[PATCH v5] Input: add bu21029 touch driver

Add Rohm BU21029 resistive touch panel controller support with I2C
interface.

Is the patch ready to be pushed upstream? Is there anything I still need to do?

I would like to kindly remind you of the BU21029 touch screen driver.
Could you please forward it to the mainline kernel?

Sorry for the delay. Could you please tell me if the patch below (shoudl
apply on top of your v5 version) works?

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
