Yes, the patch works. We applied and compiled it with 4.14 and
4.17-rc3. We tested on our hardware with 4.14.

Only for 4.14 an #include <linux/regulator/consumer.h> was missing. I
Guess the API changed here a little in the meantime.

Because we do not have a controllable power supply on our board we see
the following complaint. But I think it is intentional and ok, right?

	[    1.715963] bu21029 0-0040: 0-0040 supply vdd not found, using dummy regulator
	[    1.723806] input: bu21029 as /devices/soc0/soc/2100000.aips-bus/21a0000.i2c/i2c-0/0-0040/input/input0 

> + - vdd-supply              : power supply for the controoler

There is a typo in controller.

What's the next step?

Greetings,
Mark
