Subject: [PATCH V1 03/10] Input: da9061: onkey driver

From: Steve Twiss <stwiss.opensource@...semi.com>

Support for the DA9061 onkey is added into the DA9063 onkey driver.

The of_device_id match array is expanded to support "dlg,da9061-onkey" as a
valid .compatible string. A new chip configuration register map listed in
da9061_regs is added and linked to this device tree compatible string in
the .data section.

Copyright header is updated to add DA9061 in its description and the module
description macro is extended to include DA9061.

Kconfig is updated to reflect support for DA9061/62/63.

Signed-off-by: Steve Twiss <stwiss.opensource@...semi.com>

This patch applies against linux-next and v4.8

Dmitry,

The DA9063 onkey driver is modified to support the DA9061 onkey.
Because of earlier work with DA9062 it is a simple matter to extend this
for DA9061 by adding a new compatible string and register mapping.
  { .compatible = "dlg,da9061-onkey", .data = &da9061_regs },

Regards,
Steve Twiss, Dialog Semiconductor Ltd.
