaults values are
provided and no register value was added to the cache
yet, the cache_present bitmap is NULL. If this function
is invoked for any register it should return false
(i.e. the register is not cached) instead of true.

Instead the regmap_writeable() check should be done
in _regmap_write() to prevent callers from writing
to read-only registers.
